The CDC’s Division of Adolescent and School Health (DASH) has a slide presentation on injury and violence in schools, available for use by the public. It addresses intentional and unintentional injury; suicide/violent deaths; and prevention and response strategies. The stats are a bit old, so it would probably be beneficial to update them if you were to use them for more than just self-education. You might also want to run spell-check on the slides before using them in any formal way (because someone at CDC didn’t).
Fortunately, CDC is very clear about their terms of use policy and what you need to do in order to alter these slides:
Terms of Use:
This CDC slide set is in the public domain. You may reproduce these slides without permission as long as they are not changed in any way. However, if you wish to adapt and/or revise these slides, you must remove the CDC name, logo, and any other references prior to use. Failure to follow these procedures could result in legal action.
