The DEAP is commonly used in conjunction with an additional assessment tool, such as the CELF-4 or other language tests in order for the Speech-Language Pathologist to have a clear understanding of the child's speech and language functioning.

Standardization Sample
Who?
The standardization and related validity and reliability research for DEAP occurred in March 2005 and continued through October 2005. It involved over 650 children between the ages of 3 years, 0 months through 8 years, 11 months. The sample, based on the 2003 U.S. Census was stratified on the basis of age, race/ethnicity, geographic region, and parent education level. N=650 based on the current population.
Our Thoughts on the DEAP
Our Thoughts
- The bright and colorful pictures used in the assessment are great for keeping the child's attention.
- The short duration of the assessment is helpful because of the generally short attention span of children.
- Overall an effective and beneficial screening and assessment tool.
