Woodcock-Johnson IV

The Woodcock-Johnson IV® (WJ IV)

A comprehensive assessment system on the cutting edge of clinical practice.

The Woodcock-Johnson IV (WJ IV) is structured to offer the ease of use and flexibility that examiners need to accurately evaluate learning problems for children and adults in a way that no other assessment solution can.

  • Facilitate exploration of strengths and weaknesses across cognitive, oral language, and academic abilities
  • Batteries can be used in conjunction with one another or as standalone assessments
  • Clusters engineered to provide the most diagnostically useful interpretations
  • Simplified and reframed procedures for evaluating ability/achievement comparisons and intra-ability variations
  • Expanded focus beyond the original broad CHC
    theory that was the foundation for the WJ III®

Woodcock-Johnson IV Batteries and Options

WJ IV Tests of Achievement

Restriction Level: Medium Ages: 2 - 90+ Time Per Subtest: 5 - 10 mins

The Woodcock-Johnson IV Tests of Achievement (WJ IV ACH) are ideal for accurately screening, diagnosing, and monitoring progress in reading, writing, and mathematics achievement with the 11-test standard battery.

The nine-test extended battery allows for a more in-depth diagnostic assessment of specific strengths and weaknesses.

  • Selective testing: administer only the tests relevant to your referral questions
  • Monitor progress once a proficiency level is established and interventions are implemented
  • Parallel forms prevent examinees from building familiarity with test content

The WJ IV Tests of Cognitive Abilities

Restriction Level: High Ages: 2 - 90+ Time Per Subtest: 5 - 10 mins

The Woodcock-Johnson IV Tests of Cognitive Abilities (WJ IV COG) contain the greatest breadth of cognitive abilities of any standardized body of tests. New tests and clusters have been designed to place emphasis on the most useful measures for identifying individuals’ patterns of strengths and weaknesses.

Understanding relative strengths and weaknesses in comparison with the Gf-Gc Composite can lead to individualized instruction designed to target identified learning needs.
  • New Gf-Gc Composite for comparison with other cognitive, oral, and achievement measures
  • All-new working memory, perceptual speed, and phonological processing measures
  • Easy-to-use intracognitive variation procedure allows documentation of cognitive strengths and weaknesses

The WJ IV Tests of Oral Language

Restriction Level: Medium Ages: 2 - 90+ Time Per Subtest: 5 - 10 mins

The Woodcock-Johnson IV Tests of Oral Language (WJ IV OL) can be used to determine and describe an individual’s strengths and weaknesses with regard to expressive language. The
12-test battery consists of nine English tests and three Spanish tests.

The three parallel Spanish tests (Picture Vocabulary, Oral Comprehension, and Understanding Directions) can give teachers a better understanding of the individual’s language abilities in order to make more informed educational placement and instructional decisions.
  • Use independently or in conjunction with the Tests of Achievement / Cognitive Abilities
  • Three parallel Spanish tests help classify language proficiency and ability
  • Compare proficiency on English- and Spanish-language tasks through the Comparative Language Index (CLI)

The Woodcock-Johnson IV Tests of Early Cognitive
and Academic Development (ECAD®)

Restriction Level: High Ages: 2:6 through 7:11 Time Per Subtest: 5 - 10 mins

One easel, one test record, one hour. That’s all it takes for a complete administration of the Woodcock-Johnson IV Tests of Early Cognitive and Academic Development (ECAD®). For examiners with specific referrals, it could take even less.

ECAD features a combination of unique new material and early-form content adapted from trusted Woodcock-Johnson IV tests, offering a dynamic way for examiners to assess emerging cognitive abilities and academic skills in young children and children with cognitive delays using contemporary, theory-based measures.

  • One easel, ten tests: 4 unique to ECAD, and 6 early forms of WJ IV materials
  • Complete assessment clusters for ECAD individually or in any combination
  • Report percent delay, standard deviation delay, and months delay scores

The WJ IV Interpretation and Instructional
Interventions Program™ (WIIIP®)

While no tool can replace an examiner's training, experience, and intuition, a WIIIP subscription offers a research-based supplement that can serve as a starting point for analysis, discussion, and implementation of teaching strategy, generating personalized interventions and accommodations based on an individual’s Woodcock-Johnson® IV and ECAD results.


  • Reason for Referral Checklist
  • Parent’s Checklist: School Age
  • Teacher’s Checklist: School Age
  • Parent’s Checklist: Preschool Age
  • Teacher’s Checklist: Preschool Age
  • Classroom Behavior Observation Form
  • Self-Report Checklist: Adolescent/Adult
  • Writing Evaluation Scale

WIIIP Comprehensive Reports for WJ IV & ECAD

WIIIP Comprehensive Reports provide actionable steps for schools and practitioners working on problem-solving teams, and can serve as an ideal solution for implementing discrepancy models or Response to Intervention (RtI) processes.

WIIIP Dyslexia Report for WJ IV

Available only with a WIIIP subscription, the new WJ IV Dyslexia Report provides a conceptual framework for the evaluation of dyslexia. It also:

    • Contains new dyslexia evaluation checklists that aids in diagnostic decision making and intervention planning
    • Organizes and presents assessment results in a manner useful for determining whether students are demonstrating dyslexia characteristics
    • Assists school teams with program eligibility-decisions

The Dyslexia Report includes formative and evidence-based interventions tied to the examinee’s unique test results and can be used with other WIIIP checklists to provide a comprehensive profile of an examinee’s abilities.

Scoring and Reporting

All Woodcock-Johnson IV and ECAD scoring is completed in the Riverside Score system.

Riverside Score provides a secure, web-based environment where examiners can easily enter raw scores, assessment data, and test session observations for any of the assessments listed below.

After entering data, examiners can generate reports for all derived scores and clusters. Reports can be viewed online or downloaded as PDFs, Word documents, or HTML files for easy sharing and offline review.
