Libertas Academy Mission:
Through rigorous academics, character development, and strong supports for every learner, Libertas Academy Charter School prepares all sixth through twelfth grade students to succeed within the college of their choice and to be positive, engaged members of their communities.

Organizational Overview:
Libertas Academy Charter School is a high expectations, high achieving school that replicates the successful models of other high performing charter schools in Massachusetts and across the country. Within an achievement-oriented culture in which expectations are clear and routines are consistent, and in which the joy of learning, the power of intellectual curiosity, and the development of life-building values are at the center of our seamless 6-12 school, all learners build the skills, knowledge, and character required for college and professional success and a life of positive community engagement.

Imagine teaching at a school where everyone in the building is on the same page, holding students to a relentlessly high bar of academic and behavioral expectations. We are looking for teachers who know that holding high expectations and relentlessly pushing students to reach them is a profound form of love. We are looking for teachers who aren’t afraid to do whatever it takes—teachers who know the finish line is college graduation and are in it for the long haul.
