License Renewals

The O&M Specialist License expires on December 31. Fees are not prorated. At the end of each year, an invoice for renewal is generated.

A licensed O&M Specialist must provide three continuing education units (CEUs) in three years in his field. This verification must be provided no later than December 31st of each third year of being licensed. A person may take as many hours as they wish and it can be applied to future years, not to exceed three years.

Come January 31, if you fail to pay your renewal fee and provide a copy of your bond (if expired), your license will expire and can not be renewed.  Also following the third year of being licensed, should you fail to provide verification of CEUs, your license will not be renewed and will have expired effective December 31.

If you want to be licensed again, all testing, application and fees must be completed again to be reinstated.
