National Center for Research on Evaluation, Standards, and Student Testing

For over 40 years, the National Center for Research on Evaluation, Standards, and Student Testing (CRESST), and its home organization, the UCLA Center for the Study of Evaluation, has been a leading research organization committed to the design and use of evaluation to improve educational programs. Originally established in 1966 as the result of a national competition, the status of CRESST as the national center for research in its mission area has been continuously reaffirmed through repeated competitions.

Throughout its history, CRESST has concentrated on fundamental issues in educational policy and practice. These include:

  • What is the quality of student learning?
  • What are the effects of educational programs and practices?
  • How can assessment and evaluation methodologies be improved to provide more valid data for educational decision-making?
  • How can policymakers and practitioners be helped to utilize the best of evaluation theory and research and to use evaluation to leverage and support educational improvement?


How CRESST Supports Implementation of LDC Tools

CRESST has been engaged in the evaluation of the implementation and impact of LDC tools since June 2011, with funding from the Bill and Melinda Gates Foundation. Two independent studies of LDC have been completed: one examining LDC implementation in 8th grade social studies and science classrooms in Kentucky and Pennsylvania, and the second an examination of district-wide implementation in 6th grade advanced reading classes in Hillsborough County, Florida. The studies employed specially crafted measures of LDC implementation and impact and featured a quasi-experimental design to examine LDC impact on student learning.

CRESST is the independent evaluator for’s i3 validation grant.. This study is using rigorous design and mixed-methods to document the impact of LDC on student learning, as well as on teacher skills and practices. CRESST brings to the effort strong capacity in rigorous qualitative and quantitative methodologies and wide experience in evaluating and supporting the improvement of state, district, and local programs. will benefit from having an evaluator with deep understanding of its intervention goals and strategies and access to a wide range of LDC evaluation tools and instruments that can be easily augmented to fit the focus of the current i3 validation study.
