Practice benchmark only: the Texas TCEQ Class D Wastewater examination is a computer-based test at TCEQ-registered testing centers across Texas. TCEQ’s general examination rule sets the minimum passing score for an examination at 70%. This practice exam is scored to that same 70% standard and flags 70% as a PRACTICE BENCHMARK ONLY — set to mirror the general published standard; its 100-question draw is this practice program’s own format, run on a 180-minute clock, mirroring the real exam’s published 3-hour limit. It is a study signal, not a TCEQ result.
