How long do I have to complete the CAST test?

The CAST (Construction and Skilled Trades) test has a total testing time of approximately two hours. The exam is divided into multiple timed sections, each covering different skill areas. Time limits vary by section, so it is important to pace yourself and not spend too long on any single question during the assessment.

What topics are covered on the CAST exam?

The CAST exam covers four main areas: graphic arithmetic, mechanical concepts, reading for information, and mathematical usage. Graphic arithmetic involves solving problems using charts and figures. Mechanical concepts test your understanding of physical principles like levers, pulleys, and gears. Reading for information assesses your ability to interpret workplace documents and technical instructions.

Who is eligible to take the CAST test?

Eligibility for the CAST test is determined by the employer requesting it as part of their hiring process. There are no universal age or education prerequisites set by the test publisher. Typically, candidates applying for apprenticeships or entry-level positions in utilities, power generation, or skilled trades will be asked to complete the CAST as a pre-employment screening tool.

How do I register for the CAST test?

Registration for the CAST test is handled through the employer or utility company requiring it. You do not register independently with the test publisher. After applying for a position, the employer will provide instructions on when and where to take the exam, often through a third-party testing center like PSI or Prometric, or at the employer's own facility.

What score do employers typically look for on the CAST?

Most employers set their own minimum score thresholds, but a score at or above the 50th percentile is generally considered competitive. Some utilities and trade companies require scores in the 70th percentile or higher for consideration. Your raw scores are converted to scaled scores and compared against a norm group of other test takers in similar job categories.

Can I retake the CAST test if I want a higher score?

Retake policies are set by each employer individually. Some companies allow candidates to retake the CAST after a waiting period of six months to one year. Others may only permit one attempt per hiring cycle. Check directly with the employer or their HR department for specific retake policies and any applicable waiting periods before scheduling another attempt.

Are the questions on the CAST multiple choice?

Yes, the CAST test consists entirely of multiple-choice questions. Each question presents four answer options, and you must select the best answer. Some sections include diagrams, charts, or illustrations that you need to interpret in order to answer correctly. There is no written essay portion or hands-on practical component included in the CAST assessment.

Do I need prior trade experience to pass the CAST?

No formal trade experience is required to pass the CAST. The test measures aptitude and foundational skills rather than specialized trade knowledge. However, a basic understanding of mechanical concepts, comfort with arithmetic, and strong reading comprehension will help you perform well. Candidates who review fundamental math and physics principles before testing day tend to score significantly higher.
