Interim/benchmark assessments provide school and district administrators with student data that can reveal trends and patterns in student performance. They are more comprehensive in scope than formative assessments—think of a test given at the end of grading period, rather than quizzes and chapter tests given throughout the term.
Interim/benchmark assessments help to identify learning gaps and additional resources to support specific content areas, grade levels, or student groups. They can serve a predictive role, projecting how a student or a class will do on an end-of-year summative assessment. Teachers can adjust their lesson plans according to the needs that these interim assessments identify.
