Education and Training

Requirements for operator certification are specified by the state. Each state has the authority to develop their own requirements for operator certification. The guidelines required that states must require the following for an operator to become certified:

  • Take and pass an exam that demonstrates that the operator has the necessary skills, knowledge, ability, and judgement as appropriate for the classification.
  • Have a high school diploma or a general equivalency diploma (GED). States may allow experience and/or relevant training to be substituted for a high school diploma or GED.
  • Have the defined minimum amount of on-the-job experience for each appropriate level of certification. The amount of experience required increases with each classification level. Post high school education may be substituted for experience. Credit may be given for experience in a related field (e.g., wastewater).
  • The state must establish training requirements for renewal based on the level of certification held by the operator. States must require all operators including grandparented operators to acquire necessary amounts and types of state approved training. States may determine other requirements as deemed necessary. States must have a fixed cycle of renewal not to exceed three years.
