Page | 4 • Level 4: Demonstrates a Rationale. A well-specified logic model, informed by research suggesting how the intervention is likely to improve relevant outcomes. A Level 1, 2, or 3 study of the intervention is planned or is underway elsewhere. This document presents the ESSA Level 4 evidence study conducted by SEG Measurement (SEG) on behalf of Vista Higher Learning (VHL) for VHL’s Bridges program. Evidence supporting the use of Bridges for grades 6–8 is provided. Level 4 evidence is central to building an argument for the e7ectiveness of Bridges. It defines the claims made for Bridges and provides supporting evidence from the Bridges instructional strategies, materials, and activities, as well as the WIDA standards and current research supporting claims of the e7ectiveness of Bridges . The SEED E3ectiveness Evidence Framework for Bridges The Level 4 evidence framework is an ideal starting place for building an evidence base. There is no single correct way to create a Level 4 evidence framework. At minimum, it should describe the product, delineate the underlying logic or rationale, and identify the intended outcomes and claims. The framework should also present the linkage between the outcomes and the product instructional components producing those outcomes, as well as the linkage between the product instructional components, accepted standards, and existing research. Other pieces of evidence bearing on the validity of the claims may be case studies, prior studies, and other documentation supporting product e7ectiveness. The e7ectiveness evidence framework completed for the Bridges Level 4 E7ectiveness Study is provided below.
