Compatible with most developmental curricula, CSBS DP™ is an easy-to-use, norm-referenced screening and evaluation tool that addresses communicative behavior and symbolic development. Derived from the popular, norm-referenced CSBS™, CSBS DP™ is shorter, faster, and lets you begin identification earlier. It’s an ideal starting point for planning IFSPs, determining the efficacy of interventions, documenting changes in a child’s behavior over time, and identifying areas for further assessment.
