The United States Medical Licensure Examination Step 2 CK (Clinical Knowledge) is the second step in the bid to become licensed to practice medicine in the United States. In contrast to Step 1, which focuses on your knowledge of foundational biosciences, Step 2 CK was created to test if you possess sufficient medical knowledge and skills as well as an understanding of clinical sciences and practices. The goal of the exam is not to see if you can memorise vast information about the body and pathologies, but if you understand them in the practical context, you are also tested on your basic patient-centred skills.
The Step 2 CK exam is jointly administered by the National Board of Medical Examiners and the Federation of State Medical Boards. It specifically assesses your capacity to make sound clinical decisions and to integrate your multi-disciplinary knowledge, reflecting real-world patient care scenarios. The exam is usually taken during the third or fourth year of medical school by U.S medical students. It is designed to ensure that all who take it possess the clinical competency required to practice medicine in the U.S healthcare system safely.
Step 2 CK bridges the gap between foundational sciences (Step 1) and practical, supervised patient care. Before 2020, the Step 2 exam consisted of both the CK and Clinical Sciences (CS) exams; however, due to COVID-19, it was paused in 2020 before being permanently terminated in 2021. Scores for Step 2 are given in a 3-digit format, and 2022 saw a change in the pass score from 209 to 214. Getting a strong score during this exam is essential for residency applications as it shows your clinical acumen and readiness for patient-centred roles in residency training.
Exam format and structure
Step 2 CK is a nine-hour computer-based exam that takes place in a single day. It is a multiple-choice exam of 318 questions divided into eight 60-minute blocks, with each block not having more than 40 questions. The exam allows for a 45-minute break and gives 15 minutes for a tutorial that experienced candidates may choose to skip. You can get extra time for breaks if you finish a section early or have the 15 minutes from the optional tutorial added.
Step 2 CK is structured around a comprehensive and integrated content outline, categorising material into 18 major groups. These categories are designed to reflect concepts and principles that span multiple organ systems or are specific to individual ones. The exam includes questions from various disciplines, such as internal medicine, obstetrics and gynaecology, paediatrics, preventive medicine, psychiatry, surgery, and other fields essential for supervised patient care.
The test challenges candidates to apply their knowledge in practical ways, often requiring the interpretation of complex data. You may encounter tasks involving the analysis of tables, laboratory results, diagnostic imaging, or photographs of pathological specimens at both gross and microscopic levels. Other diagnostic studies are also integrated into the exam to assess your ability to synthesise information and make informed clinical decisions.
Important dates for 2025
Similar to Step 1, there is no set date for the Step 2 CK exam; rather, you select a three-month window in which you would like to write the exam. Step 2 is offered worldwide, and the location where you choose to write the exam will determine the available dates that will be given to you. It will be up to you to pick the day that works for you. Applying and scheduling the exam early increases your chances of securing your preferred test date and location; the catch is you can’t book more than six months in advance.
How to register
Contrary to popular opinion, you can apply for the Step 2 CK exam without writing the Step 1 exam. First, you must register through the appropriate entity. U.S and Canadian medical students should register with the National Board of Medical Examiners (NBME), while International medical graduates register through the Educational Commission for Foreign Medical Graduates (ECFMG). Once your application is approved, you will receive a scheduling permit via email containing your eligibility period, the 3-month window during which you must take the exam.
The next step is to go to the Prometric website and input your scheduling permit number as well as your first and last name. You will be given a list of available locations, and after you pick one, you will be shown the available dates for that location. However, before your application will be processed, you must pay a standard exam fee. Starting from January 2025, The examination fee for the USMLE Step 2 CK will be $1,020 for exam registration. There is also an international test delivery surcharge of $230, and should you need to reschedule, you can do so for a fee of $100.
Tips for scheduling
Planning and scheduling your USMLE Step 2 CK requires thoughtful preparation to ensure a smooth and stress-free process. The first step is deciding when to take the exam. Popular periods, like summer or dates close to residency deadlines, often fill up quickly. To secure your preferred eligibility period, submitting your application at least 6–8 weeks in advance is crucial, allowing time for processing and avoiding last-minute stress, especially if you are an IMG, as the ECFMG may take a few weeks to verify your documents.
Ensure all your documents are in order before applying. U.S. and Canadian medical students can obtain certification directly from their schools, while international graduates must coordinate with the ECFMG to verify their credentials. Ensure that your government-issued ID matches the name on your application to prevent delays with your application. Inconsistencies in your information will cause unnecessary setbacks and prevent you from writing the exam on your preferred date.
Financial planning is equally important beyond the exam fee, and you should also factor in potential additional costs, such as eligibility extensions or rescheduling fees. While you may not have a lot of choice, you should pick a location that will require the least amount of travel for you; this will allow you to cut costs on transportation and accommodation. Be sure to visit the location before the exam to ensure you have no issue reaching it. Choose an eligibility period that aligns with your study schedule and avoids major personal or academic commitments to maintain flexibility for unexpected delays.
