Schools and districts across the country are being subjected to some of the fiercest budget cuts in recent history, even as principals are held increasingly accountable for significantly improving student achievement, particularly in schools labeled "persistently low-achieving." For the 5,000 lowest-performing schools, there is the option of (and tremendous pressure to win) Title I School Improvement Grants (SIGs), which can provide millions of dollars over the course of three years to help them turn around. But not every needy school will develop a successful application, and even for those schools that do succeed, the money alone will not change their learning environments. There are three resources that are likely under school leaders' control: personnel, programming, and time. Using data to reallocate teachers, adjust programming, and reconfigure time can create dramatic results at little expense.
