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 Multilingual Programs at Mastery Schools are built on the belief that native language skills are a true asset and transfer to secondary language learning. Based on this, students receiving ELD services are taught social & instructional language in tandem with academic language of Language Arts, Math, Science, and Social Studies throughout each stage of English proficiency.  ESL teachers work with our multilingual learners to build students’ language capacity, gain greater levels of access to the curriculum and bridge students’ prior learning and experiences into English-instructed classrooms and school environment.

 

Mastery values the language and cultural diversity that English Learners bring into our schools. We strive to incorporate the literature and historical perspective of our multilingual learners into the curriculum, school community, and classroom culture.
