You may qualify for reciprocity, a state to state certification exchange, if you meet Washington state's requirements.
To qualify for reciprocity you must:
- Meet Washington state education and experience requirements.
- Have passed a standardized Association of Boards of Certification (ABC) equivalent exam with a score of 70 percent or higher.
- Hold a valid certification in good standing.
- Pay the $50 application fee.
We have reciprocity with:
- Alabama, Alaska, Arizona, Georgia, Guam, Hawaii, Idaho, Iowa, Inter Tribal Council of Arizona, Massachusetts, Nevada, and Wyoming.
We have conditional reciprocity with:
- Oregon — if certification was received by taking a standardized ABC exam.
- Colorado — for levels A-D, not for class S.
- Utah — if certificate is not a restricted certificate.
- New York — if exam score is 70% or higher.
We do not have reciprocity with:
- California, Florida, Indiana, New Mexico, or North Carolina
If we do not have reciprocity with your state, you will have to meet Washington’s requirements and pass an exam to become a Washington State Certified Wastewater Operator.
Note: If you do not see your state listed above, we have not verified reciprocity with them.
