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:

We live in a world where math unlocks a future of possibilities. As a Math Teacher at Mastery you will work relentlessly to foster a love of math with your students while growing and developing in your craft. From the moment they enter our buildings, young mathematicians at Mastery engage with the cutting edge, open-source Eureka Math Curriculum to develop the skills and understanding necessary to have strong mathematical fluency.

Our Kindergarteners through 8th Graders learn with Eureka so that, from 9th through 12th Grade, they are prepared for the rigors of higher math. From 9th through 12th Grade, Mastery’s students study Algebra I, Geometry and Algebra II, with opportunities for more advanced study in Precalculus, Calculus and Statistics. Our core program for Algebra I/II, Geometry and Precalculus is Agile Mind.

Teaching math at Mastery you will set high expectations and provide high support so that all of your students are able to succeed. You will work alongside our Specialized Services and School Culture teams to ensure your students receive the help they need to thrive.

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.
