The Center for Research on Evaluation, Standards, and Student Testing (CRESST) is a respected leader in assessment design, evaluation, implementation, scoring, and standards.

CRESST has partnered with ELPA21 from its inception and continues to provide guidance and leadership that contributes to the innovation and enhancement of ELPA21’s assessment systems.

Technical Advisory Committee

ELPA21 leverages the collective knowledge and guidance of a technical advisory committee (TAC). The TAC acts in an advisory capacity in a variety of critical areas including assessment design, psychometrics and test validity, implementation, hardware and software requirements, and applications that affect design and development. The TAC responds to challenges and develops solutions to tough questions.

Assessment delivery experts

ELPA21 calls on a number of expert partners to create the best possible assessment delivery systems.

The initiative aims to heighten educator awareness of the critical role language plays in the new Common Core State Standards and Next Generation Science Standards.

A collaborative governance system

ELPA21 is committed to a collaborative model. Our governance and management structures rely heavily on the collective wisdom and decisions of ELPA21 members. Each member has a voting representative on ELPA21’s Governing Board, which oversees the strategic plans behind the operation and growth of ELPA21.

Advisory committees provide guidance and reviews of the processes and projects within ELPA21. Each advisory committee includes member-nominated participants. The committees are Research and Evaluation, Assessment Design, and Member Support and Outreach.
