Why is measuring both achievement and progress important?
Achievement measures provide educators with a snapshot of student’s growth at a single point in time and how well those students perform against a standard. Progress measures provide a more complete, accurate picture of student growth from year-to-year, including how much growth or gain a student or groups of students make over time. By combining achievement and progress information with other data sources, schools and districts will have a more robust, comprehensive picture of their impact on student learning.
