What do I need to study for STEP 1?
Check our detailed blog post about the study resources for STEP 1.
What do I need to do to apply?
You would need to apply for USMLE/ECFMG identification number that can be used for all USMLE-related exams. Check our detailed blog post on how to apply for your first STEP exam.
After applying for certification, you need to verify your student or graduate status by your medical school, and upload any additional required documents. Afterwards, you get scheduling permits (a paper that has numbers that allow you to both schedule your exam and start your exam on your exam day). For more details, check our post about registering and scheduling your first STEP exam.
How much does STEP 1 cost?
The fee for STEP 1 is $975, along with an International Test delivery surcharge of $180 if you’re taking the exam outside of the US/Canada. Rescheduling, extension of eligibility period, changing of test centers all will incur extra charges.
How much should I score on STEP 1?
In STEP 1, a score of 250 and above is considered a good score for IMGs. Residency programs are less likely to score filter applicants with over 250. You must also know the average score for the specialty you are applying for, as they differ for different specialties. Competitive specialties have higher mean score for those who match, while have lower mean scores.
This graph shows the USMLE Step 1 Scores of International Medical Graduates who matched and did not match by specialty. As you noticed, there is a big difference between the different specialties.

STEP 1 will become pass/fail on January 26, 2022. Therefore, the value of STEP 1 score will transition to other aspects of your application.

Graduating from Eligible Medical School
For an international medical student to be eligible to apply to ECFMG Certification, their medical school should meet certain ECFMG requirements. The eligible schools are listed in the World Directory of Medical Schools .
“The ECFMG® has announced that, effective in 2024 (previously 2023), physicians applying for ECFMG Certification will be required to graduate from a medical school that has been appropriately accredited. To satisfy this requirement, the physician’s medical school must be accredited by an accrediting agency recognized by WFME.”
Research
To increase the chances of matching, many applicants perform between 6 months to 2-3 years of research, especially for competitive specialties.
Research opportunities are usually unpaid positions if you don’t have much research experience. Hence, it is important to have an adequate source of personal finances for living in the US.

USCE (US Clinical Experience)
USCEs are a necessary part of the US residency application. USCE can help you get Letters of Recommendation (LoRs), which will help you when you apply to residency.
Here are the types of USCE
Electives/Clerkships/ Sub-internships
The best USCE for an application is an Elective/Clerkship. Available only to those who have not yet graduated from medical school. More often than not, it provides a more personalized LoR. The cost of electives can vary between $100 – $5000 per 4-week elective.
Externships
Provides some type of hands-on experience for medical graduates. Usually not done in big university hospitals.

Observerships
Observerships are a good choice for medical graduates in which you observe medical care. Observerships do not allow you to interact with patients, however, they give you an opportunity to become acquainted with the US healthcare system and develop networking opportunities.
Telerotations
Telerotations became popular with the COVID-19 pandemic. Although telerotations are not as helpful as in-person USCE, they are better than nothing when you are trying to build your CV. Telerotations cost vary from free to $2000 a month.
To learn how to find USCE, check out this video:
ECFMG certification
Although you can apply to the MATCH® without ECFMG certification, it is highly recommended that IMGs apply with ECFMG certification. In order to match, IMGs must be ECFMG certified. Recently, there has been a change in the certification requirement after the cancelation of the STEP 2 CS exam. To check the six pathways for ECFMG certification, check this video
I hope this information helps you in your preparation for the long, but rewarding US residency journey.
