The Paragraph Comprehension section of the test measures your ability to read a passage and interpret the information contained within it. You may read a selection and be asked to interpret the author’s purpose, or what a particular word in the passage means, based on the context of the sentence where it appears. To help you better prepare for the exam, the Paragraph Comprehension section of the ASVAB practice test has passages of similar length and style to those on the actual ASVAB test. The CAT-ASVAB test has 11 questions in 22 minutes; the paper-and-pencil version has 15 questions in 13 minutes.
The scores from the Word Knowledge, Arithmetic Reasoning, Mathematics Knowledge, and Paragraph Comprehension are combined together and known as the Armed Forces Qualification Test (AFQT). Your AFQT scores represent a percentile between 1 and 99 and measure your ranking compared to scores from other 18 to 23 year olds. If you score a 70 on your AFQT, this implies that you scored better than 70% of test takers. Your scores on the other six ASVAB tests will help identify which jobs may be appropriate for you in the military.
After adding so much information to the aptitude test, there was a bit of difficulty interpreting the test results. In addition to that, a vast majority of test takers were deemed as being under qualified based on their test results. This is why the percentile change was made. It ensured that a 50% actually correlated with a person doing better than 50% of the test takers. Those revisions have worked hand-in-hand with the preparation of the armed forces.
