The Mendez Foundation developed Logic Models for Too Good to map out the Theory of Change and demonstrate graphically the assumptions that drive the learning and behavior change in Too Good. The logic model communicates an "if-then" message of what changes the program intends to produce. It helps to make the connections among the target group, goals, strategies, objectives and planned program results and lays out what the program is expected to achieve and how it is expected to work.
Each of the Too Good evaluation studies were conducted by third-party researchers and used randomized treatment-control group designs (pre-test/post-test, 20-week post-test, or one-year follow-up). The Researchers examined pre-test equivalence between treatment and control groups; potential bias of loss of student data over time; quality of program implementation; and estimates of reliability and validity of assessment tools.
The award-winning Too Good programs have undergone rigorous, independent evaluation studies to measure their effects on students' skills, attitudes, intentions, and behaviors. Studies have been published in peer-reviewed journals and presented at national evaluation conferences. These studies demonstrate the effectiveness of Too Good.
