The

**ASVAB**, or Armed Services Vocational Aptitude Battery is a test you will be expected to take before entering any branch of

military service in the

United States, regardless of your prior education. The

**ASVAB** is made up of the following test subjects, in the order of administration:

General Science
Arithmetic Reasoning
Word Knowledge
Paragraph Comprehension
Numerical Operations
Coding Speed
Auto & Shop Information
Mathematics Knowledge
Mechanical Comprehension
Electronics Information
**General Science** - *11 Minutes* - 25 Items

Measures knowledge of the physical and biological sciences.

**Arithmetic Reasoning** - *36 Minutes* - 30 Items

Measures ability to solve arithmetic word problems.

**Word Knowledge** - *11 Minutes* - 35 Items

Measure ability to select the correct meaning of words presented in context and identify the best synonym for a given word.

**Paragraph Comprehension** - *13 Minutes* - 15 Items

Measures ability to obtain information from written passages.

**Numerical Operations** - *3 Minutes* - 50 Items

Measures ability to perform arithmetic computations in a speeded context.

**Coding Speed** - *7 Minutes* - 84 Items

Measures ability to use a key in assigning code numbers to words in a speeded context.

**Auto & Shop Information** - *11 Minutes* - 25 Items

Measures knowledge of automobiles, tools, and shop terminology and practices.

**Mathematics Knowledge** - *24 Minutes* - 25 Items

Half of these tests are grouped around 3 academic composites:

**Academic Ability**

##### Measures potential for further formal education

*Word Knowledge and Paragraph Comprehension + Arithmetic and Mathematics Knowledge*
**Verbal Ability**

##### Measures capacity for verbal activities

*Word Knowledge + Paragraph Comprehension*
**Math Ability**

##### Measures capacity for mathematical activities

*Arithmetic Reasoning + Mathematics Knowledge*

The other half of the tests are simply for measuring how fast you can complete certain tasks, or additional knowledge one may have acquired.

All of the tests are multiple-choice, with either 4 or 5 optional answers.

Scoring on the **ASVAB** is as follows:

(2 x the number of correct answers on Word Knowledge) + (2 x the number correct on Paragraph Comprehension) + the number correct on Arithmetic Reasoning + the number correct on Mathematic Knowledge = the raw score, which is then converted into a percentile score.

On the rare occasion that you would have to study for the **ASVAB**, you only need to concentrate on Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning and Mathematics Knowledge. These are the only tests that influence the end score. All others are just for better categorization of your skills.
