Our Schools

Admission to Monocacy Valley Montessori Public Charter School (MVMPCS) and Carroll Creek Montessori Public Charter School (CCMPCS) is determined from the results of two separate lotteries.

What is a Charter School?

Maryland charter schools are independent public schools with the freedom to innovate while being held accountable for improved student achievement. We foster partnership between parents, teachers and students to create an environment in which parents can be more involved, teachers are empowered and students excel.
