Welcome to ResidencyCAS!

The Residency Centralized Application Service (ResidencyCAS) streamlines the application process for programs. Simply submit one application with all necessary materials through ResidencyCAS. Your application and materials are then transmitted to all programs you choose to apply to.

In the ResidencyCAS application process, you're required to input key information and complete several important tasks. This quick start guide provides a set of useful resources you can use to complete the process.

Accessing the Application

To create an account, you'll need to obtain an individual access link:

  • US fourth-year students and graduates (MD or DO): contact your degree-granting medical school.
  • International medical graduates (IMGs): contact ECFMG.

Once you have your access link and create your account, you may want to bookmark the application URL: https://residencycas.cas.myliaison.com/.

    Overview Video

    Note: while this video states applicants receive a link to the ResidencyCAS application from their medical school dean, IMGs and Canadian medical graduates receive the invitation from ECFMG, and not from their medical school dean.

    On June 1, 2026, we hosted a webinar, "ResidencyCAS Applicant Webinar, 2026–2027 Cycle Overview," that covered the ResidencyCAS application process, important dates, and guidance on navigating the application experience.

    Specialty-Specific Guidance

    OB/GYN Deadline Guidance

    Applicants are strongly encouraged to submit their application and all supporting materials by the published application deadline. While ResidencyCAS permits submission after the deadline, applicants should understand that many Obstetrics and Gynecology residency programs begin their review process immediately upon receiving access to applications and may not routinely review applications or newly received materials submitted after the stated deadline. Late submission of an application or supporting documents may therefore limit an applicant's opportunity for full consideration. To ensure the broadest possible review by programs, applicants should plan to have their application and all available supporting materials submitted by the deadline. 

    Emergency Medicine Deadline Guidance

    Applicants to emergency medicine and EM combined programs are encouraged to submit their applications by the recommended submission date to ensure that they are available to programs to review at the start of the application review season. Emergency Medicine and EM Combined programs are aware that many aspects of the application, including the SLOE and some exam scores, may not be available to you by this date. Further guidance can be found in the EMRA Advising Guide or the CORD Medical Student and Advisor Resources page.

    Completion Requirements

    The following items and documents must be received along with your submitted ResidencyCAS application for it to be considered complete:

    Official medical school transcripts.

    Medical School Performance Evaluation (MSPE).

    USMLE and/or COMLEX transcript.

    ECFMG Status Report (IMGs only).

    Any required evaluations – check with your programs for specific requirements.

    Note the following:

    • Letters of recommendation and SLOEs must be manually assigned to your chosen programs in ResidencyCAS. These are the only components of your application that require manual assignment. All other requirements are automatically assigned to your selected programs.
    • A personal statement and headshot are required components of the application and must be fulfilled in order to submit your application.
    • Once you submit your application and meet all the requirements, your application status will be updated to "Complete."
    Application Signals

    Determine how you want to use signals to indicate interest in programs.

    Submitting Your Application

    Refer to the Application Cycle Dates for the recommended deadline and program review start date.

    After Submitting Your ResidencyCAS Application

    You'll receive a confirmation email acknowledging that your application was submitted. Note that submitting does not mean your application is being reviewed by your programs. Your application status transitions from "In-Progress" to either "Received" or "Complete" upon submission, depending on the materials already received.

    Monitor your documents and application status.

    Regularly check your email, voicemail, and postal mail for any communications from programs that might be sent outside of ResidencyCAS.
