Some practitioners wonder why all the right program components can be in place and yet still not meet program goals. A program evaluation is a critical tool for assessing whether a program is working or not and why. This is the third in a series of six practitioner training modules developed as part of the Career & Technical Education (CTE) Research Network Lead. Designed for CTE practitioners and state agency staff, these modules are designed to strengthen the capacity to access, understand, and use CTE data and research as well as conduct one's own research, particularly causal research. This module teaches about when and why to conduct a program evaluation, the different types of evaluations, the role of logic models, best practices in program evaluation, and the difference between a program evaluation and performance measurement. This module is designed to support school district and college CTE program administrators in understanding program evaluation.
