To make decisions, the school staff uses facts from test scores, student records, research studies, state and district standards, and other sources. They continue to collect new facts to see if their decisions helped students. Instead of just using one or two big tests each year to mark themselves, they also use many frequent, smaller ways to see if what they are doing helps students. If new facts tell them to change what they are doing, they change. The school’s progress is an open book to parents and community.
