Our dedicated and highly qualified teachers and staff ensure that all students receive a well-rounded education in a fun and joyful environment.

Thomas Elementary is a top academic performer among Philadelphia schools, with PSSA proficiency results more than doubling the School District of Philadelphia’s average. To support student success, we offer a variety of free tutoring services for families, and provide robust English language programs for multilingual students. To support our families, we also offer weekly English language classes specifically designed for non-English speaking parents. 

Every Mastery school has a dedicated school culture team that is responsible for ensuring a positive and safe school community. Our schools observe common rituals, such as morning meetings, community gatherings, and events that celebrate the school community and the joy of learning. We also ensure that school rules and values are consistently supported and enforced. Our teachers adopt standard school-wide classroom behavior systems, ensuring that students are held to consistently high expectations. We intentionally create a community that strikes a balance between structure and student independence, allowing schools to feel both orderly and joyful.
