New American Schools (NAS) was formed in 1991 to create and develop whole-school designs that would be adopted by schools throughout the country in order to improve student performance. It was established as a nonprofit and funded largely by private sector donations. NAS founders thought that in the past many reforms were "programmatic," focused on a particular set of individuals in a school or a particular subject or grade level. They believed that adoption of multiple and unconnected approaches to address each area of schooling resulted in a fragmented education program, a balkanized school organization, and low performance by students. NAS's core premise was that all high-quality schools possess, de facto, a unifying design that allows all staff to function to the best of their abilities and that integrates research-based practices into a coherent and mutually reinforcing set of effective approaches to teaching and learning for the entire school. The best way to ensure that lower-performing schools adopted successful designs was to fund design teams to develop "break the mold" school designs that could be readily adopted by communities around the nation. After developing the design, teams would go on to implement their designs in schools throughout the country. This adoption would lead to NAS's primary goal of improving the performance of students. This whole-school approach to educational improvement was a dramatically different way of initiating and disseminating large-scale educational improvements. It was a unique combination of (1) private sector involvement using a venture capitalist approach; (2) the choice of whole-schools designs as a vehicle for reform; and (3) the ambitious goal of scale-up across the country.
