CREDENTIAL CYCLE: The credential cycle starts on the first day of the month that you took the test and will expire at the end of the two-year cycle. If the continuing education hours are met and the renewal fee is paid, it will be renewed for another 2 years. As an example, for someone who tested on March 15th, 2016, the credential cycle would go from 03/01/2016 to 02/28/2018. For those who do not meet the continuing education requirement or pay the renewal fee (following the 60-day renewal grace period), the credential is revoked.
