Your Neighborhood School in Germantown

Welcome to Mastery Charter School Pickett Campus!

We’re a neighborhood school in the Germantown community in Philadelphia, serving nearly 900 students in grades 6-12.

Students enjoy a strong sense of community and belonging in a safe environment, supported by caring and committed teachers and staff who return year after year. Along with a rigorous academic program, our students have opportunities for internships, and tons of sports and extracurricular activities including football and dance team.

When they become upperclassmen, they can take AP classes and participate in a dual enrollment program to earn college credits while they are still in high school.

At Pickett, we believe all of our students have greatness within. With love and high expectations, we help them find their own paths to success.

Stop by and visit us any time!







Mastery Pickett employees had a blast participating in a virtual team building event with VIP Teambuilding (teambuilding.com).  Staff played virtual games like Office Trivia  and “Can you hear me know?” to build community for the new school year!

"There's a charter school called Mastery in Philadelphia. And in just two years, three of the schools that Mastery has taken over have seen reading and math levels nearly double - in some cases, triple...One school called Pickett went from just 14% of students being proficient in math to almost 70%. Now - and here's the kicker - at the same time academic performance improved, violence dropped by 80% - 80%. And that's no coincidence...Now, if a school like Mastery can do it, every troubled school can do it."

-President Barack Obama
