Teachers and school administrators can measure students' academic achievement through school-wide standardized tests, state-specific achievement tests and classroom assessment. Standardized and state tests enable educational professionals to see how a school's students are achieving in a variety of subjects compared to those at other schools and geographic locations. Classroom assessments enable teachers to see how well students are learning concepts for a specific class.
Educational professionals can use standardized and state-specific test results to find gaps in achievement and make plans to help students improve in the weakest domains or subject areas. Teachers can use low-stakes assessments to examine gaps in learning as they're still teaching particular concepts in class, while they can use high-stakes assessments to measure academic achievement after a learning period, such as a class unit, has been completed.
