Desired Results Developmental Profile (DRDP) for 2015: Fulfilling the Vision for Early-Childhood Assessment in California, Illinois, and Beyond
The California Department of Education’s Desired Results Developmental Profile (DRDP) assessment program provides valid and reliable psychometric measurement in the key domains of child development, early infancy through kindergarten, based on teachers’ observations of the children in their care. From its original form implemented in 2000, DRDP has gone through two complete rounds of revision, to update and refine assessment content and properties of measurement, and is currently undergoing a third round. The result of the latest revisions will be DRDP (2015). This talk will review
- Methodology used by BEAR Center researchers to develop and refine DRDP, in collaboration with project partners including a broad range of state government officials, university research faculty, and practitioners in early-childhood education
- DRDP’s developmental domains of measurement and the new dimensionality structure that will allow for the first time with DRDP (2015) children to be measured on developmental domains, and also separately on nested hierarchical sub-domains
- Psychometric models and data-structural techniques used to calibrate domain and sub-domain scales of measurement that are equated across the entire age range covered by DRDP (2015)
- Sampling issues encountered in this work, and the design solutions used to support domain scale calibrations.
