R.I. Gen. Laws § 12-2.1-6
Any individual who has been appointed as a police officer in a sister state or one of its municipalities and who has satisfactorily completed a required course of police officer training recognized and certified by the sister state may apply, in writing, to the superintendent of state police for a certificate to the effect that the applicant has completed a course of training equivalent to that required under § 12-2.1-1. The application may be granted in whole or in part or denied. If granted in part, the exact extent of both any waiver of training and the training yet to be satisfactorily completed shall be set forth in full. The certification shall be granted only if the superintendent determines that the course of training previously taken, together with the satisfactory completion of any training not waived, is in compliance with and equivalent to the training required by § 12-2.1-1.
