The purpose of this research report is to provide detailed information about updates to the MAP Growth item-selection algorithm. This brief includes results from the Content Proximity pilot study, including information on the validity, reliability, and test score comparability of MAP Growth assessments that leverage this new item-selection algorithm.

The MAP Growth theory of action describes key features of MAP Growth and its position in a comprehensive assessment system.

Approaches to test score use and test purpose lack the well-developed methodological guidelines and established sources of evidence available for intended score interpretation. We argue in this paper that this lack fails to reflect the ultimate purpose of a test score—to help solve an important problem faced by intended test users.

This technical report documents the processes and procedures employed by NWEA to build and support the Spanish MAP Growth Reading assessment.

This report presents the results of a mode comparability study conducted through simulations to evaluate how scores from MAP Growth administered on the constraint-based engine (CBE) compare to those administered on the current MAP Growth engine known as COLO.

The purpose of this literature review is to study the advantages and limitations of various through-course summative assessment models with the goal of informing the design of the NWEA through-year solution.
