Verified pass standard: the California SWRCB Wastewater Treatment Plant Operator Grade V exam is scored on 140 points — 25 multiple-choice questions at 2 points, 29 multiple-choice essay questions at 2 points, and 16 mathematics questions at 2 points — in a 4-hour computer-based sitting, and the board’s Grade V examination information sheet (Rev. 2/2021) states the passing standard plainly: at least 98 of 140 points (70%) overall AND at least 16 of 32 points (50%) on the mathematics questions. This practice exam is scored at that same 70% overall mark on a 100-question four-option draw running on a 180-minute practice clock; the practice draw carries no separate mathematics sub-score. It is a study signal, not an SWRCB result.
