Evaluation of the EPO Program


The IRIS EPO portfolio is evaluated through a strategic combination of internal and external evaluation practices, applied throughout the lifecycle of a project, with the goal of maximizing the desired programmatic impact. This approach is approach, based on the Collaborative Impact Analysis Method (IAM) (Davis and Scalice, 2015), which combines staff knowledge of programs and products, audiences, and content, with the expertise of an outside evaluator. This combination captures the effects on the behaviors, attitudes, skills, interests, and/ or knowledge of users/program participants, while achieving efficiencies by having IRIS staff conduct much of the development of assessment instruments, data collection efforts, and preliminary data analysis.  To ensure success, an external evaluator provides consultation, review and feedback, and/or more robust analysis of data. Risks are monitored on a project-by-project basis as part of the evaluation process, allowing resources to be reallocated as needed to keep projects on schedule.

Each project in the portfolio is annually reviewed jointly with the external evaluator. Working with the staff lead for the project, the external evaluator scores the robustness of the project’s current evaluation, using a qualitative rubric based on best practices. The outcome of these annual reviews is a project score and steps to improve the project’s evaluation and impact. In this way, the process delivers the formative and impact data to ensure project efficacy and efficiency. Periodically, each project prepares a report on the impact of the evaluation on the project going forward. These reports are used for high-level, cross-program analysis and strategic planning. In addition, the program activities are monitored regularly by the EPO Standing Committee and at longer intervals by a separate external panel and independent evaluator.
