The IRT model underlying ASVAB scoring is the three-parameter logistic (3PL) model. The 3PL model represents the probability that an examinee at a given level of ability will respond correctly to an individual item with given characteristics. Specifically, the item characteristics represented in the 3PL model are difficulty, discrimination (i.e., how well the item discriminates among examinees of differing levels of ability), and guessing (i.e., the likelihood that a very low ability examinee would respond correctly simply by guessing).

Soldiers and armies have been prominent in popular culture since the beginnings of recorded history. In addition to the countless images of military leaders in heroic poses from antiquity, they have been an enduring source of inspiration in war literature. Not all of this has been entirely complementary, and the military have been lampooned or ridiculed as often as they have been idolised. The classical Greek writer Aristophanes, devoted an entire comedy, Lysistrata, to a strike organised by military wives, where they withhold sex from their husbands to prevent them from going to war.


The adaptive test is exactly what it sounds like, a test that adapts to the test taker. Questions in each section range in difficulty, and based on the test taker’s answers, the question types and difficulties adjust with each answer. This type of test allows for a greater level of accuracy in evaluating a prospect’s abilities. For the most part, correct answers beget more difficult questions while wrong answers will reduce the difficulty of proceeding questions.


The Assembling Objects section of the ASVAB practice test measures your ability to determine how an object will look when its parts are put together. You will be shown an illustration of pieces and asked to choose which one, among a selection of finished diagrams, shows how they fit together. The CAT-ASVAB has 16 questions in 16 minutes, while the paper-and-pencil version has 25 questions in 15 minutes.
I purchased your AFQT Secrets file, and I just wanted to let you know that I got a 99% on my test. I just got my job of choice today of Military Intelligence Analyst, and I am now on the road to my future career in the CIA or NSA. I just want to thank you again, and hope you have continued success in your ventures. Sincerely, Paul L. U.S. Army (Intel Analyst
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 ASVAB also known as the Armed Services Vocational Aptitude Battery is a test that measures your aptitude which is how well you do something.  A common mistake by most people is thinking that it is a measure of you IQ. Many people either forget this or don’t know this and they get worked up about the exam.  Saying that, it is also important to take a ASVAB sample test to insure you know what type of questions will be asked.    Another thing to keep in mind is every person in the armed forces has to take the exam and you are not being called out to take it. 
The underlying model used for the ASVAB is a three-parameter logistic (3PL) model. This model represents the probability that an examinee at a given level of ability will respond correctly to an individual item with given characteristics. The characteristics used are difficulty, discrimination and guessing (this refers to the likelihood that a very low ability examinee would respond correctly simply by guessing).
This course is designed to help you dust the cobwebs off information you may have learned long ago or boost your scores if you have already taken the test (or a sample test administered by a recruiter) and did not meet the score you needed for the occupation you desire. This review is particularly helpful if you have been out of school for some time, did not graduate a standard high school program, or either did not take or performed poorly in classes related certain subject areas (e.g. shop or automotive classes). Within each subject area, the lessons build on one another, so we will help you progress in a logical manner in bite-sized, 10-minute-or-less chunks. Skip to the lessons that you know you need to focus on, and even jump to specific portions of the videos using the video tags. Use the quizzes, chapter tests, and course exam to see how you're doing and refocus your studies as necessary.
The SAT requires training of the mind. More specifically it requires one to be able to pick up on context clues, make valid assumptions, and express concrete facts. This is why millions of students study intensely before they jump right into the test. Imagine if another area was added onto that same test. The person studying for that test would then need to study even harder. That is the logic that should be put forth when preparing for the ASVAB. It requires that a person expresses the previously mentioned skills while adding the verbal/physical aspects. The question becomes “How does one prepare themselves for this rigorous test?”

There are nine sections on the exam: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Automotive and Shop Information, Mechanical Comprehension, Assembling Objects, and Verbal Expression. The time limits for each section range from 10 – 36 minutes; the entire exam takes three hours.
First, the ASVAB measures your accumulated knowledge in different areas. So if you are currently in school, stay focused and study hard. Your overall knowledge gained in school will most likely be reflected in your ASVAB score. Second, though accumulated knowledge is important, you may be able to raise your score by preparing specifically for the ASVAB, especially in areas where you are weak. Various study guides are available for this purpose (listed left).

The meaning of military tactics has changed over time; from the deployment and manoeuvring of entire land armies on the fields of ancient battles, and galley fleets; to modern use of small unit ambushes, encirclements, bombardment attacks, frontal assaults, air assaults, hit-and-run tactics used mainly by guerrilla forces, and, in some cases, suicide attacks on land and at sea. Evolution of aerial warfare introduced its own air combat tactics. Often, military deception, in the form of military camouflage or misdirection using decoys, is used to confuse the enemy as a tactic.
Every single individual that goes through the enlistment process should excel both mentally and physically. That is the number one principle that has consistently inspired this nation to serve these brave and honorable individuals with unwavering efforts. Those efforts officially came to the forefront when the country as a whole decided to correct perhaps the most significant enlistment related problem (passing the Armed Services Vocational Aptitude Battery test). Countless hours of hard work and dedication are currently reflected by the top-of-the-line ASVAB practice tests that this nation offers.
