The successful Proposer will employ the ODE-accepted Evaluation Plan to analyze and evaluate the EL Outcomes Program, which may involve the revision, development and/or use of tools, systems, and/or structures, to collect and analyze longitudinal data of district and agency progress within and across indicators specified by Agency. The comprehensive evaluation must elevate insights, best practices, and models of effectiveness that can be implemented in other school districts and organizations across the State of Oregon. This Evaluation Plan must be suitable for use in program planning and as the multi-year external evaluation for the years of identification for identified cohort districts, the Education Service District (ESD) efforts, and the structures for technical assistance and support provided by ODE. The comprehensive evaluations completed by the successful Proposer must be suitable for use for multiple purposes, including as reference in Agency reports submitted to the State of Oregon.
