(1) Student management.–The district school board may adopt programs and policies to ensure the safety and welfare of individuals, the student body, and school personnel, which programs and policies may:

(a) Prohibit the possession of weapons and drugs on campus, student hazing, and other activities that could threaten the operation of the school or the safety and welfare of the student body or school personnel.

c. The student has committed a serious offense which warrants suspension or expulsion from school according to the district school board's code of student conduct. For the purposes of this program, "serious offense" is behavior which:

(III) Includes possession of weapons or drugs.

(2) Code of student conduct.–Adopt a code of student conduct for elementary schools and a code of student conduct for middle and high schools and distribute the appropriate code to all teachers, school personnel, students, and parents, at the beginning of every school year. Each code shall be organized and written in language that is understandable to students and parents and shall be discussed at the beginning of every school year in student classes, school advisory council meetings, and parent and teacher association or organization meetings. Each code shall be based on the rules governing student conduct and discipline adopted by the district school board and shall be made available in the student handbook or similar publication. Each code shall include, but is not limited to:

(g) Notice that the possession of a firearm or weapon as defined in chapter 790 by any student while the student is on school property or in attendance at a school function is grounds for disciplinary action and may also result in criminal prosecution. Simulating a firearm or weapon while playing or wearing clothing or accessories that depict a firearm or weapon or express an opinion regarding a right guaranteed by the Second Amendment to the United States Constitution is not grounds for disciplinary action or referral to the criminal justice or juvenile justice system under this section or s. 1006.13. Simulating a firearm or weapon while playing includes, but is not limited to:

1. Brandishing a partially consumed pastry or other food item to simulate a firearm or weapon.

2. Possessing a toy firearm or weapon that is 2 inches or less in overall length.

3. Possessing a toy firearm or weapon made of plastic snap-together building blocks.

4. Using a finger or hand to simulate a firearm or weapon.

5. Vocalizing an imaginary firearm or weapon.

6. Drawing a picture, or possessing an image, of a firearm or weapon.

7. Using a pencil, pen, or other writing or drawing utensil to simulate a firearm or weapon.

However, a student may be subject to disciplinary action if simulating a firearm or weapon while playing substantially disrupts student learning, causes bodily harm to another person, or places another person in reasonable fear of bodily harm. The severity of consequences imposed upon a student, including referral to the criminal justice or juvenile justice system, must be proportionate to the severity of the infraction and consistent with district school board policies for similar infractions. If a student is disciplined for such conduct, the school principal or his or her designee must call the student's parent. Disciplinary action resulting from a student's clothing or accessories shall be determined pursuant to paragraph (d) unless the wearing of the clothing or accessory causes a substantial disruption to student learning, in which case the infraction may be addressed in a manner that is consistent with district school board policies for similar infractions. This paragraph does not prohibit a public school from adopting a school uniform policy.

(a) Bringing a firearm or weapon, as defined in chapter 790, to school, to any school function, or onto any school-sponsored transportation or possessing a firearm at school.
