School districts across the nation will be able to apply for competitive grants to develop or update their school safety plans, U.S. Sen. Barbara Mikulski announced Wednesday in Baltimore County.

The new Comprehensive School Safety Initiative will provide $50 million to school districts across the country who want to train and hire school personnel and buy equipment to improve school safety.

Another $25 million will be used for research into analyzing the causes of school violence, including the gaps in mental health for students and their exposure to violence.
