School Overview

Character building is at the heart of the school’s teaching philosophy. Students participate in daily advisories that address peer interaction, conflict resolution and personal growth. Students are pushed out of their comfort zones and into situations that allow them to build confidence. For instance, sixth-graders went camping and explored caves on a recent end-of-year school trip to the Blue Ridge Mountains. Through the school’s Kindness Campaign, students are rewarded for acts of kindness with Mardi Gras beads. Achievement First Endeavor is proud of its teams and clubs, especially the Rhythm and Funk Jazz Band and the boys’ basketball team, which recently won the NYC Charter School Athletic League Championship.

School Leader

Sarah Lewis is principal of Achievement First Endeavor Elementary School. Ms. Lewis joined Achievement First in 2011 as a Learning Specialist, continued as Dean of Students, School Culture, and Academics before becoming principal. An educator of 13 years, she graduated with her Bachelors and Masters from Hampton University with degrees in English and Education. After college, Ms. Lewis taught kindergarten through sixth grade at a private parochial school, taught over-age students with Norfolk Public Schools, and continued with Broward County’s science magnet school, before taking on the mission of education reform with New York City’s high-performing charter schools including Achievement First. Within AF, Ms. Lewis co-created the common picture, coaches teachers and deans, and develops and leads professional development weekly. As a mentor, administrator, member of the National Alliance of Elementary School Principals, Association of Educating Young Children, and contributor on the board of directors for a non-profit outreach program, it is clear that education is Ms. Lewis’ life and mission.
