The Arizona Charter Schools Association is asking its members to share their safety policies so other charters can look for practices to adopt.
Association spokeswoman Megan Gilberton says about 45 of Arizona's 535 charter schools have submitted policies so far.
Arizona district schools are required to complete emergency response plans. Department of Education spokeswoman Molly Edwards says charter schools are not required to do that, but many do anyway.
Tempe Police Chief Tom Ryff says charter and private schools haven't received the same attention as district public schools regarding safety threats such as shooters.
Ryff recently convened a meeting of educators and emergency responders to discuss preparedness.
The Arizona Republic reports that Ryff planned the meeting before the Connecticut school shooting.
