With the increased inclusion of student academic growth in school accountability decisions, the Center on Standards and Assessment Implementation (CSAI) has received multiple queries regarding how states are incorporating student growth measures into their accountability systems. CSAI recently sought to answer this question through a scan of state systems, reviewing states' Elementary and Secondary Education Act (ESEA) flexibility waivers to find out what states use student growth measures and which measures they use. This CSAI Update provides the results of that scan, results that might provide some insight for states looking to add this kind of measure or to rethink the growth measure they are currently using.
