This study evaluates the performance of Pychometrik, a new item calibration tool, against the existing tool for MAP Growth.

The report documents the process NWEA followed to determine and validate the cut scores for fall, winter, and spring that can be used to identify students in Grades K–8 who have severe learning difficulties and need intensive intervention in reading and mathematics.

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.

This report presents the results of a mode comparability study conducted based on empirical data 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 calibration study was conducted to investigate the consequences of replacing the English MAP Growth Mathematics item parameters with the Spanish mathematics item parameters.

This is a follow-up analysis to the May 2019 item fit analysis study to evaluate the fit of the items whose item difficulties were adjusted in the more recent 2020 follow-up scale alignment study.

NWEA equated words-correct-per-minute (WCPM) scores from oral reading passages included in the NWEA MAP Reading Fluency assessment.
