How Do I Calculate My ASVAB Score?

The Armed Services Vocational Aptitude Battery (ASVAB) is a crucial examination for anyone considering a career in the U.S. military. It is a series of tests that determine your qualifications for various military occupations and special programs. In this blog post, we’ll guide you on how to calculate your ASVAB score and help you understand what it means for your military career.

Understanding the ASVAB

Before we delve into the specifics of calculating your ASVAB score, let’s take a moment to understand what the ASVAB is and how it’s structured. ASVAB stands for Armed Services Vocational Aptitude Battery. This multiple-choice test is used by all branches of the U.S. military to determine eligibility for enlistment and to assign recruits into career paths best suited to their skills and abilities.

The ASVAB contains either nine or ten sections (subtests), depending on whether you take the computerized version (CAT-ASVAB) or the pen and paper version. Here’s a brief description of each section:

General Science (GS): This section tests your knowledge in physical and biological sciences. It includes topics such as biology, chemistry, earth science, and physics.

Arithmetic Reasoning (AR): Here, you’ll be tested on basic arithmetic problems. These problems often come in the form of word problems that require problem-solving skills.

Word Knowledge (WK): This section evaluates your vocabulary. You’ll need to identify synonyms, antonyms, and correct meanings of words.

Paragraph Comprehension (PC): This subtest measures your reading comprehension skills. You’ll be asked to read a passage and then answer questions based on the information provided in the text.

Mathematics Knowledge (MK): This section tests more advanced mathematical knowledge, including concepts from algebra and geometry.

Electronics Information (EI): This subtest gauges your understanding of electrical equipment and systems, including basic electrical principles and electronics.

Auto and Shop Information (AS): Here, your knowledge about automobile maintenance and repair, as well as woodworking and metalworking, is assessed.

Mechanical Comprehension (MC): This section tests your understanding of mechanical and physical principles.

Assembling Objects (AO): This subtest is unique to the ASVAB and measures your spatial perception and ability to understand diagrams.

Each of these subtests covers a specific area and helps the military assess whether you possess the skills and knowledge necessary for certain military occupations. Your scores in these areas will not only determine your eligibility for service but also provide a path to military careers that align best with your strengths.

Raw Scores vs Standard Scores

When it comes to ASVAB scores, it’s crucial to understand the difference between raw scores and standard scores. Each of these has a distinct purpose and method of calculation.

Raw Scores

Your raw score is the most straightforward calculation. It’s simply the total number of questions you answered correctly on the ASVAB. For example, if there are 60 questions on a particular section and you answer 45 correctly, your raw score for that section is 45.

However, raw scores are limited in their usefulness because they do not take into account the difficulty of the questions you answered or compare your performance with other test-takers. Therefore, raw scores are not often used in determining your eligibility for military service or for particular military occupations.

Standard Scores

Standard scores, on the other hand, offer a more nuanced and meaningful picture of your performance. These scores compare your raw scores to the performance of a reference group, typically a large, nationally representative sample of test-takers. In this way, your standard score shows how you performed relative to others who took the ASVAB.

The standard score calculation involves a statistical process called “scaling.” The raw score is transformed using a formula that adjusts for differences in the difficulty of the test questions. The resulting standard scores typically have a mean of 50 and a standard deviation of 10. This means a standard score of 50 represents average performance on the ASVAB, while each increment of 10 from 50 represents an additional standard deviation from the mean. For example, a standard score of 60 indicates performance one standard deviation above the average, putting you in the 84th percentile.

The military uses your standard scores from the nine or ten sections of the ASVAB to calculate two crucial metrics: your Armed Forces Qualification Test (AFQT) score, which determines your eligibility for enlistment, and your line scores, which determine your eligibility for specific military occupations.

Understanding the difference between raw scores and standard scores is essential to understanding your ASVAB results. While raw scores give a snapshot of how many questions you answered correctly, standard scores provide a more meaningful and standardized measurement of your performance in relation to other test-takers.

AFQT Scores

The Armed Forces Qualification Test (AFQT) score is perhaps the most crucial score derived from your ASVAB results. This score is used by all branches of the U.S. military to determine eligibility for enlistment. It represents a percentile ranking that shows how your score compares to that of other 18 to 23-year-olds in the U.S.

The AFQT score is calculated from your raw scores on four sections of the ASVAB: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). Here is a step-by-step guide on how to calculate your AFQT score:

Mathematical Knowledge score (M): Begin by adding together your raw scores from the AR and MK sections. The result is your Mathematical Knowledge score (M). For example, if your AR score is 55 and your MK score is 60, your M score would be 115.

Verbal Expression score (VE): Next, add together your raw scores from the WK and PC sections. This result is your Verbal Expression score (VE). For instance, if your WK score is 35 and your PC score is 40, your VE score would be 75.

Calculating the AFQT score: Now, double your VE score and then add the M score. This gives you your AFQT score. Using the previous examples, you would multiply the VE score of 75 by 2 to get 150, and then add the M score of 115. This would result in an AFQT score of 265.

AFQT Percentile Score: The AFQT score is then converted into a percentile score, which ranges from 1 to 99. This score indicates the percentage of individuals in the reference group who scored at or below your score. For instance, if your AFQT percentile score is 65, that means you scored as well as or better than 65% of the nationally representative sample of 18 to 23-year-olds. The conversion of the AFQT score to a percentile score is a complex process involving statistical scaling. You won’t be able to calculate this conversion yourself; your official AFQT percentile score will be provided to you after you take the ASVAB.

It’s important to understand that different branches of the military have different minimum AFQT score requirements for enlistment. Furthermore, higher AFQT scores often grant access to a wider range of jobs within the military. Therefore, aiming for a high AFQT score is in your best interest when preparing for the ASVAB.

Calculating Line Scores

In addition to the AFQT score, the military also uses “line scores” derived from various combinations of the ASVAB subtests. These scores are crucial in determining your qualifications for specific military occupations. Each branch of the U.S. military has its own unique formula for calculating line scores and different line score requirements for each job.

What are Line Scores?

Line scores are composite scores created from individual ASVAB subtest scores. Each line score represents a different aptitude or skill set and corresponds to certain military jobs or Military Occupational Specialties (MOS).

For example, an Army Clerical (CL) line score is determined by the sum of the Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR), and Mathematics Knowledge (MK) subtests. This score indicates a recruit’s aptitude for clerical or administrative roles.

Calculating Line Scores

The exact formula for calculating line scores varies by military branch, as each branch values certain skills and aptitudes differently based on its specific needs and roles. For example, the formula for a General Technical (GT) line score (often used for jobs that require general cognitive and reasoning abilities) is computed differently across services:

• In the Army and Marines, the GT score is the sum of the Verbal Expression (VE) and Arithmetic Reasoning (AR) scores.

• In the Navy, it’s the sum of the VE, AR, and Mechanical Comprehension (MC) scores.

• In the Air Force, it’s the sum of the VE, AR, and Mathematics Knowledge (MK) scores.

Unfortunately, the raw line scores aren’t very meaningful on their own, just like the raw scores from individual subtests. To standardize them, the military converts raw line scores to scaled scores using a statistical process that adjusts for variations in the difficulty level of the subtests. This process is similar to how the AFQT score is calculated and scaled.

Importance of Line Scores

The line scores play a significant role in the military enlistment process. They help determine the job roles for which you are best suited, and different jobs require different minimum line scores. For instance, an Army Human Intelligence Collector (MOS 35M) requires a Skilled Technical (ST) line score of 101, while an Army Cryptologic Cyberspace Intelligence Collector/Analyst (MOS 35Q) requires a General Technical (GT) score of 105.

Understanding how line scores work and what they mean for your potential military career is essential when preparing for the ASVAB. If you have a specific military job in mind, find out which line scores are relevant to that job and focus your study efforts on the subtests that contribute to those line scores.

Interpreting Your ASVAB Score

Understanding how to calculate your ASVAB scores is just the beginning; interpreting what these scores mean for your military career is equally essential. The AFQT score and the line scores play significant roles in determining your eligibility for military service and the range of job opportunities available to you.

Interpreting Your AFQT Score

Your AFQT score, expressed as a percentile, represents how well you performed compared to a nationally representative sample of 18 to 23-year-olds. A higher AFQT score signifies a better performance.

Generally, an AFQT score of 50 or above is considered high and opens up a broader range of opportunities in the military. However, the minimum AFQT score required for enlistment varies among the different branches of the U.S. military and is subject to change:

• Army: Minimum AFQT score of 31

• Navy: Minimum AFQT score of 35

• Air Force: Minimum AFQT score of 36

• Marines: Minimum AFQT score of 31

• Coast Guard: Minimum AFQT score of 40

Interpreting Your Line Scores

Line scores, on the other hand, determine your eligibility for specific military occupations. Each job within the military, known as a Military Occupational Specialty (MOS) in the Army and Marines, or a rating in the Navy, requires a certain minimum line score.

For example, suppose you are interested in an intelligence job in the Army. In that case, you’ll want to score highly on the line score associated with that job, typically the General Technical (GT) or Skilled Technical (ST) score. The higher your line score in the relevant category, the better your chances are of qualifying for the job.

The Importance of Understanding Your ASVAB Scores

Understanding and interpreting your ASVAB scores allows you to gauge your eligibility for military service and specific jobs. Moreover, it provides insights into your strengths and areas for improvement. This information can guide your study and preparation if you plan to retake the ASVAB to improve your scores.

Remember, while getting a high AFQT score is crucial, it’s not the only thing that matters. Your line scores are equally significant, especially if you have a specific military job in mind. The key is to focus on both – achieving a strong overall performance on the ASVAB while also targeting the specific areas that matter most for your desired career path.

Preparing for the ASVAB

Understanding how your ASVAB scores are calculated is an essential step towards effective test preparation. By concentrating on the subtests that contribute to both the AFQT score and the line scores related to your desired military job, you can maximize your study efforts and increase your chances of success.

Understanding the Test

Begin your preparation by familiarizing yourself with the ASVAB’s structure and the types of questions asked in each subtest. This knowledge will not only help you understand what to expect on test day, but it will also assist you in identifying which areas require more focus and practice.

Remember, the AFQT score—which determines your eligibility for military enlistment—is calculated based on four sections: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). Therefore, these areas should be a primary focus of your study.

Study Resources

Numerous resources are available to help you prepare for the ASVAB:

• ASVAB Study Guides: Comprehensive guides, available in bookstores and online, provide an in-depth review of the material covered in each subtest, test-taking strategies, and practice questions.
