ASVAB Assembling Objects

The Assembling Objects (AO) section of the ASVAB (Armed Services Vocational Aptitude Battery) exam measures your ability to comprehend and remember connections between objects and analyze their spatial relationships. The Navy is the only branch of the Military that uses this subtest to identify individuals with the qualifications needed for a select number of jobs.

Test Delivery Method

There are two delivery methods for the ASVAB – by computer (CAT-ASVAB) and by paper (P&P-ASVAB). Which version of the exam you take depends on where you take the exam. The computer exam is self-paced. The paper exam is conducted in a group, with each test-taker advancing to the next section only when everyone has completed the current section.

Question Format

Assembling Objects is a subtest of the two hour and 34-minute ASVAB exam. You have 15 minutes to complete the computer-delivered version or 16 minutes to complete the paper version. You cannot take the AO subtest on its own. There are 25 multiple-choice questions in the AO subtest, divided into two categories – connection items and puzzle items.

Connection items consist of shapes and lines labeled, indicating the points of attachment. You must select from four possible answers the most accurate representation of the connection of the two shapes. These problems may require you to rotate or move the objects in a clockwise or counter-clockwise movement to achieve the correct response.

Puzzle items consist of multiple shapes that you connect to create a new shape. These questions require you to mentally rotate or move the shapes to connect them to form a new geometric shape. Like the connection problems, you will have to turn or move the images to create new shapes.

Process of Elimination

There are two timesaving methods to eliminate answers. The first is that no answer contains a mirror image. Glance through the listed answers. If it includes a mirror image, that answer is not correct. The second is to identify the answers that do not have the example diagram’s shapes or dots. The correct answer always has the same shapes, albeit in different positions, then the example diagram contains. Using the process of elimination allows you to quickly reduce the number of possibilities, which, in turn, saves precious time identifying the correct answer.

Registration and cost

There are two ways to register for the ASVAB – through a high school career guidance officer and the local military recruiter. There is no cost to take the ASVAB.


You receive a standard score on the Assembling Objects subtests. This score is derived from the total number of points you received on a scale of 30 to 70. Each correct answer is one point, incorrect answers do not receive a point, and blank answers are penalized. For that reason, it is beneficial to guess and not leave any questions blank. However, your score is impacted if you have many incorrect answers toward the end of the subtest.


You have less than one minute per question in this subtest. Your score on this section is not as important as the other subtests, so try to have a little fun with it. Prepare by doing more puzzles, playing computer games, reading maps to learn scale and visualization, and practicing sketching. These activities can help you prepare your mind to visualize the shape, direction, and scale of objects.
