Postgraduate Training Authorization Letter (PTAL) or “California Letter”

ERAS Document Submission At-a-Glance

Click to view

If you apply to programs in California, you must submit a Postgraduate Training Authorization Letter (PTAL) issued by the Medical Board of California with your residency applications. The PTAL may also be referred to as the “California Letter.”

The Medical Board of California will require several months to issue the PTAL. You should contact the Medical Board of California for information and apply for the PTAL well in advance of program deadlines.

IMPORTANT NOTE: The Medical Board of California has established additional criteria with respect to international medical schools for the purpose of eligibility for medical licensure. If you plan to apply to residency programs in California, consult the Medical Board of California to determine if graduates of your medical school are eligible for licensure in California. ERAS does not preclude any students/graduates from participating in ERAS, based on their eligibility for licensure. Before applying to residency programs in any state, it is your responsibility to become familiar with that state’s licensure requirements and to ensure that you meet any licensure requirements to enter and complete residency training in that state.

In AAMC’s MyERAS, you must assign the PTAL as one of your documents in your applications to programs in California. Indicate on the Additional Documents page in MyERAS that you will be using a PTAL.

Once you obtain the PTAL, upload it to ERAS Support Services via ECFMG’s OASIS. Documents uploaded through OASIS will take up to five business days to process. If your medical school participates in EMSWP ERAS and will be providing the PTAL on your behalf, the school can upload it using EMSWP. Documents uploaded through EMSWP will take up to two business days to process. See Document Submission for more information.

If you do not yet have your PTAL, you need to let programs in California know that you are working to obtain one. To do this, indicate in MyERAS that you will provide a PTAL, and upload a temporary document, such as the receipt issued by the Medical Board of California or the “Originals Returned” letter that accompanied your returned originals, via ECFMG’s OASIS. When you receive the final PTAL, upload a copy to ERAS Support Services at ECFMG via OASIS and it will replace the previous temporary document on file.
