Grade 4 sample question

Administration: maintenance performance · an original practice item written only from publicly available sources, not a real exam question

Your shop scheduled 230 preventive maintenance work orders this quarter and completed 184 of them on time. What is the preventive maintenance compliance rate?

20%
46%
80%
125%

Answer and working

C. 80%

Compliance = completed on time ÷ scheduled × 100 = 184 ÷ 230 × 100 = 80%. 125% inverts the ratio, 20% is the miss rate, and 46 is the count of missed work orders reported as if it were a percentage.

EIT Candidate Handbook, CWEA (effective April 2022)

Topic coverage follows Electrical & Instrumentation Technologist Candidate Handbook, Version 04.25.22.01 (California Water Environment Association, effective April 2022). Practice questions are written only from publicly available sources (that outline and the regulations and references it cites); they are not real exam questions, which are confidential. Check current application requirements, fees and exam dates on the certifying body's own page: official certification page.

Questions, flashcards, and explanations are AI-written from publicly available sources only: the exam content outlines and candidate materials each certifying body publishes without restriction, and the regulations and technical references they cite. No confidential material is used, including actual exam questions, recollections of any exam sat by the author, or any handbook or document released under a confidentiality agreement. Content is then put through repeated review — regulatory values checked against primary sources, every calculation recomputed, and errors corrected — plus spot checks by the author, who holds California water operator certifications and a California civil engineering licence. Those spot checks are sampling, not a professional review: nothing here is stamped, sealed, or offered as engineering advice, and not every item has been individually verified, so mistakes can still slip through.
