Secondary Intervention Teacher - 9th-12th Grade - 2025/2026

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, all means all. Nearly one quarter of Mastery students have individualized education plans (IEPs) to ensure they receive appropriate, just-right, educational opportunities. At Mastery, we believe the IEP creates an opportunity for teachers, parents, school administrators, case managers, related services personnel, central office staff and students (when appropriate) to work together to improve educational results for children with disabilities. We believe we can push the boundaries of what’s possible for our students. To accomplish this, special education teachers at Mastery deliver robust research-based interventions, frequently monitor progress and make logical adjustments to produce the best possible outcomes for students.

Across Mastery our Specialized Services Programming spans from itinerant to supplemental levels of support. Our highest priority is for our diverse learners to spend as much time as possible within the general education setting and the minimum amount of time in self-contained classrooms. We strive to maximize our teacher-to-student ratio in our Special Education programs. To accomplish this, we have multiple classrooms across our network tailored towards Autism Support, Emotional Support, Life Skills and Multiple Disability Support as well as Multi-Lingual Learner Support.

At Mastery, we have a robust Response to Intervention program and are excited for you to bring your enthusiasm, skills and experiences to the team. We have a wide variety of Common Foundation research-based curriculums to support our diverse learners across grades K-12 in Reading, Math and Writing. Our Reading intervention programs include Fundations, Just Words, Wilson, Heggerty, Waggle, System44, Read180, i-Ready and IXL. Our Common Foundation research-based Math intervention programs include TouchMath, Number Worlds, Math180, i-Ready and IXL. Our Common Foundation research-based Writing intervention programs include Quill, Adventures in Language and Writing for Success.

At Mastery, we highly value Continuous Improvement and want to ensure you accelerate your professional growth as a special educator, so we have frequent embedded opportunities for Professional Development, teacher coaching, skill building and data driven-instruction meetings throughout the school year.

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.
