1) Ask about the teachers: How qualified are they? Where did they receive their degree? What's their teaching style? Any school should be able to provide you with this information.
2) Learn the school's structural program: "It's important to know your child's education will be supplemented from year to year," says Lubienski. In other words, will the English class she takes in fourth grade build on the knowledge she learned the previous year, or will it be a randomly selected class?
3) Know the school's philosophy: It may seem trivial, but knowing things like how active the school's PTA is and the faculty's style of discipline, will give you confidence that your child's best interests will be taken to heart.
