Big news for Challenge to Excellence! We’re proud to share that C2E has earned the Governor’s Distinguished Improvement Award from the Colorado Department of Education for the first time ever—a major recognition of the growth and progress happening across our school.
We also received the John Irwin Award from the Colorado Department of Education, which is given to schools that demonstrate outstanding academic achievement in reading, math, and science. Based on our strong CMAS results, C2E is proud to be the only charter school in the district to earn both awards.
