WJ IV™ Tests of Early Cognitive and Academic Development (ECAD™), a groundbreaking early childhood assessment which combines 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.

Featuring artwork and expanded content specifically designed to maximize appeal and usability for all children ages 2:6 through 7:11, and children with cognitive developmental delays through ages 9:11, the ten-test ECAD battery measures general intellectual ability, early academic skills, and expressive language skills—all in a single test easel.
