Yes, MCPS claims the Safe to Learn Act is an unfunded mandate and therefore they use wide latitude with how they comply with it or not. At least that's what was publicly discussed most recently in the BOE during budget hearings.

This (2018) law restructures the governance system for overseeing school safety policies and grants, calls for staffing guidelines regarding adequate law enforcement coverage at all schools, and calls for an expanded role of local school systems in coordinating students’ mental health services.

Maryland Safe to Learn Act of 2018, approved by then Governor Hogan.
