This page contains the reference tables used to determine student eligibility under the Specific Learning Disability category.
These tables are used by district evaluators and
others who perform diagnostic evaluations as part of the identification
process for special education. If you have questions regarding the
reference tables on this page, please contact Robert Meacham at firstname.lastname@example.org (502) 564-4970.
are now available for the following instruments and their pairings:
WISC-V, KTEA-3 and WJ-IV. Test pairings previously published may not be
available for updated test editions simply because comparative studies
between many instruments that took place in the past were not conducted
for tests updated in the fall of 2014. For example, pairings between the
WISC-V and WJ-IV Achievement, and WJ-IV Cognitive and KTEA-3 are not
part of the update as current correlative data for these tests are not
yet, nor are they anticipated to be made available. Districts may
continue using older pairings that were included in this update and
published on this site through December 2015. Districts that use the
Stanford Binet 5 and the Universal Nonverbal Intelligence Test for LD
identification will NOT have pairings beginning in January 2016.
How to use the Discrepancy Tables
LD Tables Update - Interim Decision Making Letter This letter explains why changes have taken place with the 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.
The L.D. Advisory Group recommends a minimum 14 point difference between the Verbal and Non-Verbal IQs on the Stanford-Binet
5 before considering the higher of the two scores as the best measure
to be used in determining an aptitude/achievement discrepancy.
