About Acera


We envision a world in which schools engage students in meaningful learning, in which teachers are freed as entrepreneurs in their classrooms, and in which students can become the best version of themselves, given each students’ unique capacities, needs, and passions. The Acera School day program provides students with unbounded access to learning, offering high-capacity students opportunity according to their ability, not age. Acera’s enrichment programs (after school, summer, and vacation week camps) are open to the public, and our Education Innovation (EI) efforts are actively engaged in public school projects to support educational change. We also partner with organizations beyond our walls, creating programs rich in sciences, technology, engineering, creativity, and the arts. We operate both as a lab school and a microcosm of what is possible for other schools. We seek to grow students’ emotional intelligence and develop the next generation of innovators, leaders, and creative thinkers who can make a positive impact in the world.

Job Duties & Responsibilities


A core part of Acera’s program is our ability and readiness-based math block model. We initiate each school year with a snapshot assessment experience for every student, ensuring that students are placed in classes based upon their ability without limits due to curricula or age. 


We seek to hire math educators to lead at least one multi-age class of gifted upper school students. We are looking for someone who can challenge students and get them to approach math with joy, logic, and grit. These are students who are learning above grade level, which means there is freedom to include enrichment topics and topics outside of the standard curriculum. You should provide opportunities to creatively tackle new problems, explore patterns, and develop numeracy.


We do not assign grades at Acera; instead, we give frequent formative feedback in class, write student comments for progress reports, and communicate regularly with families. Progress reports give students and their families insights into mastery level as well as learning styles.


For full-time, school-year candidates: teach one section of math, one to two elective courses, be an individual passion projects mentor, and other duties as part of the school community.


For part-time, school-year candidates: teach one section of math, with the opportunity to lead additional courses.
