Middle School Science Teacher - 6th-8th Grade - 2026/2027 School Year

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. 

At Mastery, we have fully embraced the Next Generation Science Standards framework to create a transformative learning environment. The NGSS and STEELs approach empowers students to become active participants in their own learning, fostering deep understanding, critical thinking, and a lifelong passion for scientific exploration. From the moment they enter our buildings, our young scientists engage with the core ideas and crosscutting concepts of science through engagement in the practices of science and engineering. As a teacher, you will have the opportunity to engage with this cutting-edge approach, impacting students' lives in meaningful ways.

Our K-12 program includes NGSS and STEELs–aligned curricula that allows our students to actively engage in hands-on experiments, data analysis, and problem-solving, mirroring the experiences of real scientists. Students tackle real-world challenges, enhancing their problem-solving skills and developing a deeper appreciation for the relevance and impact of science in their lives.

Teaching science 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. Embracing NGSS and STEELs means continuous professional development and growth. You'll have access to workshops, training sessions, and collaboration opportunities with fellow educators, keeping you updated with the latest pedagogical practices and scientific discoveries. Together, we can inspire a new generation of scientists, innovators, and critical thinkers who are ready to tackle the challenges of the future.

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 so much more, as well as a Benefits VIP Helpdesk to help you navigate various benefits-related topics.

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.
