The Woodcock-Johnson IV Tests of Cognitive Abilities are a comprehensive battery of standardised assessments designed to evaluate a wide range of cognitive abilities in individuals of all ages (2-90 years). The tests measure verbal and nonverbal abilities, including memory, reasoning, phonological awareness and problem-solving skills. They are often used to assess cognitive strengths and weaknesses, identify learning disabilities, and monitor progress in educational or therapeutic settings. They are considered reliable and valid measures of cognitive abilities and are widely used in both academic and clinical settings.

Examiners will enjoy administrative flexibility and interpretive clarity with the WJ IV Tests of Cognitive Abilities alone; however, combining administrations of the co-normed WJ IV Tests of Achievement and Tests of Oral Language will increase diagnostic capability and sensitivity.

Scoring and Reporting

All Woodcock-Johnson IV Tests are paper-based assessments with digital scoring and reporting tools available on the Riverside Score platform. Riverside Score is a secure, web-based platform where examiners can quickly enter raw scores, assessment data and test observations. In addition, various reports suitable for parents, teachers and other professionals can be generated instantly on the platform.
