The Woodcock-Johnson® IV Tests of Achievement (WJ IV™ ACH) includes three forms of the eleven tests in the Standard Battery (Forms A, B, and C).
Alternate forms are useful for repeated testing of the same individual over time to measure progress or change over time.
By using a different, but equivalent, form for each administration, professionals can reduce dependence on any single form of the test and minimize potential overexposure to the test items.
To review further information regarding the alternate forms of the WJ IV™ ACH, please see our Assessment Service Bulletin below:
