PREFACE

 

         This manual is designed to make the transition from a student of speech-language pathology to a student clinician in the Harding University Speech Clinic a little easier, and a little less frightening.  This handbook of guidelines should introduce you to the procedures utilized in our clinic, and answer many of the questions that may develop during your practicum as a student speech clinician.  There is no way to make this manual thorough enough to answer all questions, but as a supplement to the Clinical Practicum class sessions, it should prove a useful guide.

 

         As all of your course instructors have told you, each institution of learning, as well as each employment setting uses different methods, procedures, etc. and that any guide should be used as an example in that setting and not as Òthe correct way.Ó  The information in this manual will prove useful in completing future job responsibilities, but there is seldom one correct way of completing a task.

 

         The format is designed so that you can print and place this manual along with all of your Communication Sciences and Disorders (CSD) course syllabi in your COMD 235 portfolio.  It is strongly suggested that you also include all handouts from each course.  Several students in the past have been able to avoid repeating a course at the graduate level by producing the course syllabus and handouts.

 

         It is the intention of the faculty and clinical supervisors that you have a clinical experience that is both pleasant and productive; however, the well-being of each client is our ultimate responsibility.  As we all work together, may we serve the clients needs and continue in service to the glory of our Lord.

THE SPEECH AND HEARING CLINIC

 

         The Communication Department operates the Speech Clinic at Harding University as part of its Communication Sciences and Disorders training program,.  There are presently two divisions of the clinic:  1) the on campus clinic, and 2) the off-campus practicum program.  This latter division may include joint projects with the Harding Academy, Searcy Head Start Center, the Sunshine School, area hospitals and specified schools accepting Harding speech clinicians completing their off-campus placement for future certification.

        

         The primary purpose of the Harding University Speech Clinic is to provide a basic undergraduate training for future speech-language pathologists and audiologists.  In so doing, the clinic encourages and permits student clinicians to observe and work with communicatively handicapped individuals under the supervision of ASHA certified speech-language pathologists and audiologists.

 

         A second purpose of the clinic is to provide out-patient speech and hearing services.  Working cooperatively with Harding University and other health and educational programs, the clinic seeks to fulfill a need for services in the east central Arkansas area.  Clients enrolled in the clinic include all age ranges needing clinical services in the areas of articulation and language.  These individuals are referred to the clinic by Harding faculty, public school teachers, physicians, nurses, psychologists, rehabilitation counselors, other speech pathologists, and parents themselves.  No formal referral is required for a client to be eligible for therapy, but such a referral is preferred.

 

         Therapy and diagnosis are carried out by qualified faculty members and students in training.  As outlined in more specific detail later, the supervisors receive regular written reports of therapy plans and progress.  A weekly meeting between the supervisor and the student clinician is often necessary during the course of the semester to insure that the appropriate therapeutic objectives and procedures are being carried out.  Other reports and requirements are discussed under the following sections.

 

THE STAFF

 

         The staff of the Speech and Hearing Clinic is composed of several members of the Communication Department faculty plus student clinicians.  The CSD Program Director is responsible for the curriculum and academic credit and placement, procedures and grades for off-campus practicum (COMD 421).  The Speech Clinic Director is responsible for on-campus clinical scheduling, clinical procedures, awarding grades for COMD 380/381, and documentation of clinical hours obtained during all practicum courses.  The clinical supervisors serve as academic advisors, oversee the completion of the certification requirements, carry out other pertinent clinical tasks, and participate in the Speech and Hearing Clinic operation.

        

         Speech and language evaluations as well as any hearing screenings are carried out by or under the supervision of certified and licensed speech-language pathologists or audiologists.  Speech or hearing therapy sessions are carried out by or supervised by a clinical supervisor.  All reports must have the name, degree, and title of the appropriate supervisor written in the following manner:

CLOCK HOUR REQUIREMENTS

 

ASHA Standard IV-C: The applicant for certification in speech-language pathology must complete a minimum of 400 clock hours of supervised clinical experience in the practice of speech-language pathology. Twenty-five hours must be spent in clinical observation, and 375 hours must be spent in direct client/patient contact (2005).

 

ASHA Standard IV-D: At least 325 of the 400 clock hours must be completed while the applicant is engaged in graduate study in a program accredited in speech-language pathology by the Council on Academic Accreditation in Audiology and Speech-Language Pathology (2005).

 

         The 2005 Standards of the American Speech-Language-Hearing Association (ASHA) require a total of 400 clinical clock hours for certification (upon completion of the graduate degree).  Of that number, 375 hours must be direct client contact, with the remaining 25 hours spent in clinical observation.  The current Standards require observation before direct client contact, however the number of observation hours before a student clinician encounters their first client are no longer specified.  Previously, Harding (and all graduate programs) required all 25 hours of observation before client contact.  Although this is no longer the case, many graduate schools are continuing to require all observation before the initiation of therapy as they transition to the new Standards.  With this in mind, the Harding CSD program is still recommending that each student obtains all 25 observation hours before beginning COMD 380, Clinical Methods and Procedures: Diagnostics.  At least 18 observation hours are required as a part of your academic curriculum (COMD 215, 250, 325, 326, etc.).  You will need to complete additional hours independently.  If you have not completed the 25 hours currently required by some graduate programs, you will be expected to sign a release indicating that you were informed about the current Standards and graduate school expectations.  This form will be distributed as you begin your clinical experiences in COMD 380.

 

         Currently, the Harding University CSD degree requires the completion of approximately 100 clock hours of direct client contact.  Although graduate programs can only accept up to 50 of these hours (see ASHA Standard IV-D), it is the consensus of the Harding CSD faculty that the entire Harding clinical experience will be of benefit in clinical preparation.  Therefore, you will be expected to complete approximately 40 hours of direct client contact while enrolled in COMD 380 and 381, and the remaining 60 hours while enrolled in your off-campus practicum placement (COMD 421).  The Harding University Speech Clinic daily clock hours report form is included in Appendix A.   This form must be completed and submitted at the end of each semester.  A semester summary clock hour form must also be submitted each semester (Appendix B).  This form, when completed, will be added to the hours previously completed and will become a permanent record of clinical experiences at Harding.

         Students must be enrolled in COMD 380, 381, or 421 in order to provide clinical (therapy) services.  The Communication Sciences and Disorders Program provides an off-campus supervised clinic experience semester for CSD majors.  To participate in this experience, students must enroll in COMD 421, Supervised Speech Pathology Practicum.  Placement will be determined based on need, extenuating circumstances, specific requests, etc. Many students will need to commute up to an hour. Each student must complete the placement and the number of available sites is limited.  Therefore, it is the student's responsibility to notify the COMD 421 instructor of any needs in writing well before assignments are made.  Once assignments are made, it will not be possible to change placement locations.

 

ACADEMIC CREDIT IN PRACTICUM

 

         All student clinicians are required to enroll in COMD 380, Clinical Methods and Procedures: Diagnostic or COMD 381, Clinical Methods and Procedures: Treatment for the semesters they are providing therapy in the Clinic.  In addition, each student must also enroll in a lab.  These courses and labs allow each student to receive academic credit for therapy, as well as provide an opportunity for presentation of clinical assessment and intervention procedures.  In addition, COMD 421, Supervised Speech Pathology Practicum and a lab, are required during the off-campus supervised practicum semester.  No student will be allowed to provide therapy services unless enrolled in COMD 380, 381, or 421.

 

 

ENROLLMENT IN PRACTICUM

 

         Before the initial class meeting of COMD 380 or 381, each student clinician is expected to provide a complete class/work schedule that will be used as a guide in assigning clients.  It should be noted that clients would be scheduled according to the information provided by the student clinicians.  Each student clinician is expected to arrange their work and class schedule in such a way that they are available for therapy on at least one of the following: Monday/Wednesday afternoons, Tuesday/Thursday afternoons, or Tuesday/Thursday mornings.

 

         Every student providing clinical services will be required to attend all COMD 380, 381 and 421 class meetings.  This is required.  Special permission must be obtained before missing these classes.  There are no exceptions. 

 

 

THERAPY ASSIGNMENTS

 

         The clinical director will notify student clinicians of cases assigned to them.  A therapy assignment form provides the clinician with the information necessary to begin to plan therapy.

 

         The student clinician must then become familiar with the background information available in the clinic file.  After familiarizing himself with his new clientÕs history, the student clinician should arrange a meeting with the clinical supervisor.  The student clinician should be prepared to discuss the clientÕs disorder and possible courses of action.

 

         The assigned supervisor will provide additional ideas and answer any questions prior to the initial therapy session.  The student clinician will then complete and submit weekly Lesson Plans to the supervisor for approval.  (Specifics and an example are presented in COMD 380 or 381 class presentations, and are discussed in the Lesson Plan section of this document).

 

         Due to the increasing number of student clinicians involved with the Speech Clinic, it may be difficult to provide each with the number of therapy assignments she would like.  If such problems arise, those with fewest clock hours will be given Òfirst optionÓ in order to meet requirements for graduation.

 

 

THERAPY

 

         As therapy is initiated, the clinician must then gather together materials to meet the goals specified in the Lesson Plan.  Therapy materials must always be goal oriented (a concept discussed in your academic courses) and never be used as a time filler.  Enough materials should be readily available to keep the client interested and goal directed throughout the session.

 

         A nice amount of therapy material is available in the supply room in the clinic.  If the clinician is interested in using this he should check it out prior to his/her therapy session and back in immediately afterwards.  ALWAYS RETURN THE CARDS, TESTS, GAMES, AND ETC, TO THEIR PROPER PLACE IMMEDIATELY AFTER THERAPY.  Many of the materials needed for good (or acceptable) therapy sessions will have to be created by the clinician.  This is an aspect of training that will prove valuable in future employment settings.

 

         When the client arrives in the waiting room, the following procedure should be considered as a guide for conduct.

 

1.        At the exact time of the scheduled appointment, the clinician should go to the waiting room, approach the parents, and introduce himself/herself as _(clientÕs name)    Ôs speech clinician.

2.        The clinician should then introduce himself to the client, mention something exciting planned for the session, and as swiftly as possible guide the child to the clinic.

3.        Begin the session by building rapport through simple activities and free conversation.

4.        Get into goal-oriented activities.  Keep the session moving by having plenty of materials readily at hand.

5.        Use the last several minutes for reinforcement activities.

6.        Summarize the session for the parent, and inform her of any homework assignments, in writing.

7.        Remind the parent of the next appointment and say goodbye to the child.

 

If the client is an adult, adapt the above procedures appropriately.

 

 

THERAPY PLANS

 

         Every clinician is required to prepare therapy plans for clients assigned to him.  The Therapy Plan Form is included in Appendix J.  Copies of this form are available online and thoroughly discussed in COMD 380 and 381.  Planning is an extremely important part of a therapy program, and therapy plans should be used as a guide in every therapy session.

         Therapy plans for the upcoming week must be submitted to the clinical supervisor by 12:00pm Friday and a copy will serve as your guide for conducting each session. These plans should include the semester objective along with the goals and procedures to be used during all therapy sessions to be conducted the next week.  It is imperative that each clinician records the objective documentation for each session on their copy after each session.  These therapy progress notes will be submitted to the supervisor along with the therapy plans for the next week.  The student clinician copy is to be placed in the clientÕs working folder and made available to the supervisor during each meeting.  This documentation is used to determine if the client is progressing in a timely manner.

 

         The clinician should refer to these plans often, and at the end of the semester a weekly record of goals, procedures, and progress will exist.  This will be invaluable in completing progress or final reports.

 

         THESE PLANS ARE STRICTLY CONFIDENTIAL.  Client numbers must be used on all plans. They should never be left lying on desks, bookshelves, or tables.  Information pertaining to clients should never be discussed outside of the clinic setting.

 

 

ASSESSMENT AND EVALUATION ASSIGNMENTS

 

         The clinical director schedules all evaluations in the Speech Clinic.  A case history form is usually obtained before an assessment is scheduled.  A draft of the assessment or evaluation report must be submitted to the clinical supervisor within 5 days of the completed assessment procedure.  This draft must be typed and saved on one of the computers in the workroom.  Corrections will be indicated by your supervisor and returned to you for entry in the computer.  When approved, the final draft will be submitted on Harding University letterhead to the clinical supervisor for a signature.  An outline of the subdivisions of such a report is included in Appendix C.

 

         The tests chosen and the order of administration should be determined by information provided on the case history form.  After the clinician is familiar with this form, a meeting with the clinical supervisor should be arranged.  At this meeting, specific tasks will be assigned and planning suggestions will be offered as necessary.

 

 

GETTING UNDERWAY WITH ASSESSMENTS

 

1.    Arrange to conduct the parent interview in the clinic conference room or the therapy room with chairs.  Never conduct the interview in the lobby or waiting room. 

2.    Put the parent Òat easeÓ by making general remarks and chatting, then state the purpose of the interview.

3.    Explain that all information is strictly confidential and will be released only with the parentÕs specific written consent.

4.    Review the case history and ask any questions that will provide valuable information (including preferred name of the child, informant, school problems, and etc.)

5.    Answer any questions concerning services offered.  Have the parents review and sign the therapy enrollment form (Appendix E).

6.    Be relaxed during the interview--a tense and anxious interviewer makes parents uncomfortable.

7.    Do not display emotional reactions to any of the information given, such as shock, horror, embarrassment, anger, etc.

8.    Make sure that the Release of Information Forms have been signed, and ask if our report should be sent to someone.  If so, a Release of Information to an Outside Agency (Appendix F) must be completed.  If another agency such as an assessment team at a childrenÕs hospital has evaluated the client, the parents should complete the Release of Information to Harding Form included in Appendix G.

9.    Explain to the parent what will take place during the assessment.

 

         Since each assessment must be designed with the individual child in mind it would be impossible to present an accurate assessment procedure guide.  However, the following information may prove valuable to the new student clinicians.

 

Articulation

 

         If the parent or referral source expresses concern about sound production the following aspects should be covered.

 

1.    Hearing Screening

2.    Oral Peripheral (Appendix H)

3.    Articulation measure-- possibly one of the following:

         a) Arizona Articulation Proficiency Scale:  Revised

         b) Goldman-Fristoe Articulation Test

         c) Photo Articulation Test

         d)Templin-Darley Articulation Test

4.    A sample of conversational speech (tape recorded)

5.    Basic Language Analysis-- after studying the specific case, one of the following measures may be selected:

         a) Preschool Language Scale, Revised

         b) Peabody Picture Vocabulary Test, Revised

         c) Test for Auditory Comprehension of Language

         d) Utah Test of Language Development

         e) spontaneous language sample

         f) or one of the other language measures available in the clinic.

 

Language

 

         If the referral is based on language concerns, the above format would be followed with the addition of comprehensive language measures.  Note:  An assessment measure should never be used until you are very familiar with administering it.  If you are not familiar with the specific instructions, the test is invalid and a waste of time.

 

         After testing is completed, the clinician and the supervisor should inform the parents or client of the results and basic recommendations.  Every effort should be made to assure that the results and suggestions are fully understood.  Once again, ask if copies of the final report should be supplied to any specific individuals or agencies.

 

EVALUATION REPORTS

 

         An evaluation or assessment report is required for each new client beginning therapy in the clinic.  The reports MUST be typed and saved on the computers in the clinic workroom then turned in to the clinical supervisor within five days of the assessment.

 

         The format of the evaluation report varies slightly for speech and hearing primarily because of the nature of the content of the reports.  An outline of a Speech and/or Language Assessment Report is located in Appendix C.  This outline should be used as a guide but each childÕs assessment report should indicate his individual needs.

 

         All reports must be submitted to the clinical supervisor in accordance with the guidelines previously presented (see Assessment and Evaluation Assignments).

 

 

SEMESTER GOALS & PROGRESS REPORTS

 

         Within one week of beginning therapy with a new client, each clinician is required to submit semester therapy goals to the supervisor.  Each clinician should consult with the supervisor when planning the goals and objectives for the semester.  There are several books available in the clinic to help you in this process including Planning Individualized Speech and Language Intervention Programs by Nelson.  If you are using the suggested goals from the book, you can ask the clinic secretary to photocopy the appropriate pages.  The goals are to be placed in the client's working folder.  It is the responsibility of the clinician to consult with the supervisor during this process.

 

         Throughout the semester, goals that are achieved should be noted in the appropriate space on the goal sheet.  At the conclusion of the semester, or if a client is dismissed from therapy during the semester, all attained goals should be documented and general subjective comments regarding the progression of therapy and recommendations for the following semester should be noted on the goal sheet.  It is the responsibility of the clinician to turn in the goal sheet at the end of the semester to the supervisor.

 

         The recommendations section is a very important part of the progress report.  The clinician should have a conference with the supervisor to discuss this aspect of the report before the report is finalized.  While the clinician is encouraged to suggest recommendations, it should be noted that the supervisor is the final authority.  Clinicians, because of their constant contact with the client, should be able to document the basis for their recommendations.  The supervisor will generally concur with the clinicianÕs view.

 

 

CASE FILES AND RECORDS

 

         Procedures for client records are extremely important and must always be followed carefully.  The clinician is responsible for reporting any missing or incomplete records to the supervisor.

 

         The following procedure is followed for case records:

 

Client file:  When a client contacts or is referred to the clinic, a permanent file is begun and a client number is assigned.  All correspondence, case history forms, etc. are placed in this file.  The clinician assigned to conduct the evaluation or assessment will need to study the file.  If the client is to be actively followed by the clinic, the file will be placed in the active files drawers in the file cabinet in the waiting room.  If the client does not respond to appointments or is dismissed from therapy, the file is placed in Òinactive.Ó 

 

Lesson plan records:  Lesson plans are to remain in the client's working file along with specific notes.  These records are also kept confidential and may not be removed from the clinic.

 

Goals sheet:  Goal sheets are to be placed in the folder within one week of beginning therapy.  Attained goals should be documented as soon as they are achieved.

 

 

TESTS AND ASSESSMENT MATERIALS

 

         Several assessment measures and tests are kept in the supply room.  These are to be checked out by the clinician, if they are taken out of the clinic.  Placing the name of the item, the person removing it, and the time and date removed on the checkout form in the workroom. The test must be returned immediately after use and no later than 8:30 AM the following morning.

 

         Occasionally, a clinician may check out a test for study purposes, but this should be done only with the permission of the supervisor and only on the following conditions:

 

1.   A test may be checked out only after the clinic responsibilities including all assessments and therapy have been completed for the day, usually after 4:30 PM.

2.   Any test must be returned before clinic responsibilities begin on the following morning.  Materials may be checked out following therapy on the Friday before Thanksgiving and after exams before Christmas break, but must be returned on the Monday morning following the break.

 

Permission from the supervisor is necessary in each case.  This checkout procedure applies to test manuals also.

 

         If the clinician plans to use the material for assessment, etc., at a specific time, a note taped to the item (stating the date and time he plans to use it and his name) will alert other clinicians to the fact that the test is needed in the clinic at that particular time.

 

         We have several tape recorders (located in the supervisors offices), picture cards, games, puzzles, blocks, toys, stickers, flashlights, tongue depressors, gloves, hand cleaner, and other supplies that can help make therapy motivation and productive.  You are free to use these supplies as you need them.  Please do not abuse this privilege.  You may never keep any of these materials in your mailbox and prevent other clinicians from having access to them.  You may never ÒhideÓ these materials for your own use, thereby preventing others from using them.

 

         It is important that each clinician become proficient in the operation of equipment commonly employed in speech and hearing work.  Each clinician should also treat each item with care to avoid damage and should report any damage to a clinical supervisor immediately.  You must return all equipment to its proper location immediately after use.

 

 

THERAPY MATERIALS

 

         In addition to the equipment and assessment materials, the clinic also attempts to maintain a basic supply of therapy materials.  Items available include:  Peabody Language Development Kits, Peabody Articulation Cards, Developmental Learning Materials, Game Oriented Activities for Language Kits I and II (GOAL), and miscellaneous toys and stimulus materials.  These kits are very expensive and should be carefully maintained.

 

         Every item must be placed back in the kit after use.  Sometimes a single item lost from a kit can make the rest worthless.  Cooperation by all clinicians will insure longer life of therapy materials and equipment.  This will also permit maximum circulation and application of these items.

 

 

GRADES FOR PRACTICUM COURSES

 

         Factors considered in arriving at a letter grade in practicum courses have been established to provide uniformity in assigning grades to clinicians.  Specific grading forms will be provided and explained in COMD 380, 381 and 421.  These forms will be added to the online manual in the near future.

 

         To elaborate on the points used in evaluating clinicians, the following outline is presented as evaluation criteria.

         Additional points of evaluation-- actually an extension of some of the more important items from the preceding lists-- are presented to further clarify to the clinician what entails quality clinical work.

 

1.   Do children enter and leave the clinic rooms in an orderly manner?

2.   Are children interested in their work?

3.   Do children slouch on chairs and the table?

4.   Does the clinician deal in a kind, firm, and impartial manner with the children?

5.   Does the clinician talk to the children as though they were his equal?

6.   Does the clinician provide constructive activity for the child who wants to dominate, especially in group therapy?

7.   Does the clinician encourage the retiring child?

8.   Does the clinician introduce visitors (observers or supervisors present in the observation room) to the client?

9.   Does the clinician avoid discussing the clientÕs speech difficulties in the clientÕs presence?

10. Does work provide variety in group therapy according to the needs of individual members?

11. Are devices adapted to the age and speech development of the client?

12. Are speech activities correlated with activities in the classroom, playground, and          home?

13. Does the clinician talk too much?

14. Is the work planned so that each client gets sufficient opportunity to practice his ÒgoodÓ sound in group situations?

15.
