There is another ASVAB score that's equally important, if not more so, because it is the score that determines if a person is eligible for military service. It's the Armed Forces Qualification Test score, or AFQT score. This score is calculated from only four of the nine Standard Scores on the ASVAB - Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). First, the WK and PC scores are added together, then the sum is doubled. This is known as the Verbal Expression (VE) score. The VE, MK, and AR scores are then added together, and the sum is the AFQT. This score is a straight percentile measure, expressed as a number from 1-99. The number is the percentage of people who scored lower than the test taker. For example, if a person receives an AFQT score of 63, that means that he did better on the test than 63% of the people who have taken it.
The ASVAB is a population-referenced exam, which means that the score you receive for the ASVAB is not an exact measure of how you scored on the test, but rather how you scored in relation to a national control group who took the test in 1997. Standard Scores are used on the ASVAB: in each subtest, about 50% of the population received a Standard Score of 50, while only 16% scored over 60. You will receive an estimated score after taking the paper test and official scores later through your recruiter, usually within days. You will immediately receive your scores upon completing the computer test.
Again, we must stress that there is no passing or failing score on the exam. The test is a measure of aptitude and provides percentile rankings to indicate your performance compared to other test takers. However, different branches of the military do have minimum score requirements for enlistment. This means that it’s important to make sure you’re prepared for test day, and that’s where a practice test will prove valuable.
The P&P-ASVAB gives you a set number of questions to answer and a set time limit. If you finish a section before your time runs out, you may go back and review your answers and change them if you want to. It’s better to answer all of the questions on the P&P-ASVAB – there is no penalty for guessing because only correct answers are added to make up your final score.
The paper-and-pencil version of the test administered at a Mobile Examination Test (MET) site usually takes 3–4 hours. The time needed to take the CAT-ASVAB test can vary. The test is adaptive. If the candidates answer a question correctly, they are given one of increasing difficulty. If the candidates miss a question, they are subsequently given an easier item. This pattern continues until the test is finished. Because of its adaptive nature, the CAT-ASVAB test generally takes about half the time of the paper-and-pencil version.
The General Science section of the test covers earth, space, and physical and life sciences. Because science is such a vast and dynamic topic, focus your study on basic principles. This gives you a good foundation to work through any question that is asked of you. Typical questions may include: “Why is air less dense than water?” or “How do you convert Celsius temperature to Fahrenheit?” The CAT-ASVAB test asks 16 questions in 8 minutes, while the pencil-and-paper version asks 25 questions in 11 minutes.
There have been attempts to produce a military strength index: this is an example taken from a Credit Suisse report in September 2015. The factors under consideration for that military strength indicator and their total weights were: number of active personnel in the army (5%), tanks (10%), attack helicopters (15%), aircraft (20%), aircraft carriers (25%), and submarines (25%). It was practically impossible to make an estimation of the actual training of the armed forces.  These were the results:
As in most militaries, members of the U.S. Armed Forces hold a rank, either that of officer, warrant officer or enlisted, to determine seniority and eligibility for promotion. Those who have served are known as veterans. Rank names may be different between services, but they are matched to each other by their corresponding paygrade. Officers who hold the same rank or paygrade are distinguished by their date of rank to determine seniority, while officers who serve in certain positions of office of importance set by law, outrank all other officers in active duty of the same rank and paygrade, regardless of their date of rank. In 2012, it was reported that only one in four persons in the United States of the proper age meet the moral, academic and physical standards for military service.
 See two documents: Sims, W.H. and Truss, A.R., A Reexamination of the Normalization of Armed Services Vocational Aptitude Battery (ASVAB) Forms 6, 7, 6E, and 7E (Alexandria, VA: Center for Naval Analyses, September 1980); and Laurence, J.H. and Ramsberger, P.F., Low-Aptitude Men in the Military: Who Profits, Who Pays? (New York: Praeger, 1991).
The test must be completed if you wish to serve in the Army, Navy, Marines, Air Force, or Coast Guard. The test can also be taken as a career-exploration tool if you are a high school sophomore, junior, or senior. It takes approximately three hours to complete. If you take the computerized version of the test, results are given immediately. If you complete a paper and pencil test, you’ll get results within two weeks.
Under the Student Loan Repayment Program, when you enlist the Army will pay back up to $65,000 in qualified education loans (up to $20,000 for reservists), the Navy up to $65,000 and the Air Force up to $10,000. Each year 15% of the loan balance or $500, whichever is greater, will be repaid by SLRP. There may also be annual and cumulative caps on the amount repaid. Participants must score 50 or higher on the Armed Forces Qualifications Test (AFQT). SLRP must be requested at the time of enlistment or reenlistment. Qualified education loans include federal education loans such as the Perkins, Stafford, PLUS, or Consolidation loans, but not private alternative loans. Defaulted loans are not eligible. Payments made under the SLRP are considered taxable income.
In order to perform well on the ASVAB, you should take a practice test to get an idea of what you’ll encounter on the actual test. Also, completing a practice test will help you to feel more at ease on test day. Reading the test instructions and focusing your full attention on each question are both important steps to take. As you work through the test, avoid spending too much time on a single question. The test has a time limit and you don’t want to fall into the trap of running out of time before you arrive at the end of the test. Taking the time to provide thoughtful answers to test questions allows you to offer a clear picture of your skills and capabilities. Earning a high score on the ASVAB may give you more options when it comes to choosing a specialty.
All of the branches work together during operations and joint missions in Unified Combatant Commands, under the authority of the Secretary of Defense with the typical exception of the Coast Guard. Each of the Unified Combatant Commands is headed by a Combatant Commander, a senior commissioned officer who exercises supreme command authority per 10 U.S.C. § 164 over all of the forces, regardless of branch, within his geographical or functional command. By statute, the chain of command flows from the President to the Secretary of Defense to each of the Combatant Commanders. In practice, the Chairman of the Joint Chiefs of Staff often acts as an intermediary between the Secretary of Defense and the Combatant Commanders.
The Student ASVAB is the most flexible of the exams. It is typically provided to high school students to help them assess their skills, job prospects, potential military positions, or college majors. The ASVAB for students is essentially the same as the MET ASVAB exam, only students are not necessarily testing for positions within the military. The students’ school counselors examine their scores and help them decide on what to do after graduating from high school. This test is still an important component of a student’s education because it can help them identify their strengths and weaknesses and help set them on the right track for their future career goals.
