Positive School Environment

To foster a positive school environment where all students are educated in a safe and caring atmosphere, all Archdiocesan schools will follow established procedures for prevention and intervention for bullying, harassment or intimidation.

Positive Behavioral Intervention & Supports (PBIS) has been implemented in every Archdiocesan elementary and high school to enhance academic and social behavior outcomes for all students.



In accordance with standards set by the Archdiocese of Baltimore, Mother Mary Lange Catholic School will meet the requirements established by the Cognia Accreditation Commission and Board of Trustees, and thereby be accredited by the NCA Commission on Accreditation and School Improvement, the Northwest Accreditation Commission, and the SACS Commission on Accreditation and School Improvement.  

Governance Model

Mother Mary Lange Catholic School is an Archdiocesan Collaborative School (ACS), which is a model of shared governance developed by the Archdiocese of Baltimore. The ACS model utilizes a shared governance model that fosters unity through the collaboration of stakeholders in support of Catholic schools. The model allows decisions regarding day-to-day school operations to be made at the local level, while individual schools and school administrators are supported centrally from the Department of Catholic Schools and the Catholic Center's Central Services in areas such as academics, finance, development, enrollment management, and marketing.
