The Woodcock-Johnson III (WJ III) consists of two distinct, co-normed batteries: 

• The WJ III Tests of Achievement
• The WJ III Tests of Cognitive Abilities

Together, these batteries comprise a wide age-range, comprehensive system for measuring general intellectual ability (g), specific cognitive abilities, scholastic aptitude, oral language, and achievement.

Normative data are based on a single sample that was administered both the cognitive and the achievement tests.  This important feature creates a highly accurate and valid diagnostic system for evaluating domain-specific skills with related cognitive abilities as well as traditional ability/achievement discrepancies.

Woodcock-Johnson III (WJ III) Tests of Cognitive Abilities

The WJ III Tests of Cognitive Abilities is based on the Cattell-Horn-Carroll (CHC) theory of cognitive abilities, which combines Cattell and Horn's theory and Carroll's three-stratum theory.  The CHC theory provides the most comprehensive framework available for understanding the structure of human cognitive abilities.

The Standard Battery consists of tests 1 through 10, and the Extended Battery includes tests 11 through 20.  Depending on the purpose and extent of the assessment, examiners can use the Standard Battery alone or in conjunction with the Extended Battery.

Woodcock-Johnson III (WJ III) Tests of Achievement

The WJ III Tests of Achievement is divided into two batteries – Standard and Extended.  The Standard Battery includes tests 1 through 12 that provide a broad set of scores.  The 10 tests in the Extended Battery provide more in-depth diagnostic information on specific academic strengths and weaknesses.  Examiners can administer the Standard Battery either alone or with the Extended Battery.

 The WJ III Cognitive Abilities and Achievement Test Batteries offer clinicians a toolbox of tests for use in the assessment of individuals.  Clinicians can refer to the Selective Testing Table and administer the sub-tests indicated to obtain diagnostic results for specific factor and cluster scores required, ensuring efficient use of testing time.

Woodcock-Johnson III (WJ III) Complete Battery of Tests

The WJ III Complete Kit contains both the Cognitive Abilities and Achievement Test Batteries and provides clinicians with a comprehensive assessment system for testing individuals aged 2 years to 90 years.

This cost-effective battery will provide you with valuable diagnostic information for students with a wide range of educational difficulties, as well as for the gifted and talented.

WJ III Compuscore Scoring & Profiles Program - Australian Adaptation

TheWJ-III NU Compuscore Scoring & Profiles Program is provided upon purchase of the WJ III Complete Battery, WJ III Cognitive Battery and the WJ III Achievement Battery.

The Australian Adaptation of the WJ III Compuscore Scoring & Profiles Program - Compuscore (AA) - is now available to download for anyone who has the software installed on their computer. Download Compuscore (AA) here.

Woodcock Interpretation & Instructional Interventions Program (WIIIP)

The WIIIP expands on benefits offered by the WJ III NU Compuscore and Profiles Program to provide a complete assessment and intervention software program.

• Quickly score your Woodcock assessments.
• Integrate information from checklists and multiple measures.
• Prescribe academic interventions based on test results.
• Generate comprehensive reports.

The WIIIP allows you to customise your reports with the evidence-based instructional interventions WIIIP recommends. The list of interventions provided for each individual is completely customized based on his or her scores.

There are seven reports avaible:

• Comprehensive Report (Australian Norms)
• Score Report (USA Norms)
• Summary and Score Report (USA Norms)
• Comprehensive Report (USA Norms)
• Age/Grade Profiles (USA Norms)
• Standard Score/Percentile Rank Profiles (USA Norms)
• Proficiency Profile Report (USA Norms)
• Diagnostic Worksheet (USA Norms)

The Australian Adaptation of the WIIIP - WIIIP (AA) - is now available to download for anyone who has the WIIIP software installed on their computer. Download WIIIP (AA) here.

WJ III Clinical Use and Interpretation

WJ III Clinical Use and Interpretation discusses clinical and academic applications of the WJ III with respect to specific populations and presents research findings on the reliability and validity of the test. The book also provides methods to aid in the understanding and interpretation of WJ III results for various groups of average and exceptional children.
