In this technical report, we present the results of a 2020-2021 study of the alignment between the easyCBM© mathematics and literacy assessments and the content standards adopted in the fifty U.S. states. The study used a three-wave process. First, a team of researchers gathered the status of state standard information for mathematics and English language arts (ELA) standards across grades K-8 for all 50 U.S. states. Three main groups were identified: CCSS Adopted (20 -- ELA & Math), CCSS Revised (24 -- ELA, 28 -- Math) and State Unique (6 -- ELA, 2 Math). Next, the team analyzed the alignment between the standards and the easyCBM© literacy measures. Finally, the team analyzed the alignment between the standards and the easyCBM© mathematics measures. This technical report describes the process used in the alignment study and provides the results of the analysis.
