Renovation can be costly, especially when it entails adding a science lab or rewiring a school for computers. If a predominantly black neighborhood also is low-income, schools in that neighborhood suffer even more. Parents can't afford to donate money for books, computers, supplies and the like the way parents in wealthier communities routinely do. So long as public schools in Florida must rely on private donations to keep up, that inequity will continue to exist. Finally, schools in predominantly black, low-income neighborhoods are likely to have a harder time recruiting experienced teachers.
Poverty is a major factor.
Those schools have fewer resources, for the reasons stated above. Their students also often come to school less prepared to learn than children in more affluent areas, making teaching a more difficult challenge. The state's D and F schools serve the poorest communities throughout the state. Some districts are trying to devise ways to keep the best teachers in the most challenging schools. The Orange County school district, where many of the region's predominantly black schools are concentrated, has been working with the local teachers union to create salary incentives to attract and keep good teachers at those schools.
