The attorney general and the Ohio Department of Education are partnering on the free training for teachers and administrators. Police officers also were invited.
More than 200 people registered for the first sessions, scheduled Thursday in Columbus where Attorney General Mike DeWine will be on hand.
The state says planning for the training began after the school shooting in Chardon that left three students dead last February. It says the December massacre at a Connecticut elementary school created a surge in interest and accelerated scheduling of the sessions.
