In South Dakota we allow willing school employees to carry a concealed firearm after completing extensive background checks and law enforcement training. To my knowledge there are two school districts in the state that have utilized what is called the School Sentinel Program. The program works like this:
School Sentinel Training Program
The school board may submit a person for school sentinel training only if the person meets the following requirements:
1-Is a citizen of the United States;
2-Is at least 21 years of age at time of appointment;
3-Has fingerprints taken by a qualified law enforcement officer;
4-Is of good moral character;
5-Is a graduate of an accredited high school or has a high school equivalency certificate acceptable to the commission;
6-Is examined by a licensed physician who certifies, on forms prescribed by the commission, that the applicant is able to perform the duties of a school sentinel;
7-Is interviewed in person by the school board or its designee and approved by the school board to apply to the school sentinel basic training course;
8-Has received written approval to apply to the school sentinel basic training course by all local law enforcement agencies with jurisdiction over the school premises in which the individual will act as a school sentinel;
9-Has not unlawfully used any prescribed drug, controlled substance, or marijuana within one year before the time of application for training; and
10-Has a valid concealed weapons permit.
Law Enforcement Training provides training for all approved school sentinels. The training course for the school sentinel program consists of at least 80 hours of training in the following subject areas.
1-Firearms proficiency
2-Use of force
3-Legal aspects
4-Weapons retention
5-Identifying protocol for identifying sentinel
6-First aid
No employee can be required to participate in the School Sentinel Program against their will.
13-64-4. School employee right to refuse to carry firearms. No school board, in implementing the provisions of § 13-64-1, may arm any individual teacher or other school employee without the latter's free, willing, and voluntary consent. No individual teacher or other school employee may be censured, criticized, or discriminated against for unwillingness or refusal to carry firearms pursuant to this chapter.
