Your application must be received before 5:00 pm Mountain time on the application due date. Once your application is approved, you are directed back to your account to pay the $710 testing fee and schedule your exam date and location. The exam is offered at college campuses and Prometric testing facilities located nationwide.<\/p>\n<h3><span id=\"Withdrawal_or_Date_Change\" class=\"m-toc-anchor\"><\/span>Withdrawal or Date Change<\/h3>\n<p>You can withdraw or reschedule your appointment through your Prometric account, but note that any changes must be made BEFORE the application deadline for your exam date. Partial refunds are given for withdrawal.<\/p>\n<p>Once the deadline passes, you cannot make changes to your appointment and will not be issued a refund.<\/p>\n<h3><span id=\"Scholarships\" class=\"m-toc-anchor\"><\/span>Scholarships<\/h3>\n<p>NBCE offers four competitive scholarships, with winners receiving up to a $2,500 award. The National Chiropractic Mutual Insurance Company (NCMIC) Board provides a quarterly scholarship to 25 students, who are randomly drawn from exam applicants. The winners of this scholarship are awarded $1,000 to assist with board exam costs. Students can enter once quarterly but can only win once.<\/p>\n<h2 class=\"pt-page\"><span id=\"How_the_Exam_is_Scored\" class=\"m-toc-anchor\"><\/span>How the Exam is Scored<\/h2>\n<p>NBCE evaluates the number of questions you answered correctly, the questions\u2019 difficulty, and the exam&#8217;s relative difficulty. Through statistical calculations, your exam is equated and then translated into a scaled score from 125 to 800.<\/p>\n<p>In a nutshell, the scaled score results from converting your raw score onto a standard scale which accounts for the variable difficulty level of different test forms. To pass Part I, you must achieve a scaled score of 375. There is not a direct relationship between the number of correctly answered items and the final scaled score.<\/p>\n<p>Your exam results are posted to your NBCE account approximately four weeks after taking the exam. An official transcript, which is a record of your most recent passing scores, bears the NBCE seal and is sent to licensing authorities at your request. Official transcripts will only be sent if you meet the passing score of 375, unless you expressly authorize the release of a non-passing transcript.<\/p>\n<p>To have an official transcript sent, you must submit a transcript request through your NBCE account. Your first transcript request is free. Additional official transcripts are $25 per state, and other processing fees may apply. Most states do not require a transcript until you have completed all four parts of the NBCE exam.<\/p>\n<h2 class=\"pt-page\"><span id=\"Retaking_the_Exam\" class=\"m-toc-anchor\"><\/span>Retaking the Exam<\/h2>\n<p>Each domain is scored individually, and a separate analysis is provided for each failed exam so you can prepare to retake the exam for that domain. You are eligible to retake each domain as many times as needed to pass. However, if you passed four or more domains, you are eligible to retake only the domains you failed.<\/p>\n<p>If you need to retake the entire Part I exam, the fee is $710.<\/p>\n\n\t\t\t<div class=\"sg-box\">\n\t\t\t\t<div class=\"sg-box-text\">\n\t\t\t\t\t<p class=\"sg-box-title\">Check Out Mometrix's NBCE Part I Flashcards<\/p>\n\t\t\t\t\t<p>Get complex  subjects broken down into easily understandable concepts<\/p>\n\t\t\t\t\t<a class=\"sg-box-button blue-button\" href=\"https:\/\/www.flashcardsecrets.com\/nbce\/\" target=\"_blank\" rel=\"noopener\">Get Your Flashcards<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t<a href=\"https:\/\/www.flashcardsecrets.com\/nbce\/\">\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"238\" height=\"184\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/11\/nbcepartiflash.jpg\" alt=\" Flashcards\">\n\t\t\t\t<\/a>\n\t\t\t<\/div>\n<h2 class=\"pt-page\"><span id=\"How_to_Study_for_Part_I_of_the_NBCE_Exam\" class=\"m-toc-anchor\"><\/span>How to Study for Part I of the NBCE Exam<\/h2>\n<h3><span id=\"How_to_Study_Effectively\" class=\"m-toc-anchor\"><\/span>How to Study Effectively<\/h3>\n<p>Your success on NBCE test day depends not only on how many hours you put into preparing but also on whether you prepared the right way. It\u2019s 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 NBCE practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a free NBCE exam practice test, pay special attention to these three groups of questions:<\/p>\n<ul>\n<li>The questions you got wrong<\/li>\n<li>The ones you had to guess on, even if you guessed right<\/li>\n<li>The ones you found difficult or slow to work through<\/li>\n<\/ul>\n<p>This will show you exactly what your weak areas are and where you need to devote more study time. Ask yourself why each of these questions gave you trouble. Was it because you didn\u2019t understand the material? Was it because you didn\u2019t remember the vocabulary? Do you need more repetitions on this type of question to build speed and confidence? Dig into those questions and figure out how you can strengthen your weak areas as you go back to review the material.<\/p>\n<h3><span id=\"Answer_Explanations\" class=\"m-toc-anchor\"><\/span>Answer Explanations<\/h3>\n<p>Additionally, many NBCE 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\u2019s broader context. Even if the explanation makes sense, go back and investigate every concept related to the question until you\u2019re positive you have a thorough understanding.<\/p>\n<h3><span id=\"Comprehend_Each_Topic\" class=\"m-toc-anchor\"><\/span>Comprehend Each Topic<\/h3>\n<p>As you go along, keep in mind that the NBCE Part I practice test is just that: practice. Memorizing these questions and answers will not be very helpful on the actual test because it is unlikely to have any of the same exact questions. If you only know the right answers to the sample questions, you won\u2019t be prepared for the real thing. Study the concepts until you understand them fully, and then you\u2019ll be able to answer any question that shows up on the test.<\/p>\n<h3><span id=\"Strategy_for_NBCE_Practice\" class=\"m-toc-anchor\"><\/span>Strategy for NBCE Practice<\/h3>\n<p>When you\u2019re ready to start taking practice tests, follow this strategy:<\/p>\n<ul>\n<li style=\"margin-bottom: 10px\"><strong>Remove Limitations.<\/strong> Take the first test with no time constraints and with your notes and NBCE study guide handy. Take your time and focus on applying the strategies you\u2019ve learned.<\/li>\n<li style=\"margin-bottom: 10px\"><strong>Time Yourself.<\/strong> Take the second practice test \u201copen book\u201d as well, but set a timer and practice pacing yourself to finish in time.<\/li>\n<li style=\"margin-bottom: 10px\"><strong>Simulate Test Day.<\/strong> Take any other practice tests as if it were test day. Set a timer and put away your study materials. Sit at a table or desk in a quiet room, imagine yourself at the testing center, and answer questions as quickly and accurately as possible.<\/li>\n<li><strong>Keep Practicing.<\/strong> Keep taking practice tests on a regular basis until you run out of practice tests or it\u2019s time for the actual test. Your mind will be ready for the schedule and stress of test day, and you\u2019ll be able to focus on recalling the material you\u2019ve learned.<\/li>\n<\/ul>\n<h2 class=\"pt-page\"><span id=\"FAQs\" class=\"m-toc-anchor\"><\/span>FAQs<\/h2>\n<div class=\"faq-list\">\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">How many questions are on the exam?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>There are 300 questions total on Part I of the NBCE (each domain contains 50 questions).<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">How long is the exam?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>Part I of the NBCE is timed at 4 hours and 20 minutes, which does not include the optional 15-minute breaks between sessions.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">What is a passing score?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>A passing score for Part I of the NBCE is a scaled score of 375.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"qa_wrap\">\n<div class=\"q_item text_bold\">\n<h4 class=\"letter\">Q<\/h4>\n<p style=\"line-height: unset;\">How much does the exam cost?<\/p>\n<\/p><\/div>\n<div class=\"a_item\">\n<h4 class=\"letter text_bold\">A<\/h4>\n<p>Part I of the NBCE costs $710.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n\n<p><div itemscope=\"\" itemprop=\"author\" itemtype=\"http:\/\/schema.org\/Person\" class=\"author-bio\"><img loading=\"lazy\" decoding=\"async\" itemprop=\"image\" class=\"author-image\" height=\"127\" width=\"127\" alt=\"Headshot of Mometrix associate Peter Rench.\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2024\/01\/Peter-Rench-scaled.webp\"><div class=\"author-text\"><p class=\"author-name\">By <span itemprop=\"name\">Peter Rench<\/span><\/p><div class=\"author-desc\"><p>Peter Rench joined Mometrix in 2009 and serves as Vice President of Product Development, responsible for overseeing all new product development and quality improvements.
