This study used growth curve modeling to investigate trends
in reading and math proficiency in each state over a four- to six-year
period for grades 3–8. It found that:
-
The school-level percentage of
students who scored proficient in reading and math increased in Florida,
Mississippi, and North Carolina; the percentage also increased for most
racial/ethnic and economic subgroups.
-
Achievement gaps decreased for most
racial/ethnic and economic subgroups across grades, subjects, and states.
-
Proficiency achievement gaps
remained large across grades, subjects, and states despite significant
decreases.
