Harrity Elementary | Mastery Charter School

Your Neighborhood School in Southwest Philadelphia

Welcome to Harrity! From math to music, and reading to field trips, our students receive a well-rounded education from loving teachers and leaders.

In February 2020, the School District of Philadelphia awarded us for having two tiers of growth on the school progress report, which considers standardized test scores, academic growth and other measures.

We provide all students with free breakfast and lunch and also offer an aftercare program.

At Harrity, we believe all of our students have greatness within. With love and high expectations, we support them in finding their own paths to success.

Stop by and visit us any time!







Our School

  • Students come to school excited to start their day, with their laptop in hand.

  • Students head back to the cafeteria to enjoy free lunch.
  • Afterward, students enjoy free play or structured recess.
