Testing helps schools identify weaknesses.
Testing students creates data that can be analyzed to identify weaknesses in both students and teachers, providing both with information needed for specific improvements. Test data can illuminate good practices. When test scores are combined with demographic data, it becomes possible for educators to identify those schools and instructional programs that are succeeding despite poverty and other obstacles. Those high-performing schools become models for reform. In troubled schools, involve the parents.
