    Everything You Need To Know About The ABIM Longitudinal Assessment

    Recently, the American Board of Internal Medicine announced its commitment to evolving into a longitudinal assessment for its Maintenance of Certification (MOC) program. This new self-paced Longitudinal Knowledge Assessment (LKA) will be available in 2022.

    About ABIM's Longitudinal Assessment 

    What Is The Longitudinal Knowledge Assessment? 

    Physicians told the ABIM they need a more flexible learning experience that they can do on nights and weekends (without all the high security at test centers!) and wanted questions that provide feedback about why the right answer is right, and also why the wrong answer is wrong.

    Instead of studying everything you need for the traditional 10-year MOC exam all at once, this new way of maintaining certification will help you assess your medical knowledge in chunks.

    This new ABIM longitudinal exam format will allow you to log on from anywhere, and answer questions at your own pace—using the same resources you use while treating patients. You just have to answer the required number of questions in a set amount of time. 

    The ABIM Longitudinal Exam includes 120 questions offered per year for 5 years. You can skip 100 questions over the 5-year period.

    ABIM Longitudinal Exam vs Knowledge Check-In

    This new ABIM MOC assessment option will replace the 2-year Knowledge Check-In Exam that was rolled out in 2018, but you will still have the traditional 10-year MOC exam as an option. 

    This kind of exam supports the science-backed information about how adults learn best: frequent information with quick feedback, repetition of material, and identifying gaps in knowledge.

    What Will The Longitudinal Assessment Be Like?

    • The exam is more flexible. You'll have a set amount of time to answer a set amount of questions—you are in charge of your own exam schedule from there. You can answer 1 question per day, or tackle several questions back-to-back. 
    • There will be more learning opportunities. With each question, you get immediate feedback about the correctness of your answer, and opportunities to learn why your answer was correct or incorrect.
    • An open book testing experience. If the ABIM follows suit with other medical specialties, this exam type is likely to be open book, meaning you can use any resources during the exam that you use when treating patients. 
    • There will be an annual cost. While the ABIM is still figuring out how to structure the cost for this new kind of exam, they don’t expect that total cost to be higher than the 10-year exam.

    ABIM Knowledge Assessment Questions

    The ABIM Longitudinal Knowledge Assessment uses the same MOC blueprint as the 10-year exam. The 600 questions presented to you quarterly over 5 years can be pulled from any of the content areas on the blueprint.

    The ABIM Longitudinal Exam will present 600 questions for you to answer over the 5 years—120 questions per quarter. You can skip up to 100 questions throughout the 5-year testing time. 

    What's The Longitudinal Assessment Passing Score? 

    Since you get immediate feedback about the correctness of your answers as you go, you know how you're doing and where you stand throughout the LKA. At the end of the 5-year cycle, the ABIM will let you know if you met the passing score.

    If you are successful, you'll be able to continue with the LKA, if not, you still have the opportunity to take the traditional 10-year MOC exam to maintain certification.
