The Colorado Department of Education has identified classroom teaching and school leadership as the strongest school-based factors impacting student achievement. CDE is helping the state’s 178 school districts attract, prepare and support great educators. Each school district must publish to its public written educator evaluation systems that align with Colorado's Educator Effectiveness Bill (Senate Bill 10-191). For more information, visit the Educator Effectiveness page on the CDE website. On this page, we'll provide the documents School District 49 uses for evaluation procedures in each of its zones.
