The CAT-ASVAB is an adaptive test which means the test adapts to the ability of the test-taker. It is possible to administer a shorter test this way than with the pencil and paper test. When you complete a subsection of the test, you can then move onto the next section of the test without having to wait for an administrator. Subsections are still timed however and on average it takes about 1 ½ hours to complete the computer ASVAB.

The AFQT score is a percentile score. What does that mean? In 1997, a study, known as the "Profile of American Youth," was conducted by the Department of Defense in cooperation with the Department of Labor. DOD administered the ASVAB to around 12,000 individuals, ranging in age from 16 to 23. Your AFQT score is a comparison of how well you scored on the four subtests, compared to those who took the ASVAB as part of the 1997 survey. In other words, if you have an AFQT score of 70, that means you scored as well or better than 70 percent of those 12,000 folks.

During World War I, the need to break the deadlock of trench warfare saw the rapid development of many new technologies, particularly tanks. Military aviation was extensively used, and bombers became decisive in many battles of World War II, which marked the most frantic period of weapons development in history. Many new designs, and concepts were used in combat, and all existing technologies of warfare were improved between 1939 and 1945.
A graphic view of the increasing trend in AFQT performance of accessions from FY 1981 through FY 1992 is provided in Figure 2.8. The more significant gains were in Categories I to IIIA, where the percentages increased from 47 percent in FY 1981 to 75 percent in FY 1992. Conversely, there has been a steady decline in the percentage of Category IIIB accessions. Most dramatic has been the decrease in accessions who score in Category IV—from 33 percent in FY 1979 to one percent or less since FY 1991. There has been a gradual decline in the percentage of accessions in Categories I to IIIA in the last seven years, from 75 to 65 percent.
Your success on ASVAB test day depends not only on how many hours you put into preparing, but also on whether you prepared the right way. It’s good to check along the way to see whether your studying is paying off. One of the most effective ways to do this is by taking ASVAB practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a ASVAB practice test, pay special attention to these three groups of questions:

Since 1976, the multiple-choice ASVAB has been used for initial aptitude screening as well as MOS classification. The exam has changed since its inception. While some parts have remained, such as arithmetic reasoning and word knowledge, others like tool knowledge have been removed in favor of questions related to assembling objects. After nearly 20 years of research and development, a computer-adaptive version of the exam was implemented in 1996. The CAT-ASVAB is the first large-scale adaptive battery test to be administered in high-stakes environments like a Military Entrance Processing Station. The paper and pencil, or P&P version is still used at a variety of other military testing sites.
The military organization is characterized by a strict hierarchy divided by military rank, with ranks normally grouped (in descending order of authority) as officers (e.g. Colonel), non-commissioned officers (e.g. Sergeant), and personnel at the lowest rank (e.g. Private Soldier). While senior officers make strategic decisions, subordinated military personnel (soldiers, sailors, marines, or airmen) fulfil them. Although rank titles vary by military branch and country, the rank hierarchy is common to all state armed forces worldwide.
Taking the PiCAT exam may, depending on circumstances including scores and other factors, may relieve a new recruit of having to take the ASVAB in a proctored setting. In the past, recruits who were preparing to enter military service at Military Entrance Processing Station would take the ASVAB in a group setting; PiCAT can help new recruits avoid having to retake the test. PiCAT test performance and other factors will determine whether or not the ASVAB has to be taken at MEPS.
Again, would you rather go into the ASVAB unsure of what to expect and not knowing if you studied the right things or would you prefer to have taken similar tests covering content commonly tested for on the real thing? Taking practice tests is a great way to build your knowledge, your confidence and your ASVAB familiarity so that you feel relaxed and confident on test day.
The projected active duty end strength in the armed forces for fiscal year 2017 was 1,281,900 servicemembers,[6] with an additional 801,200 people in the seven reserve components.[6] It is an all-volunteer military, but conscription through the Selective Service System can be enacted at the President's request and Congress' approval. All males ages 18 through 25 who are living in the United States are required to register with the Selective Service for a potential future draft.
The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It is often offered to American high school students when they are in the 10th, 11th and 12th grade, though anyone eligible for enlistment may take it.[2]
The ASVAB Career Exploration Program provides tools developed by the Department of Defense (DoD) to help high school and post-secondary students across the nation learn more about career exploration and planning. Since the mid-1990’s, the ASVAB Career Exploration Program has provided high quality, cost-free career exploration and planning materials and services annually to approximately 14,000 of the nation’s high schools. You can prepare by taking ASVAB Practice Tests – many of which are available online.

Additionally, many ASVAB practice tests have a section explaining the answer choices. It can be tempting to read the explanation and think that you now have a good understanding of the concept. However, an explanation likely only covers part of the question’s broader context. Even if the explanation makes sense, go back and investigate every concept related to the question until you’re positive you have a thorough understanding.

Another big advantage of practice tests is that they are fun. It’s fun to challenge yourself and see what you know. Instead of wondering if you are studying the right things or just wasting your valuable time, good practice tests can help you find out what you need to know while injecting your study time with excitement and competition as you try to outdo yourself each time you take a test.
Anyone who is planning to enlist in the United States Armed Forces should be familiar with the military’s standards and screening processes. An important part of this screening process is the Armed Forces Qualification Test (AFQT), which is a subsection of the Armed Services Vocational Aptitude Battery (ASVAB). This standardized assessment measures a candidate’s skills in the areas of paragraph comprehension, word knowledge, arithmetic reasoning, and mathematics knowledge.

After adopting the test in 1976 the test became a way of indicating whether or not an individual was 100% qualified to serve. As previously mentioned this aptitude test has a colorful history. That is because it underwent a dramatic change in 2002 and another dramatic change in 2004. The change that occurred in 2002 expanded the categories of the test and the overall difficulty. This can be seen by the addition of all of the diverse categories below:
