Applying for an Exam
Students wishing to test for their certifications MUST apply to the Oklahoma Department of Environmental Quality (DEQ) no later than 3 weeks before the start date of a class. Failure to do so will prevent students from being able to test and become certified. Payment to DEQ must be included with the application. The fee is non-refundable and non-transferable and is good for up to 120 days. After that period, the application fee is forfeited. For more information, please visit the DEQ website at https://www.deq.ok.gov/water-quality-division/operator-certification/
