Process operator

About this practice suite

This suite prepares candidates for process operator selection in the energy, utilities, nuclear, mining, and natural resources sector with 5 skill areas: technical reasoning, numerical reasoning, situational judgment, mechanical comprehension and safety judgment. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

• Technical reasoning — Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Situational judgment — Evaluating workplace responses against role-relevant principles.
• Mechanical comprehension — Forces, motion, gears, pulleys, levers, fluids, pressure, and basic machines.
• Safety judgment — Hazard recognition, safe sequencing, escalation, and risk controls.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.

1. A process operator's primary board/field role is to:

   • A. Run continuous plant units within safe operating envelopes
   • B. Design corporate tax strategy
   • C. Retail finished consumer goods
   • D. Ignore interlock logic

2. Column differential pressure rises while feed is steady. What is best?

   • A. Bypass reboiler steam blindly
   • B. Increase feed to 'push through'
   • C. Disable DP alarms
   • D. Diagnose flooding/fouling/restriction; adjust within SOP before trip

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
