The Greece Professional Learning Center, a New York State Teacher Center in Greece Central School District, works to ensure all district employees have access to high-quality professional learning that supports and facilitates their learning and ultimately advances student achievement. The center is an integral part of the district -- the state's 9th-largest -- and the community. An important part of the center's work is evaluation. As Learning Forward states in "Standards for Professional Learning" (2011), "Well-designed evaluation of professional learning provides information needed to increase its quality and effectiveness" (p. 38). New York State includes evaluation in its Professional Development Standards: "Professional development is evaluated using multiple sources of information to assess its effectiveness in improving professional practice and student learning" (New York State Education Department, n.d.). Here a group of educators and community members gain an understanding of how best to gather feedback to make informed decisions about future professional learning and how feedback data serve different audiences.
