As an aspiring EMT, in order to best study and get ready for the NREMT Exam, you must first know how the NREMT Exam is designed. The NREMT Exam is developed on what is called a Computer Adaptive Test (often called a C-A-T or CAT. ) This sort of exam is obviously computer based and is referred to as an “adaptive” exam based on an Item Response Theory (IRT) that rationally delivers questions dependent on the test takers response to previous questions. This is clearly much different than a “linear” exam in which questions are randomly picked from a question bank. Computer Adaptive Tests are popular in “high stakes” exams such as the NREMT for the EMT where test taker skill needs to be calculated as accurately as possible.
When creating these tests, every question is calibrated to establish what scale of difficulty it will be placed. This is accomplished by means of “pilot” questions loaded into every assessment that will not count for or against the test taker through the scoring of his or her examination. The level of difficulty associated with the question pinpoints the “level of ability” necessary to answer the question accurately. Some questions are determined to be a low level of ability while others are determined to call for a greater level of ability from the test taker.
The amount of questions that every test taker is presented with ranges when taking this form of an examination. As questions are answered properly or inaccurately, the questions presented adjust in difficulty until a specific level of expertise is proven. This is accomplished generally by starting the exam with questions slightly below the standard set for passing. As soon as a sequence of these questions are responded to appropriately, the computer will pick questions requiring an increased ability to answer correctly. If the greater part of this collection of questions are appropriately answered, the computer will yet again, select questions that require an even greater level of ability until the test taker reaches their maximum level of ability. This precisely why the NREMT Exam “feels” more difficult than other examinations and also why test takers generally feel like they did not score well at the end of the test. The correct and incorrect answers coupled with the level of difficulty of each question is located on a standard scale to determine the test takers overall ability. Once the computer determines that the test taker is either executing above or below the standard, entry-level competency, the exam will stop. The test taker that exhibits the ability to answer the bulk of the questions correctly generally finds that their test comes to an end early. This occurs when the computer is capable to see that the test taker is regularly capable of answering questions above the standard, entry-level competency. The exam will stop as soon as the computer is 95% confident that the test taker has achieved this level. Early completion of the exam can also take place if the test taker demonstrates within 95% confidence that they are not able to reach the standard, entry-level competency. The most powerful means to ensure that you fulfill the standard entry-level competency when you take this examination is to exercise good study practices and use effective NREMT exam study tools.
