The U.S. Department of Education (ED) expects all Teacher Incentive Fund (TIF) grantees to conduct an evaluation of their programs. Experience with earlier rounds of TIF grants has shown that evaluations can provide valuable information for managing and improving TIF-supported activities, as well as evidence that these activities have had a positive impact that can help grantees make the case for sustaining the work after the grant has ended. In addition, ED is interested in learning how TIF grants have improved educator effectiveness, student achievement, and equity of access to teachers for students from low-income families and minority students across and within schools and districts. This guidebook provides strategies and resources to address the many complexities and challenges involved in evaluating a TIF program, from conceptualizing the evaluation questions to reporting results. It begins by providing a process for identifying the logic of how the TIF program will lead to the desired outcomes (Section 1), moves into how to develop evaluation questions that examine this logic (Section 2), and then explores methods for measuring these evaluation questions (Section 3) and choosing an appropriate evaluation design for assessing impacts (Section 4). The guidebook also describes best practices for disseminating evaluation findings (Section 5) and processes for choosing the right evaluator (Section 6). The following are appended: (1) Internal and External Validity; and (2) Program Evaluation Standards.
