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

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

This report documents the results of an item parameter drift study designed to check the parameter stability of MAP Growth items.

Two studies were conducted to evaluate whether the existing MAP Growth item parameter estimates are invariant across different calibration samples.

This document presents the test design and specifications for Spanish MAP Reading Fluency.

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 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.
