No one knows a school's weaknesses and needs like its principal, who is often called upon to come up with ideas for programs, products, and services to address them. The problem is that most ideas, whether they involve personnel, equipment, software, or materials, require money. Because most schools operate with limited resources and fixed budgets, it is difficult to allocate funds to support many potentially promising ideas. But it doesn't have to be this way if principals are willing to look for grants to fund their ideas.
