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 in a particular calendar year, it is expected that the evaluation will take place during the regularly scheduled month the following calendar year. In some instances, this may reduce the frequency between consecutive evaluations to ten months. Please contact us if you have any questions regarding the on-site evaluation schedule.
