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

Stephanie Keenoy is the founding principal of Achievement First Endeavor Elementary School. Ms. Keenoy joined Achievement First in 2010 as a principal-in-residence at Achievement First Brownsville Elementary where she coached several teachers, served as the first-grade chairperson and developed a Friday professional development calendar for teachers. She graduated from the College of William and Mary in Virginia with a dual degree in psychology and elementary education. After college, she served as a Teach For America corps member in Atlanta, Georgia, and was recognized with the prestigious Michael’s Family Award for Excellence in Education. Ms. Keenoy received her M.Ed. in reading and literacy from Boston College through the Donovan Urban Scholars Program. While in Boston, she taught in a third-through-fifth-grade severe special education classroom as well as a full-inclusion second grade classroom.
