ARTICULATION AND PHONOLOGY VIDEO ASSESSMENT TOOL

NAME

Articulation and Phonology VAT

■ Authors: Adriana Lavi, PhD, CCC-SLP and Cristina Gamarnik, MS, CCC-SLP

■ Published in: 2020

Purpose

■ This assessment tool is designed to assess children and young adults who have been previously diagnosed or are suspected of having a speech sound disorder.

■ Aides in the identification of an articulation or phonological disorder.

Age range

■ Assessment is for children and young adults age 2-21.

■ The test is broken into three versions based on age. Separate video tests are used for age groups 2:0-2:11, 3:0-5:11, and 6:0-21 years old.

Standardization

■ The Articulation and Phonology Video Assessment Tool normative data is based on the test performance of 1,035 typically developing examinees whose ages range from 3;0 to 21;0.

■ The data was collected throughout the 2017-2020 school-years by 36 state licensed speech-language pathologists.

■ To ensure representation of the national population, the sample was stratified within each age group by the following criteria: gender, race or ethnic group and geographic region.

Personal Critique: The sample included children who were from different ethnic groups and geographic regions, but since the sample was selected to match the US Census data, those clients representing minority groups have been underrepresented.

Who can administer the Articulation and Phonology VAT? ■ Professionals who are: – properly trained in the ethical administration, scoring, and interpretation of

standardized assessment tools. – who hold appropriate educational and professional credentials. ■ Qualified examiners include: ■ speech-language pathologists ■ school psychologists ■ special education diagnosticians ■ Other professionals representing closely related fields.

Administration

■ The Articulation and Phonology VAT can be accessed online. The test and the associated converting software are available on the Video Assessment Tools website.

■ Administration time for the assessment takes approximately 25-30 minutes. ■ Administered from a laptop/desktop or tablet. ■ The video-based assessment tool is composed of short video segments

focusing on 45-55 target words. Sounds are located across all positions in initial, medial, and final position of words. Vowels are also assessed.

Administration procedures

■ Begin by logging onto your Video Assessment Tools account at www.videoassessmenttools.com and select the “Administer now” tab to load the Articulation and Phonology VAT. Make sure the test you select corresponds with the client’s age range.

■ Once the assessment loads, there will be two viewing options available. Both options contain the same videos and test items therefore, you choose the option you prefer.

■ Begin administering the test by giving the client an overview of what will be taking place.

■ Start with the practice item. On the protocol, circle each sound that is produced incorrectly.

Administration Procedures ■ Once the assessment is complete, select the “Get Raw Scores” tab that corresponds

to the testing age range. The Articulation/Phonology Scoring Sheet is completed online. You will record all articulation errors and comment yes/no as to whether there were any phonological errors observed.

■ Next, select the “Get Standard Scores” from the side toolbar. You will enter the student’s raw score and age which will give you a standard score and percentile rank.

■ Lastly, there is an optional report generator to assist you in writing the articulation and phonology write-up portion of the evaluation.

Personal Critique: The administration of the test is straightforward and not very time consuming which could be great for clinicians who are extremely busy. Since the test is administered virtually, clients may feel more comfortable completing the assessment. The Articulation and Phonology VAT is designed for students who are native speakers of English and/or are English language learners. Students who were native English speakers and also spoke a second language were also included. There is no mention of modifications for culturally and linguistically different clients.

Recording/Scoring procedures ■ The clinician listens carefully to the production of each word and records any

distortion, substitution, omission, or lisp of the targeted sounds. ■ The clinician also makes note of any phonological process, such as stopping,

fronting, initial consonant deletion, or gliding.  ■ The assessment yields a raw score, standard score, percentile rank, interpretation

value, and test-age equivalent. ■ The clinician can complete the protocol online or print the PDF to have a hardcopy,

and then transfer the results to the “Raw Score” page on the assessment website. The raw scores can then be converted automatically to standard scores, which will also reveal a percentile rank.

■ There are no modifications listed for culturally and linguistically different clients. 


Interpretation/analysis

■ The results of the Articulation and Phonology VAT provide comprehensive information on articulatory and phonological skills of children and young adults. By using this assessment tool, clinicians can develop a better understanding of how a client’s articulation and phonology production can effect their academic performance in school.

Personal critique

■ The Articulation and Phonology VAT is a brief and convenient measure of articulation and phonology. The assessment was developed and validated for telepractice which can benefit many clinicians and their clients who may be too busy to come into the clinic for assessment. There are three versions of the test for each age group which I feel will aid in participation and awareness. Although there were no modifications listed for culturally and linguistically different clients, the normative sample included children from various ethnic groups and geographic regions.
