(AJC) — Georgia is only one quarter of the way into its four-year, $400 million federal Race to the Top grant, but school districts are already seeing changes. Atlanta is starting a program to recruit teachers to high-need urban schools. Bibb County is hiring graduation coaches for high schools and buying hand-held computers for students at low-performing schools. Gwinnett County — the state’s largest district with 150,000 students — is helping other school systems mimic the district’s successful grow-your-own-principal program. At least two more districts — DeKalb and Gwinnett — are getting coveted Teach for America slots, bringing in recent college graduates to low-income schools to teach for two years. The state also hopes to open slots in Clayton County.
