The Research and Evaluation Bureau developed the The Layered Evaluation Strategy (LES) to carry out evaluations. LES is a program evaluation methodology that applies global research questions within three interdependent and primary program layers to address specific programmatic elements in a comprehensive, yet flexible manner. The three layers are 1) participant background factors, 2) program factors, and 3) program outcomes. The global research questions and three layers within any LES evaluation remain constant, bu t the subquestions are specifically adopted to each program evaluation or initiative. Using both quantitative and qualitative data, the goal of the LES evaluation is to identify facilitators, barriers, and best practices relevant to any program design and implementation. The related LES layers and corresponding research questions follow:
1. Participant background factors
a. What are the background characteristics of the participants? These characteristics include, but are not limited to, gender, race, age, socioeconomic factors, and primary geographic residence.
2. Program factors
a. What is the substance of each program initiative?
b. How do stakeholders interact within each program initiative?
c. How satisfied are participants with each program initiative?
d. What evidenced-based best practices can be identified within each program initiative?
3. Program outcomes
a. What are the specific initiative outcomes as defined by each program initiative?
