Evaluation Schedule

To maintain current certification, on-site evaluations shall be performed at an approximate interval of 12 months. The frequency of the on-site evaluation shall not exceed 14 months. Once the date of the initial evaluation is scheduled, a reasonable attempt will be made to keep the evaluations within the same month each year. If the evaluation does not take place within the regularly-scheduled month for a particular calendar year, it is expected that the evaluation will take place on the regularly scheduled month the following calendar year. (This could reduce the frequency between two consecutive evaluations to ten months in some instances.) The scheduled month for each center currently in the program is listed in the schedule below.
