The Kaufman Test of Educational Achievement, Third Edition (KTEA-3) is a revised and updated comprehensive academic achievement test (Kaufman & Kaufman, 2014). Authored by Drs. Alan and Nadeen Kaufman and published by Pearson, the KTEA-3 remains an individual achievement test normed for individuals of ages 4 through 25 years, or for those in grades prekindergarten (PK) through 12 and above. Based on a clinical model of academic skills assessment in the broad areas of reading, mathematics, and written and oral language, the KTEA-3 follows the Cattell-Horn-Carroll (CHC) or Information Processing theoretical assessment approach. Detailed information regarding the composites' structure and rationale for changes to subtest inclusion and/or exclusion is provided. Updates assess learning disabilities according to the Individuals With Disabilities Education Improvement Act (IDEIA; 2004) or the "Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-V; American Psychiatric Association" [APA], 2013) criteria. Norm-referenced for diagnostic and classification purposes, the KTEA-3 offers criterion-referenced pattern analyses of errors or individual strengths and weaknesses to facilitate intervention planning. The most recent addition to the Kaufman series, the KTEA-3, described here is a revision of their broad-based academic skills assessment, yielding three core academic composites and 10 supplemental composites.
