Local school boards may provide firearm safety education programs for students in the elementary school grades. To assist local school boards electing to provide firearm safety education programs, the Board of Education shall establish curriculum guidelines for a standardized program of firearm safety education for the elementary school grades to promote the protection and safety of children enrolled in the public schools. The curriculum guidelines shall incorporate, among other principles of firearm safety, accident prevention and the rules upon which the Eddie Eagle Gunsafe Program offered by the National Rifle Association is based. Local school boards electing to provide firearm safety education shall offer instruction pursuant to the Board’s curriculum guidelines and shall integrate firearm safety education into appropriate subject areas, if feasible, to ensure that every elementary grade student completes the course of study in firearm safety education.
