What is the WJ IV?
The Woodcock-Johnson IV Tests of Achievement (WJ IV) is a test commonly used by psychologists to determine a person’s academic strengths and weaknesses. The WJ-IV is made up of several subtests that measure a person’s reading, writing, and math skills.
The WJ IV is made up of 20 subtests that make up six broader clusters including reading, writing, math, science, social studies, and the humanities and takes about 60-90 minutes to administer. The WJ IV can be used with individuals from preschool age through adulthood, though it is most commonly given to school-aged children and adolescents. The WJ IV gives standard scores (similar to IQ scores), age equivalents, and grade equivalents to help interpret performance.
What is the WJ IV used for?
Results from the WJ IV 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 IV can be extremely helpful in developing Individual Education Plans (IEPs) for students and in determining any learning difficulties or learning disabilities. The WJ IV can also be helpful in determining whether children are eligible for any special services as defined by the Individuals with Disabilities Education Act (IDEA).
