1. Interpretation During today’s evaluation, we used the Preschool Language Scale- Fifth Edition (PLS-5) and general observations of the way Z plays and interacts with others to assess her speech and language skills. The PLS-5 is a norm-referenced test, meaning that the creators of the test developed a set of “typical” or “average” scores based on a large sample of children, to help clinician’s determine whether a child, like Z, performs at the same level as other children her age that were included in the sample. a. The PLS-5 looks at a few things that help us to determine Z’s speech and language abilities. One area that the test pinpoints is called auditory comprehension– this refers to things such as Z’s attention to her environment…show more content…
Z’s score fell in the 1st percentile in both auditory comprehension and expressive communication. What this means is that Z scored as well or better than 1% of the sample population of children her age, but 99% of other children her age achieved a higher score. e. Age-equivalent scores represent the average score of the children in the sample for a particular age group in a specific area. For example, Z got an age equivalent score of 7-months for auditory comprehension. This does not mean that Z understand language at a 7-month-old level, but rather that Z’s score corresponds to the average raw score obtained by 7-month-olds in the PLS-5 sample. On the expressive communication section, Z’s score translated to an age equivalency of 5-months, meaning that her raw score corresponds to the average raw score obtained by 5-month-olds in the PLS-5 sample. These scores try to compare children to the “average” X-year-old, but language development is remarkably variable and the “average” child does not really exist. We like to look as “average” as more of a range, rather than a set level of achievement. 2. Short-term Session goals: a. Given a field of 5 objects out of her reach and vocal/gestural modeling by the clinician and parent, Z will increase frequency of intentional communication, using signs, gestures or vocalizations to request desired object in 8 out of
