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.

This role is eligible for signing and relocation bonuses.

New teachers start at $60,000, with Mastery offering up to $82,000 based on experience and education. Salaries range from $60,000 to $106,500, with growth opportunities as your career progresses.

The Opportunity:

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.

As a Math Teacher 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. You will receive more than 250 hours of professional development annually and have a professional development allowance to use to further your growth.

Duties and Responsibilities:

• Drive student achievement and set high expectations for all students.
• Commit to professional growth, self-reflection, a receptiveness to feedback, and a desire to continuously improve.
• Implement rigorous and appropriate lesson plans, assignments, and assessments in cooperation with Mastery school-based leadership and curricular resources developed by Mastery’s central office Academic Team.
• Work closely with school leaders to analyze student assessment data to measure progress and use data to inform instruction.
• Collaborate in grade-level teams to discuss student work, share best practices, plan events for joy and humor, and ensure student mastery of standards.
• 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.

Education, Experience, and Skills:

• Bachelor’s degree required with a record of personal, professional, and/or academic achievement.
• Teacher certification - completed or in process.
• Demonstrated expertise in subject area.
• Outstanding instructional skills driven by data and delivered through rigorous and engaging strategies.

Physical Requirements:

• Ability to physically perform the essential duties of the role, including traveling to network campuses and maneuvering in office spaces (standing, walking, sitting for long periods, speaking loudly and clearly, seeing and hearing things both near and far away).
• Fine finger and hand manipulation in use of computer, chalkboard, dry erase, and/or projectors; filing, faxing, scanning, copying, typing, mailing, and making phone calls.

Mastery's Benefits Package:

We offer a full benefits program and opportunities for professional growth. Some of our most popular benefits include our 403(b) retirement plan for PA employees (with a 5% match from Mastery), enrollment in the State of New Jersey Pension Plan for NJ employees, a robust Employee Assistance Program, mental health and counseling programs, an annual Professional Development Fund, and discounts and perks at a myriad of retailers, travel organizations, insurance providers, and more.

Annual Calendar:

Please feel free to review our Calendar for the 24/25 School Year.

Why You Should Apply:

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.
