Guess or skip? What each publisher actually says

On two of the three big hiring tests a blank answer is a wasted point. On the third, the publisher tells you guessing is not likely to help. Mixing them up costs you either way.

The three rules, side by side

Read as of October 2026. If the instructions on your own test screen say something different, follow the screen.

The math of a guess

When a wrong answer and a blank are both worth zero, a guess can only help. How much?

Two extra correct answers does not sound like much. On the CCAT, where the average is 24 and the spread is 7 (Criteria Information Brief), two points near the middle is a move of roughly ten percentile places. And an educated guess is worth far more than a blind one: getting from five choices down to two takes a few seconds on many questions and turns a 20% chance into 50%.

The more important number is time. A guess takes two seconds. Grinding on a question you are not going to solve takes 60. On an 18-second-per-question test, those 58 seconds are three more questions you could have read, and some of them would have been easy.

The two-second rule

You need to decide fast whether a question deserves your time, because deciding slowly is itself the cost. Here is the rule we teach:

1. Read the question once.
2. Ask: do I see how to start? You have about two seconds for an honest yes or no. Not "could I work it out eventually", but "do I know my first step right now".
3. Yes: solve it, up to your ceiling (about 30 seconds on a 12-minute test, 35 to 40 on the CCAT).
4. No: spend three to five seconds crossing out choices that are clearly wrong, then apply the rule for your test (below) and move on.
5. Hit the ceiling mid-solve: same thing. Take the best of what is left. Do not restart.

This feels wrong the first few times, because it means walking away from questions you could solve with more time. That discomfort is the skill. It takes one or two timed practice tests to get used to it, which is one of the best reasons to take them.

On the CCAT

The clearest case. No penalty, and prep vendors consistently report you cannot return to a question once you move on, so a blank can never be fixed later. Every question you leave gets an answer.

• At "no" in the two-second rule: eliminate what you can, pick, go.
• Criteria's own limit is one minute on a question before you make an educated guess. Treat that as the outer wall, not the plan.
• When the timer shows 20 seconds, answer the question in front of you whether or not you have finished reading it.

One caution. Criteria's Score Report Guide describes a flag for candidates who go through the test very fast with no errors, which the system reads as prior familiarity with that version. That is about suspiciously perfect speed, not about guessing; ordinary guess-and-move-on pacing is exactly what Criteria recommends to candidates.

On the PI Cognitive Assessment

Same logic, with one extra tool. The test shows five questions per page and lets you move between pages with Previous and Next. So a guess does not have to be final:

• At "no" in the two-second rule: mark your best choice immediately, so the question is never blank, and note its number on your scratch paper if you are allowed one.
• Keep going to the end of what you can reach.
• If time remains, return to the noted questions. Most people will not have time, and that is fine; the answer is already in.
• With four choices instead of five, each blind guess is worth a quarter of a point on average. In the last 30 seconds, click an answer for anything still empty on the pages you have seen.

The publisher is explicit that the score depends only on the number of correct answers: "the more questions answered correctly, the higher the respondent's score."

On the Wonderlic

Here the publisher's instruction is different, and we follow it.

Wonderlic tells candidates that guessing is not likely to improve the score. It does not publish how the cognitive section of Wonderlic Select is scored, so we do not claim there is a penalty for wrong answers and we do not claim there is none. What we can say is what the instructions ask for:

• If you think you know the answer but are not sure, mark your best choice and move on. That is an educated choice, and Wonderlic endorses it. If you have narrowed a question to two choices, answer it.
• Do not skip around. Take the questions in order. Do not hunt for easy ones.
• Do not spend too much time on any one question. The ceiling still applies: about 30 seconds.
• Do not spray random answers at the end. When time is nearly up, finish the question you are on properly instead of clicking through five you have not read.

So what do you do at "no" in the two-second rule? Give it your three to five seconds of elimination. If that leaves you with a real preference, mark it. If you have no idea at all, the instructions give you no reason to expect anything from a blind pick; choose quickly and move to the next question, and do not let it take more of your clock. The loss you can control on the Wonderlic is time, not that single answer.

You will find prep sites that tell you to guess on everything on the Wonderlic "because there is no penalty". That may describe older versions of the test, where the score was simply the number correct. It is not what the publisher tells candidates today, and we would rather give you the publisher's rule.

If you do not know which test you have

Find out; it takes two minutes with the invitation email. If you truly cannot, read the instructions screen before the clock starts: a sentence about wrong answers or guessing is nearly always there. Without any information, the cautious default is the Wonderlic approach: work in order, commit to educated choices, skip the random clicking.

Practice the decision, not just the questions

Knowing the rule and applying it at second 25 of a stubborn question are different things. A timed practice test shows you how you actually behave: on TimedPrep, the result page lists your time on each question, so the ones where you spent 50 seconds and still got it wrong are easy to spot. The first full test in each format is free, with no sign-up.
