No law enforcement officer employed or appointed on or after July 1, 1989, by any public law enforcement agency in this State is authorized to enforce the laws or ordinances of this State or any political subdivision thereof unless he has been certified as qualified by the Department of Public Safety, except that any public law enforcement agency in this State may appoint or employ as a law enforcement officer, a person who is not certified if, within one year after the date of employment or appointment, the person secures certification from the department; provided, that if any public law enforcement agency employs or appoints as a law enforcement officer a person who is not certified, the person shall not perform any of the duties of a law enforcement officer involving the control or direction of members of the public or exercising the power of arrest until he has successfully completed a firearms qualification program approved by the department; and provided, further, that within three working days of employment the department must be notified by a public law enforcement agency that a person has been employed by that agency as a law enforcement officer, and within three working days of the notice the firearms qualification program as approved by the director must be provided to the newly hired personnel. If the firearms qualification program approved by the director is not available within three working days after receipt of the notice, then the public law enforcement agency making the request for the firearms qualification program may employ the person to perform any of the duties of a law enforcement officer, including those involving the control and direction of members of the public and exercising the powers of arrest. Should any such person fail to secure certification within one year from his date of employment, he may not perform any of the duties of a law enforcement officer involving control or direction of members of the public or exercising the power of arrest until he has been certified. He is not eligible for employment or appointment by any other agency in South Carolina as a law enforcement officer, nor is he eligible for any compensation by any law enforcement agency for services performed as an officer. Exceptions to the one-year rule may be granted by the director in these cases:

1. (a) military leave or injury occurring during that first year which would preclude the receiving of training within the usual period of time; or
2. (b) in the event of the timely filing of application for training, which application, under circumstances of time and physical limitations, cannot be honored by the training academy within the prescribed period; or
3. (c) upon presentation of documentary evidence that the officer-candidate has successfully completed equivalent training in one of the other states which by law regulate and supervise the quality of police training and which require a minimum basic or recruit course of duration and content at least equivalent to that provided in this article or by standards set by the South Carolina Department of Public Safety; or

4. (d) if it is determined by documentary evidence that the training will result in undue hardship to the requesting agency, the requesting agency must propose an alternate training schedule for approval.

   Notwithstanding another provision of law, in the case of a candidate for certification who begins one or more periods of state or federal military service within one year after his date of employment or appointment, the period of time within which he must obtain the certification required to become a law enforcement officer is automatically extended for an additional period equal to the aggregate period of time the candidate performed active duty or active duty for training as a member of the National Guard, the State Guard, or a reserve component of the Armed Forces of the United States, plus ninety days. The director must take all necessary and proper action to ensure that a candidate for certification as a law enforcement officer who performs military service within one year of his employment or appointment is not prejudiced in obtaining certification as a result of having performed state or federal military service.
