This report describes the Achieve 180 Program in Year 3, the last of the three years initially planned for this comprehensive program. The 54 participating schools received Texas Education Agency campus accountability ratings of "Improvement Required" (IR), "Not Rated," or "Former Improvement Required". The 2019-2020 Achieve 180 Program's centralized support was based on six pillars of best practice for school improvement and is delineated in this report. Achieve 180 Implementation Rubric Dashboard ratings included in this report were calculated by the Achieve 180 Program administrators in consultation with other district and school administrators to depict the level of implementation fidelity achieved for each Achieve 180 Program centralized support provided at each participating school in 2019-2020. Also included in this report are 2019-2020 Achieve 180 Program Survey responses and full versions of the Cross-functional teams' and department leaders' Achieve 180 Program Fall 2019 and Spring 2020 reports which enumerate the program's massive implementation strategies and activities, accomplishments, insights, and recommendations for program improvement. Key impacts of the COVID-19 pandemic on program implementation activities are cited in the reports.
