Is it a knowledge test?

No, and Criteria is careful about the distinction: it measures aptitude, the ability to learn mechanical work, rather than what you already know about it. The items are written at an estimated sixth-grade reading level, so nothing in them depends on trade vocabulary you have not met.

As a raw score plus a percentile ranking. The raw score is simply how many of the 60 you answered correctly; the percentile places that against everyone else who has taken it. Criteria publishes no passing score, because the employer sets its own.

Is a Spanish version available?

Criteria says there is one. If English is not your first language, it is worth asking the employer which version you will be given before test day rather than after.

Wiesen test of mechanical aptitude

The WTMA is the other test an employer is likely to send, published by Criteria Corp — the same company behind the CCAT. Criteria publishes its shape as a 30-minute, 60-item test measuring “mechanical aptitude, or ability to learn to use and maintain equipment and machinery”, scored as a raw count out of 60 plus a percentile. This page runs sixty questions in thirty minutes for that reason.

60 questions. 30 minutes.

That is 30 seconds a question. The clock starts when you press the button and submits the test when it runs out. You will not be told whether an answer was right until the end — that is the point of a timed run.
