Multi-Classroom Leaders (MCLs) reach more students by leading a small team of teachers with intensive support—co-teaching, coaching, modeling, co-planning, and leading student data analysis—while taking accountability for the learning results of all of the team’s students; this also provides districts with an internal leadership development pipeline.

Direct-reach teacher roles vary by school. Some of these teachers work on a team led by an MCL, and some teach independently. Beginning in 2018–19, all direct-reach teachers in new OC schools will work on MCL-led teams alongside team teachers.

Expanded-Impact Teachers reach more students by swapping some teaching time with paraprofessional-supervised projects and skills practice.

Elementary Specialists reach more students by specializing in their best subjects (in elementary schools) or roles on a team.

Blended-Learning Teachers (BLTs) rotate students between face-to-face learning and digital instruction, projects, and skills practice, typically on a schedule, allowing them to teach more students.

Team Teachers work on a team led by an MCL, receiving intensive support from the MCL and working collaboratively as a team to review student progress and adjust instruction to ensure high-progress learning for every student. Each team teacher is accountable to the MCL for their contributions to the learning outcomes of each student, with specific goals and measures dependent on the role each plays.
