Arizona's Board of Education has approved state superintendent Tom Horne's recommendations for school safety.
With more than $100 million in funding, Horne's department plans to increase the total number of Arizona schools that have resource officers on campus, raising the number from 190 to 301.
An additional $45 million will cover salaries for 566 new counselors and social workers.
The funding comes from a combination of federal and state grants.
The state funding requires armed officers to be given top priority.
