Your Neighborhood School in North Philadelphia

Welcome to Mastery Charter Frederick Douglass Elementary, recognized by the School District of Philadelphia for 5 consecutive years of academic growth! (SPR 2018-19)

When you walk through our doors, you can feel the students’ joy and excitement to learn, as well as the love our teachers and school leaders have for every child in the building. We pride ourselves on challenging our students academically and educating the whole child. That means along with the core classes of math, science and reading, we focus on the core values of respect, responsibility, hard work, teamwork and kindness.

Students who attend Douglass Elementary have the opportunity to attend our Simon Gratz High School, giving them a full K-12 Mastery experience.









Our School

  • Students come to school  excited to start their day with their laptop in hand.  
  • Free breakfast!
  • After breakfast, teachers welcome students to class and begin the morning meeting. 
  • Reading is very important, especially for students in grades K-2 when they are just learning how to read. That’s why our younger students have at least 2-3 hours of reading lessons each day.
  • In addition to reading, students have math, social students and science classes. 
  • Time for lunch!
  • After lunch, students in the lower grades have free play or a structured recess. 
  • In addition to our core classes, students also take physical education, music or a foreign language.
  • Once the school day is over, it’s time for after-school clubs and our optional aftercare program.
