An effort to reform teacher professional development is on a parallel course with the statewide academic standards and assessment system stipulated by the State of Washington's School Improvement Act (House Bill 1209). Five college/university and school district partnerships have been commissioned to develop and field test a new performance-based teacher certification program. One of the partnerships, the Shoreline School District/Seattle University Model, includes preservice coursework, an internship and a residency program integrating the support of experienced teachers, principals, district educators, university faculty and other professional educators. The teacher performance standards of effective teaching, professional development and leadership adopted by the Washington state legislature include 22 comprehensive knowledge and skills requirements. For this program, they have been translated into a standards matrix to guide the growth and assessment of new teachers. Teacher performances are identified in relation to each of the 22 requirements followed by criteria reflecting the developmental levels of building knowledge, exploring and making a plan, implementing a plan, and refining performance.
