R.I. Gen. Laws § 5-64-13
All licenses under this chapter shall be renewed biennially and shall be accompanied by a fee of one hundred twenty-five dollars ($125). The application shall be accompanied or supported by evidence of the completion of a minimum of twenty (20) continuing-nutrition-education credits as approved by the board, reported biennially every second year after the 1993 recertification period. Failure to file an application for a renewal license to practice and to furnish the evidence shall constitute grounds for revocation, suspension, or refusal to renew the license, unless the board of dietetics, in its discretion, determines the failure to be due to reasonable cause or excusable neglect. This applicant shall be given six (6) months to make up the appropriate amount of credits required to bring him or her into compliance. Thereafter, the candidate shall be subject to immediate suspension or revocation of license.
