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.
