I authored the Mac OSX, Windows and web versions of the Woodcock–Johnson IV ECAD test system in 2014 and 2015. The application includes video instructions and a automatic scoring functionality on all platforms.

The Woodcock–Johnson IV (WJ IV) Tests of Early Cognitive and Academic Development (ECAD) is a special-purpose early childhood battery of cognitive and academic skills tests that is co-normed with, and conceptually related to, the Woodcock–Johnson IV. The ECAD measures emergent cognitive abilities and academic skills. It is designed primarily for use with children from 30 months through 7 years of age, although the battery is also appropriate for use with children ages 8 through 9 years who have cognitive-developmental delays or intellectual disability. Testing materials required for administration of the ECAD include the test book, test record, and response worksheet; the audio CD and appropriate audio equipment; pencils; and a stopwatch. The ECAD can be interpreted at the test and cluster levels, depending on the purposes of an evaluation. The Early Academic Skills cluster is an aggregate measure of emergent or developing reading, math, and writing skills. The Early Academic Skills cluster can also be useful as a screening measure for any delay in the development of early academic skills. The ECAD introduces a set of terms to describe a child's levels of cognitive and academic development.
