2023 Wisconsin Act 199
[2023 Senate Bill 303]
Defining Critical Mapping Data
for School Safety Plans
BACKGROUND
State law requires each public school board and the governing body of each private school, to have a
school safety plan in effect, and to review and approve that plan at least once every three years after it
goes into effect. Upon creating the plan, and upon each subsequent review, the board or governing body
must submit a copy of the most recent blueprints or interactive critical mapping data of the school to
the local law enforcement agency with jurisdiction over the school and to the Office of School Safety
(OSS) at the Wisconsin Department of Justice (DOJ). The OSS must coordinate with schools to compile
and keep confidential all blueprints and critical incident mapping data, unless a law enforcement
agency requests access.
Also under state law, DOJ administers a grant program to assist school boards and governing bodies of
private schools in submitting critical incident mapping data. Grant funds must be used for site-specific
critical incident mapping data to enhance security and increase situational awareness for first
responders, and any mapping data created with grant funds must meet certain requirements.
2023 WISCONSIN ACT 199
2023 Wisconsin Act 199 changes the term “critical incident mapping data” to “interactive mapping
data” throughout the relevant statutes. The act defines this term to mean “interactive representations of
a specific location that are verifiable, digital, shareable, and shown in real time.”
Effective date: March 24, 2024
