GATB content outline and where to practise each area

The content areas below are copied from the official GATB content outline published by U.S. Department of Labor, Employment and Training Administration / National Center for O*NET Development. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through GATB questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: Which of the following occupations would most heavily rely on a high level of Form Perception?

1. Social Worker
2. Drafter
3. Radio Announcer
4. Heavy Equipment Operator

Answer: B. Drafter

Explanation:

Drafter is correct. Form perception is the ability to notice small differences in the shapes, lines and shading of objects and drawings. A drafter makes detailed technical drawings and has to catch slight errors in line length, angle or shape, so this ability is central to the job.

• Social Worker relies mostly on verbal and interpersonal skills. Form perception plays a minor role.
• Radio Announcer depends on verbal ability: reading, speaking and choosing words.
• Heavy Equipment Operator relies more on motor coordination and spatial ability, judging how a machine moves through space.

Rule to remember: form perception means seeing fine detail in pictures and objects. Clerical perception is the same kind of skill applied to words and numbers.

Example 2

Question: Employees of a discount appliance store receive an additional 20% off the lowest price on any item. If an employee purchases a dishwasher during a 15% off sale, how much will he pay if the dishwasher originally cost $450?

1. $280.90
2. $287.00
3. $292.50
4. $306.00

Answer: D. $306.00

Explanation:

$306.00 is correct because the discounts apply one after the other. First, take 15% off the original $450 to get the sale price. The employee's extra 20% then comes off that lower sale price, because the question says it applies to the lowest price on the item. Doing the steps in that order gives $306.00.

• $292.50 is the trap. It comes from adding the two discounts together and taking them off $450 at once. That overstates the saving, because the 20% should apply to a smaller amount.
• $287.00 and $280.90 match neither method. They usually come from an arithmetic slip or from taking the second discount off the wrong price.

Rule to remember: when discounts stack, apply each one to the price left after the one before. Never add the percentages together.

Example 3

Question: In the series 1, 4, 9, 16, 25, what comes next?

1. 30
2. 33
3. 36
4. 39

Answer: C. 36

Explanation:

36 is correct. Each term in the series is a whole number multiplied by itself: 1, 4, 9, 16 and 25 are the squares of the counting numbers in order. Squaring the next counting number gives 36. You can also check the gaps between terms. Each gap is bigger than the last by the same amount, and continuing that pattern from 25 lands on 36.

• 30 and 33 come from adding too small a step after 25, as if the gaps had stopped growing.
• 39 adds too large a step.

None of the three wrong options is a perfect square, which is a quick way to rule them out. Rule to remember: when a series grows faster and faster, test for squares first, then look at the differences between terms.

If you want more targeted practice, the gatb test page covers the same material with additional questions and explanations.

How to use these practice tests

First, ask your test site which parts your session includes, and in particular whether it uses the apparatus component. The answer tells you which areas need hands-on preparation and which do not.

Next, do a short first pass through the sets on this page: Arithmetic Reasoning, Computation, Verbal Aptitude, Spatial Aptitude, Form Perception and Clerical Perception. Note which areas feel slow or uncertain. Spend most of your later sessions on those, and go back to your stronger areas only to keep them fresh.

Every part is timed separately, so practise keeping a steady pace. Time yourself on each set, answer what you can, and skip any item that holds you up. After each set, go over every miss and write down the rule behind it, such as applying discounts in order or checking every character when comparing names.

For the dexterity areas, read the official task descriptions so you know what the tasks involve. Our questions can explain the tasks but cannot replace hands-on practice. Before test day, read the official examinee instructions, rest well, and bring whatever your test site asks for.

• Topics: Folding, rotation
• Questions: 40 Questions
