Assess general intellectual ability, academic skills, and oral expression in your earliest learners.

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 be even less. 

ECAD measures general intellectual ability, early academic skills and oral expression in all children ages 2:6 through 7:11 and children with cognitive developmental delays through age 9:11.


With its combination of unique new material and early-form
content adapted from trusted WJ IV tests, ECAD provides 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.

 

The 10 ECAD tests -- 4 unique and 6 early forms of WJ IV material -- are all included in one easel. Tests adapted from existing WJ IV content include Sentence Repetition, Sound Blending, Rapid Picture Naming, Picture Vocabulary, Letter-Word Identification, and Writing.

 

Assessment clusters for ECAD can be completed individually or in any combination. Plus, some tests provide information applicable to multiple clusters, providing examiners with even more options for test customization. ECAD offers percent delay, standard deviation delay and months delay scores, helping assessors in many states meet IDEA eligibility requirements.

 

For detailed information on testing and clusters, check out the Selective Testing Table below!

Use ECAD to...

  • Measure general early intellectual ability, early academic skills, and early expressive language skills 

  • Complete a full psycho-educational assessment of younger children not possible or not ideal with other assessments

  • Generate percent delay, standard deviation delay and
    months delay score reports to meet IDEA eligibility
    requirements 

Restriction Level

 

Medium

Testing Ages

ECAD is designed for use with examinees ages 2:6 - 7:11, and is valid up to age 9:11 when a cognitive delay is present.

Time to Test

A typical administration requires 5 - 10 minutes per subtest.

Sample Standard Reports

ECAD assessment results are calculated in real time through a streamlined, web-based scoring and reporting platform that's accessible for free* from any computer with an Internet connection.

 

To determine the presence and severity of cognitive delays, ECAD offers percent delay, standard deviation delay, and months delay scores, helping assessors in many states meet IDEA eligibility requirements.

 

The Score Report provides age equivalent (AE) scores (including difficulty levels or ranges), relative proficiency index (RPI), and standard score or percentile rank for a single examinee.

 

The Parent Report describes the clusters or tests administered and provides a profile of the examinee’s norm-based or criterion-referenced based proficiency when compared with others of the same age nationally. This report is available in English and Spanish.

 

The Profile Report provides a graphical description of the examinee’s performance using the standard score confidence band and percentile rank (PR).
