Answer: E, 58
The differences are 4, 7, 10, 13, 16; they rise by 3 each time. The next number is 58.
Check differences, then ratios. Make sure your rule fits every step.
Hiring test comparison
Both are 50-question, speed-based hiring tests that almost nobody finishes. The CCAT gives you 15 minutes and includes spatial reasoning; the PI Cognitive Assessment gives you 12 minutes and covers verbal, numerical and abstract reasoning. Most skills transfer between them. The pace does not.

The Criteria Cognitive Aptitude Test (CCAT), the hiring test from Criteria Corp, and the PI Cognitive Assessment from The Predictive Index look alike from a distance. Both measure general reasoning, both use 50 multiple-choice questions, and both are built so you run out of time. Up close they differ in the clock, the content and the score. Every row below is cited to the publisher's own public pages.

The time-per-question row is our arithmetic: 900 seconds over 50 questions, and 720 seconds over 50. It's the most important line in the table.
The PI test. Twelve minutes for 50 questions is 14.4 seconds each, against 18 seconds on the CCAT. That's 20% less time per question. Both publishers say the pressure is intentional. Criteria says fewer than 1% of candidates answer all 50 CCAT questionsC1. The Predictive Index says the number of questions answered correctly in the time frame determines the scoreP3, so every question you leave unreached is a point you can't get.
In practice, both tests reward the same decision: recognize a question you can't solve fast, guess, and move on. Criteria tells CCAT candidates to make an educated guess if a question takes more than a minuteC1. On the PI test a minute is the cost of four other questions, so your cutoff should be tighter still. If you've been practicing for the CCAT, run some sets at 12 minutes before a PI test. Our pacing calculator shows what a given score needs per minute.
Mostly. Criteria describes three CCAT areas: verbal ability (precise word meaning, how words relate, context), math and logic (basic algebra, proportions, word problems) and spatial reasoning (rotating or flipping shapes, recognizing patterns, and spotting the item that doesn't belong)C1. The Predictive Index describes verbal, numerical and abstract reasoningP1, and its help center says the questions cover "simple math, basic logic, and language comprehension"P3.
The clearest difference in the published descriptions is spatial. Criteria names rotations and mirror images; The Predictive Index's public pages describe abstract reasoning without listing those formats. If your test is the CCAT, practice rotations and reflections. If it's PI, focus on patterns and sequences. Our CCAT question types guide breaks the CCAT's three areas into formats you can drill.
Two examples of formats that fit both descriptions: a number sequence (numerical reasoning on PI, math and logic on the CCAT) and a visual sequence (abstract reasoning on PI, spatial reasoning on the CCAT).
What comes next? 8, 12, 19, 29, 42, ?
Answer: E, 58
The differences are 4, 7, 10, 13, 16; they rise by 3 each time. The next number is 58.
Check differences, then ratios. Make sure your rule fits every step.
Why it transfers. Sequence questions reward one habit on any test: write the differences, then the differences of those. More on the CCAT number series page.
Which tile comes next in the sequence?
Answer: B
Each step rotates 90° clockwise and swaps filled and empty cells. Apply both changes, not just one.
Track one changing feature at a time; check alternating positions.
Why it transfers. Visual sequences change one or two features per step. Track one feature at a time (position, rotation, fill) instead of the whole picture. See our CCAT spatial reasoning questions for more.
Both start with the same raw number: questions answered correctly. What employers see after that differs.
CCAT. Criteria sends employers your raw score out of 50 and your percentileC1, with sub-scores for its three areasC2. The percentile compares you with a reference group of adults. Criteria reports the average as 24 correctC1, and publishes suggested score ranges by job family. Our CCAT score guide lists them, and the CCAT score calculator estimates where a raw score sits.
PI Cognitive Assessment. The Predictive Index says the raw score is converted to a scaled score between 100 and 450P2, with verbal, numeric and abstract sub-scoresP3. The employer compares your result with a Cognitive Target, a level it sets for the job by rating what the role demandsP4. PI's own help center tells employers that cognitive data "is just one data point"P4.
You can't convert a CCAT raw score to a PI scaled score or back. Neither publisher offers a conversion, and the two tests are normed on different groups. Treat any online conversion table as a guess.
Retakes. On the CCAT, retakes are the employer's call. Criteria's default setting lets an employer reuse your result for up to 12 months if you apply againC4, and a different company will ask you to take its own testC3. For PI, the help center says candidates get up to three attempts, and that an expired or abandoned attempt counts as oneP3. PI's 2018 administrator guide also says it's up to the company whether to allow a retest, and that if a candidate tests more than once the decision should use the highest scoreP6. Plan for one sitting either way.
Extra time. Criteria's platform supports a 1.5x time adjustment, which makes the CCAT about 22 minutesC5. The Predictive Index offers 18-minute and 24-minute versions as reasonable accommodationsP1. On both, you ask the employer, not the publisher, and you ask before you start.
Results. Criteria emails CCAT results to the employer and doesn't share them with other companiesC3. PI results live in the employer's PI accountP3. Whether you see your score depends on the employer in both cases.
Employers choose a test as part of a hiring platform, so the test you get follows from the software the company already uses. Criteria sells the CCAT alongside its other assessments. The Predictive Index sells its cognitive test as part of a hiring platform where the employer first sets a behavioral target for the job, then a cognitive oneP4. So a PI invitation may include a behavioral questionnaire beside the cognitive test.
The invitation tells you which test you're taking. Look at the sender's domain and the test name. If it says Criteria or CCAT, it's the CCAT. For CCAT employers, our list of companies that use the CCAT shows what's public about each one's process, with sources.
What transfers between the two, and what doesn't:
Read your invitation's rules. PI's 2018 administrator guide suggests employers prohibit content "from an exam preparation company" specifically related to the PI testP6. That's general advice to employers, not a rule we've seen every company adopt, but check yours. General reasoning practice is a different thing from material about a specific test.
Clever Cat Prep is CCAT practice. If your test is the CCAT, start with a free timed CCAT practice test: 50 questions, 15 minutes, mixed like the real thing. If your test is PI, the same questions are still useful reasoning practice; set yourself a 12-minute clock. Our CCAT vs Wonderlic comparison covers the other test people confuse with the CCAT.

No. They are different tests from different publishers. The CCAT is from Criteria Corp; the PI Cognitive Assessment is from The Predictive Index. Both have 50 questions and a short time limit, but the PI test gives you 12 minutes and the CCAT gives you 15.
Neither publisher compares them, so no one can say for certain. The PI test gives you less time per question, 14.4 seconds on average against 18 on the CCAT. The CCAT includes spatial questions such as rotations and mirror images.
Much of it transfers: number sequences, quick arithmetic, word problems, analogies and visual pattern questions, and above all the habit of guessing and moving on under time pressure. Practice at a faster pace for PI, because its clock is shorter.
Neither publisher describes its test as adaptive. PI says it uses a linear-on-the-fly design that gives each candidate a unique set of items. Criteria says its large item bank means no two candidates get the same set.
The Predictive Index's help center says candidates get up to three attempts, and an expired or abandoned attempt uses one. Whether you are offered another attempt is up to the employer.
There is no universal one. PI scores run on a scale from 100 to 450, and each employer compares your result with a Cognitive Target it sets for the job. Ask the recruiter what the role requires.
No. Criteria says no calculators are allowed on the CCAT. The Predictive Index's 2018 administrator guide says the PI Cognitive Assessment instructions prohibit calculators.
