This report documents the procedure used to produce the achievement and growth user norms for a series of the course-specific MAP® Growth™ subject tests, including Algebra 1, Geometry, Algebra 2, Integrated Math I, Integrated Math II, Integrated Math III, and Biology/Life Science. Among these tests, Integrated Math I, Integrated Math II, Integrated Math III, and Biology/Life Science were the first time to have their norms available. The remaining tests, i.e., Algebra 1, Geometry, and Algebra 2, had their norms updated including receiving more between-term growth norms by using more recent test events. Procedure for norm sample selection and a model-based approach using the multivariate true score model (Thum & He, 2019) that factors out known imprecision of scores to generate the norms are also provided in detail, along with the snapshots of the achievement and growth norms for each test.

The purpose of this technical appendix is to share more detailed results and describe the sample and methods used in the research in Progress towards pandemic recovery: Continued signs of rebounding achievement at the start of the 2022-23 school year.
New research provides evidence that student reading and math achievement at the start of the 2022–23 school year is continuing to rebound from the impacts of the pandemic, though full recovery is likely still several years away.
The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, The widening achievement divide during COVID-19.
New research provides additional evidence of the uneven impacts of the COVID-19 pandemic showing that students’ math and reading test scores are more variable in spring 2022 than before the pandemic in part because the divide between high and low achievers has widened.
New NWEA research provides further evidence of the challenges that young learners are currently facing from the disruptions of the COVID-19 pandemic.
New research using longitudinal data provides evidence that deaf and hard of hearing (DHH) students continue to build skills in math and reading throughout grades 2 to 8, challenging assumptions that DHH students’ skills plataeu in elementary grades.
