Note: States are ranked by annual gain. Scores are adjusted within each test year for student characteristics, student family socioeconomic (SES) characteristics, and racial and SES composition of school. Test scores are adjusted across years for changing social class composition of sample by using 1996 student characteristics, family academic resources, and school racial and SES composition to weight all years.
