What is the WJ III?
The Woodcock-Johnson III Tests of Achievement (WJ III) is a test commonly used by psychologists to determine a person’s academic strengths and weaknesses. The WJ-III is made up of several subtests that measure a person’s reading, writing, and mathematic skills.
The WJ III is made up of 22 subtests that make up five broader clusters including reading, oral language, written language, math, and academic knowledge and takes about 60-90 minutes to administer. The WJ III can be used with individuals from preschool age through adulthood, though it is most commonly given to school-aged children and adolescents. The WJ III gives standard scores (similar to IQ scores), age equivalents, and grade equivalents to help interpret performance.
What is the WJ III used for?
Results from the WJ III are helpful in determining where students should be placed in academic programs or if any accommodations would be helpful to them. Results from the WJ III can be extremely helpful in developing Individual Education Plans (IEPs) for students and in determining any learning difficulties or learning disabilities. The WJ III can also be helpful in determining whether children are eligible for any special services as defined by the Individuals with Disabilities Education Act (IDEA).
