High School 4x4 Block Schedule Implementation

Starting with the 2025-26 school year, all CHCCS high schools will adopt a unified scheduling model known as the 4x4 Block (with Daily Flex).

  • This model allows high school students to take four classes per semester, with longer daily class periods compared to the traditional seven-period schedule.
  • The Daily Flex component ensures the instructional day remains adaptable to support a wide range of programming needs, while the overall length of the school day stays the same.
