The goal would be to create a system where all IPS schools would be good enough to be Opportunity Schools within six to eight years. We believe it is likely that a handful of schools would be strong enough to qualify as Opportunity Schools immediately. We estimate that each year up to 10 new schools could be incubated to replace poor-performing schools. And a few existing schools with strong potential may improve enough each year to become Opportunity Schools. But the overall timeline would depend on how successfully IPS incubates great new schools, turns around struggling schools, and recruits highly effective school leaders and teachers.
