RESEARCHThe following charts represent the percentile gains (converted from standard scores) made by our students on standardized tests. The median percentile is the 50th. Generally, the average range is from the 25th to the 75th percentile.
To remain as current as possible, we update our diagnostic materials as revisions are made to the tests. For the students that begin with an older version of a test, they are retested on the newest version of the test available at the time. Consequently, the data in some of these graphs includes some students who had pretest scores from the previous test versions. By comparing standard scores rather than raw scores, the amount of growth should be comparable. |
Private Clinic Research Results
The graph below illustrates research results from January 2015 through June 2024 for our private clinic students. The section in grey delineates the average range. Following that are the research results for each specific area of assessment.

TREATMENT TIME
The majority of our private clinic students attend one-hour sessions five days per week. The average time in treatment for our students is 120 to 160 hours. Some students attend intensively for two to four hours per day, and some attend for enhancement of their skills for 40 to 80 hours. Others return to the clinic for brief refreshers for several weeks or months. Individuals with severe disabilities may attend for a year or more.
SAMPLE SIZE
The sample size fluctuates on each graph based on the program or programs received. In addition, not all students receive all of the tests during their retesting. For instance, if a student has performed well on their initial diagnostic testing on a particular test, they are generally not tested again on this measure. This also impacts the number of students included in the graph data.
