In Winter 2021-2022, the Nebraska Student-Centered Assessment System (NSCAS) assessments are administered in ELA and mathematics in Grades 3-8. In Spring 2021-2022, the NSCAS assessments are administered in English language arts (ELA) and mathematics in Grades 3-8 and in science in Grades 5 and 8. The purposes of the NSCAS assessments are to measure and report Nebraska students' depth of achievement regarding the Nebraska College and Career Ready Standards; to report if student achievement is sufficient academic proficiency to be on track for achieving college readiness; to measure students' annual progress toward college and career readiness; to inform teachers how student thinking differs along different areas of the scale as represented by the range achievement level descriptors (RALDs) as information to support instructional planning; and to assess students' construct-relevant achievement in ELA, mathematics, and science for all students and subgroups of students. This technical report documents the processes and procedures implemented to support the 2021-2022 Nebraska Student-Centered Assessment System (NSCAS) Growth in English language arts (ELA), mathematics, and science assessments by NWEA® under the supervision of the Nebraska Department of Education (NDE). The technical report shows how the processes, methods applied, and results relate to the issues of validity and reliability and to the Standards for Educational and Psychological Testing (American Educational Research Association, American Psychological Association, & National Council on Measurement in Education, 2014).
