Mastery Charter Schools is a growing network of eleven elementary, middle and high schools that prepare underserved youth for success in higher education and the global economy. We believe that educational inequity is the most pressing social problem facing our country—the civil rights issue of our day. Mastery exists to solve the problem. We believe it is imperative that every child receives a quality, college-preparatory education. Mastery is creating a network of exceptionally high performing urban schools that demonstrate that all students—not just those attending selective schools—can succeed.
Our mission is to see that all students learn the academic and personal skills they need to succeed in higher education, to compete in the global economy, and to pursue their dreams. We live by our motto: “Excellence. No Excuses.”
“I enjoy working with students. Mastery is changing the climate of the community I grew up in.”
“I get to work with children directly and watch them grow in every way each day. I feel like I make a difference, especially with the more difficult students. ”
“The people are dedicated to providing opportunities for students. Straight talk is encouraged, and people are open to new ideas. I am also challenged at my job every day (in a good way).”
“What I find most motivating about working here at Mann is the real love for the students. Teachers and staff go above and beyond to support the children and their growth. ”
“They seem to understand that you do have a life outside of school and respect it. ”
