Job description

About Mastery

Founded in 2001, Mastery Schools is a public charter network of 23 K-12 schools in Philadelphia and Camden, serving more than 14,000 students.

At Mastery, we’re on a mission to provide all students with the academic and personal skills they need to succeed after graduation and pursue their dreams. Student achievement is not just a goal for our organization; it's the reason we exist, and every member of our team is dedicated to securing student success. We are also committed to pursuing equity, actively disrupting systemic racism, and addressing the disparities that limit our students' choices.

Our culture is built on respect, service, and the belief that the success of our students, their families, and the communities we serve will help us achieve our mission. We foster a positive, open, and inclusive environment where honesty, humor, and continuous improvement are celebrated.

Join us in creating a model urban school district that serves all students with excellence. Together, we can make a lasting impact.

The Opportunity

Kindergarten through 2nd grade classrooms are self-contained, while in most of our schools, teachers in grades 3–6 specialize by subject. Across every elementary classroom, Mastery teachers are committed to closing the literacy gap by providing students with access to rigorous, culturally relevant texts and grade‑level learning. As a K–2 teacher, you will give students the strongest possible foundation for future success. Through 135 minutes of daily literacy instruction—including whole‑group and small‑group learning—you will bring our high‑quality Foundations and Amplify CKLA curricula to life, building the foundational reading and writing skills students need to thrive. You will also deliver 90 minutes of daily math instruction using Eureka Math² while fostering students' curiosity, social‑emotional development, and knowledge of science and social studies throughout the school day. At Mastery we value Continuous Improvement and want you to learn and grow in your craft. We utilize a team of Assistant Principals, central‑office coaches, and school‑based content teams to provide every teacher coaching and feedback. We have professional development or peer collaboration time built into our staff calendar. You will receive professional development annually and have a professional development allowance to use to further your growth.

• Engage families in their children’s education by building relationships and maintaining regular communication
• Demonstrate genuine interest, belief, and care for students’ personal and academic success
• Respond positively and effectively to challenges with a solutions‑oriented resiliency

Why You Should Apply

Studies have shown that women and people of color are less likely to apply for jobs unless they believe they can perform every job description task. We are most interested in finding the best candidate for the job, and that candidate may come from a less traditional background. Mastery may consider an equivalent combination of knowledge, skills, education, and experience to meet minimum qualifications. If you are interested in applying, we encourage you to think broadly about your background and skill set for the role. We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist Mastery’s Talent Acquisition Team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
