What is the CAST Exam?

The CAST is a battery of tests used to gauge an applicant’s aptitude and ability to learn and process new information, which provides an indication of the likelihood of success on the job.

The exam is a typical component of the employment application process for individuals seeking employment in industry jobs such as facility maintenance and repair, transmission and distribution, electrical repair, machine maintenance and repair, vehicle maintenance and repair, meter service and repair, and other skilled trades.

Exam Outline Review

The CAST exam consists of four paper-and-pencil aptitude tests that take approximately 1.5 hours to complete:

1. Graphic Arithmetic (16 questions)

This test measures your ability to solve arithmetic problems based on information from prints and drawings. You will encounter a lot of floor plans, blueprints, and other types of drawings and prints that are relevant to construction and skilled trades.

You will have 30 minutes to answer the 16 questions on this test, which will cover the following skills:

  • Basic arithmetic (addition, subtraction, multiplication, division, etc.)
  • Elementary algebra (based on high school level algebra curriculum)
  • Interpretation of visual information

2. Mechanical Concepts (44 questions)

This test will focus on your ability to work with fundamental mechanical concepts that are most relevant to construction and other skilled trade jobs. Each question will include a visual representation of a mechanical situation and three possible answers.

You will have 20 minutes to complete the 44 multiple-choice questions, which cover a range of everyday mechanical principles:

  • Gravity
  • Levers
  • Pulleys
  • Gears
  • Shapes
  • Centrifugal Force

3. Reading for Comprehension (32 questions)

The reading for comprehension test assesses exactly what its name implies: your reading and comprehension skills.

The test is made up of four separate reading passages, which are each followed by a series of multiple-choice questions related to the passage you just read. You will have 30 minutes to answer 32 questions, all of which measure how much of the text you understood and retained.

4. Mathematical Usage (18 questions)

The 18 questions in this test will be focused on the math that you would be most likely to use in the day-to-day duties of your job, and you will have 7 minutes to complete the test.

You’ll need to brush up on the following subjects:

  • Basic arithmetic including addition, subtraction, multiplication, and division
  • High-school-level algebra
  • Measurements, including the ability to convert between different kinds of measurements

Registration

While the CAST exam is the same no matter where you take it, it’s not administered by any central organization. Instead, the company where you are applying for the job will administer the test to you. Because of this, registering for it is just a matter of scheduling an appointment with your potential employer to take the test.

Test Day

There are a few general guidelines that will hold true no matter where you are taking the test. Those guidelines include:

  • The test will always be pencil-and-paper-based.
  • The full exam will last roughly 90 minutes.
  • No calculators, dictionaries, or other study aids will be allowed in the exam room.
  • Everything that you will need for the test will be provided for you so you don’t need to bring anything except your photo ID.
  • Any questions you have about the exam need to be asked before you begin taking it.
  • It’s advisable to show up 15-30 minutes before your actual appointment to check in.

How the Test is Scored

The results of these four tests are combined to provide a single index score ranging from 1 to 10. There is no defined “passing score” since each individual company can set its own score minimums.

Scoring well on the CAST indicates an ability to learn and perform the job due to an understanding of mathematical relationships, possession of good analytical skills, and attention to detail. Since you are competing against other applicants and scoring well does not guarantee employment, you will want to achieve as high a score as possible.

How to Study for the CAST Exam

How to Study Effectively

Your success on CAST test day depends not only on how many hours you put into preparing but also on whether you prepared the right way. It’s good to check along the way to see whether your studying is paying off. One of the most effective ways to do this is by taking CAST practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a free CAST exam practice test, pay special attention to these three groups of questions:

  • The questions you got wrong
  • The ones you had to guess on, even if you guessed right
  • The ones you found difficult or slow to work through

This will show you exactly what your weak areas are and where you need to devote more study time. Ask yourself why each of these questions gave you trouble. Was it because you didn’t understand the material? Was it because you didn’t remember the vocabulary? Do you need more repetitions on this type of question to build speed and confidence? Dig into those questions and figure out how you can strengthen your weak areas as you go back to review the material.

Answer Explanations

Additionally, many CAST practice tests have a section explaining the answer choices. It can be tempting to read the explanation and think that you now have a good understanding of the concept. However, an explanation likely only covers part of the question’s broader context. Even if the explanation makes sense, go back and investigate every concept related to the question until you’re positive you have a thorough understanding.

Comprehend Each Topic

As you go along, keep in mind that the CAST practice test is just that: practice. Memorizing these questions and answers will not be very helpful on the actual test because it is unlikely to have any of the same exact questions. If you only know the right answers to the sample questions, you won’t be prepared for the real thing. Study the concepts until you understand them fully, and then you’ll be able to answer any question that shows up on the test.

Strategy for CAST Practice

When you’re ready to start taking practice tests, follow this strategy:

  • Remove Limitations. Take the first test with no time constraints and with your notes and CAST study guide handy. Take your time and focus on applying the strategies you’ve learned.
  • Time Yourself. Take the second practice test “open book” as well, but set a timer and practice pacing yourself to finish in time.
  • Simulate Test Day. Take any other practice tests as if it were test day. Set a timer and put away your study materials. Sit at a table or desk in a quiet room, imagine yourself at the testing center, and answer questions as quickly and accurately as possible.
  • Keep Practicing. Keep taking practice tests on a regular basis until you run out of practice tests or it’s time for the actual test. Your mind will be ready for the schedule and stress of test day, and you’ll be able to focus on recalling the material you’ve learned.
