 | |  SSA is based on the following principles: - SSA supports schools in developing a culture of inquiry and reflection focused on the continuous improvement of teaching and learning.
- SSA occurs within the context of a schools teaching and learning goals, not according to an external checklist.
- SSA fosters an evidence-based approach that identifies and describes the ways in which a school is meeting its goals and encourages schools to build on the areas in which they are already strong.
- SSA raises questions to help schools improve teaching and learning; it does not give schools a recipe for reform.
- SSA depends on the commitment and knowledge of educators trained in the methodology of review to make informed judgments about schools.
| |  In Michigan, 15 schools, including rural and urban schools in predominantly low-income districts, have become engaged in SSA from 1997 to 2002. AED provides a program of professional development that is research-based and aligned with national standards for professional development. The professional development consists of a sequence of workshops and institutes; an ongoing network for SSA practitioners; and on-site assistance from regional partners. | |  | | |
