This page contains the reference tables used to determine student eligibility under the Specific Learning Disability category. The information is supported by the regulation 707 KAR 1:310 Determination of eligibility.
These tables are used by district evaluators and others who perform diagnostic evaluations as part of the identification process for special education.
Updates are now available for the KABC-II NU. As previously noted on this site, prior test pairing may not be available for updated test editions because comparative studies between many instruments that took place in the past have not been replicated.
How to use the Discrepancy Tables
The following links include the pairs of aptitude and achievement tests that might be used in calculating an aptitude-achievement discrepancy using the Regression Estimated True Score Method.
For each test pairing, the age level and table reference is provided. For example, the line looks like the information below:
Apt Test Achievement Test Pairing Age Table/Col
WISC-V FS KTEA III Math Computation 6 2-E
In this pairing the WISC-V Full Scale IQ score and KTEA-III Math Computation score would be used. For a student age 6, the appropriate table of criterion values would be Table 2. In Table 2 the user would locate the criterion value in Column E that corresponds to the student’s WISC-V Full Scale IQ score. This criterion value would then be compared to the student’s achievement score on the KTEA-III Math Computation score test.
Current Test Pairings
Calculated WISC-V Guidance Please note, this guidance has significantly changed. Please read the Calculated WISC V Guidance document before calculating GAI discrepancies. The publisher recommends only the WISC Full Scale be used for SLD pairings.
