How Georgia classifies drinking-water operators

Georgia certifies operators through the State Board of Examiners under the Secretary of State's Professional Licensing Boards (applications through the GOALS system), with plant classes assigned by Georgia EPD.

Public Water Supply System Operator (Classes IV–I)

Georgia wastewater practice tests

Georgia's biological wastewater ladder runs OPPOSITE the national numbering: Class IV (waste stabilization ponds only) is the entry and Class I is the highest. Industrial wastewater is a separate single-class license (27-hour course). Match your class by the card titles, not the test numbers.

GA Board · Class IV (ponds)

Georgia Class IV Wastewater Practice Test

Georgia's Class IV wastewater license covers waste stabilization pond systems only, entered through a 6-hour pond operator course and one month of experience. This dedicated pond bank matches that scope exactly: pond biology and algae, facultative lagoons, controlled discharge, troubleshooting, and pond math.

44 questions~44 min
GA Board · Class III

Georgia Class III Wastewater Practice Test

Georgia's standard wastewater entry: a 40-hour basic wastewater course and three months of experience, testable before the experience is complete. Remember the inverted ladder: III is near the bottom, I is the top.

119 questions~143 min
GA Board · Class II

Georgia Class II Wastewater Practice Test

Class II requires holding a Class III, 48 hours of advanced wastewater courses, and 24 months of experience (less with a science degree), completed before exam eligibility.

109 questions~131 min
GA Board · Class I (highest)

Georgia Class I Wastewater Practice Test

Georgia's highest biological wastewater license: hold a Class II plus 36 months of experience (24 with a bachelor's in biology or chemistry). Class I through III biological operators may also run collection systems and industrial wastewater plants without further certification.

114 questions~171 min
Extra practice

Georgia Class II to I — Extra Practice

An additional advanced bank for the climb from Class II to Class I: process control, nutrient removal, solids handling, and management material.

About the Georgia operator exams

Operator certification in Georgia covers several disciplines — drinking water, wastewater, distribution, and collections — which may be handled by the same agency or by separate programs (drinking water is administered by Georgia State Board of Examiners (Secretary of State) — Water & Wastewater Operator Certification). The exact certification structure, exam format, levels, and continuing-education requirements vary by discipline and change over time, so always confirm the current scope and eligibility directly with the certifying agency. Our practice content focuses on the underlying technical material — the same operating principles, math, regulations, and process knowledge that show up on water and wastewater operator exams nationwide.

Frequently asked questions

How does Georgia classify water operators?
Georgia certifies operators through the State Board of Examiners under the Secretary of State's Professional Licensing Boards (applications through the GOALS system), with plant classes assigned by Georgia EPD. The numbering runs OPPOSITE the national convention: Class I is the highest license and Class IV the entry, for both Public Water Supply and Biological Wastewater operators. Water adds a Class IIIG groundwater-only variant, wastewater Class IV covers waste stabilization ponds only, and single-class licenses cover Water Distribution, Wastewater Collection, Industrial Wastewater, and Water and Wastewater Laboratory Analysts. The ladder: enter directly at Class IV (6-hour course, one month of experience) or Class III (40-hour course, three months); above that it is sequential, with Class II requiring 48 hours of advanced coursework and 24 months of experience and Class I requiring 36 months, and science degrees shorten the experience (a bachelor's in biology or chemistry cuts Class I to 24 months). A Georgia quirk helps new operators: for Class IV, III, and all single-class licenses you may take the exam before finishing the experience, but Class II and I require the experience first, and you must apply for the certificate within 12 months of passing. Exams are WPI-standardized, computer-based at PSI, offered at least six times a year; Georgia publishes no official crosswalk between its inverted classes and the WPI exam classes, so match by the class named on each card. Upper licenses carry built-in cross-coverage: Class I through III water operators may run distribution systems, and Class I through III biological wastewater operators may run collection systems and industrial plants, without the separate licenses. Certificates renew every two years, expiring June 30 of odd-numbered years, on continuing education points that scale with class: 24 for Class I, 18 for Class II, 12 for Class III and the single-class licenses, 6 for Class IV, with at least half discipline-approved, only the highest certificate's requirement applying when you hold several, and upgrading voids the lower certificate. Reciprocity is certification by endorsement for substantially similar out-of-state licenses, no exam required, with expedited handling for military families.
Are these the exact questions on the Georgia exam?
No. These are independent practice tests designed to mirror the technical material and difficulty of the Georgia certification exam. The official exam is administered by Georgia State Board of Examiners (Secretary of State) — Water & Wastewater Operator Certification (or its testing vendor) and the exact questions are not public.
Are these practice tests free?
Yes. Every practice test on this site is 100% free, and always will be. To keep it that way, the site may feature sponsors or offer optional paid resources like study courses, but the practice tests themselves stay free.
