N.Y. Comp. Codes R. & Regs. tit. 9, § 6025.7 – Time limitations for completion of the basic course for peace officers.

(a) Every person appointed as a peace officer shall forfeit such position unless he or she has received, within one year from his or her date of original appointment, a certificate of satisfactory completion of a basic course for peace officers approved by the commissioner.
(b) A peace officer who, because of exigent circumstances, is unable to complete a basic course within the one-year time period prescribed in subdivision (a) of this section may apply through his or her employer for an extension of this period by the commissioner. Such applications shall be made in writing and must describe the circumstances which necessitate the application. Illustrative of exigent circumstances are: the officer’s inability to complete a basic course for heath reasons or the temporary unavailability of a training program within a reasonable distance from the officer’s place of employment. If the commissioner determines that the circumstances warrant extension of the one-year period, he or she may grant approval of such extension. In no instance shall this period be extended beyond a total of two years from the initial date of appointment as a peace officer, except as otherwise required by law.
(c) No employer shall allow any peace officer, notwithstanding when the officer was appointed, to carry or use a weapon during any phase of the officer’s official duties, which constitutes on-duty employment, unless the officer has within 12 months after appointment satisfactorily completed a course of training as prescribed in section 6025.3(c) of this Part, and annually thereafter receives instruction in deadly physical force and the use of firearms and other weapons as approved by the council.
