What is the purpose of the Operator-In-Training certificates?
The Operator-In-Training Basic certificate is intended to recognize individuals who are just beginning a career in the wastewater treatment field. This examination stresses basic general knowledge of wastewater treatment processes. The Operator-In-Training Intermediate and Advanced certificates are intended to provide an alternative route for obtaining Class 2 certification for operators at activated sludge facilities located in large metropolitan areas. These examinations stress the activated sludge treatment processes rather than the treatment processes included on the Class 4 and Class 3 examinations since these operators are not familiar with the operation of lagoons, trickling filters, packed towers, etc.
