Frequently Asked Questions

• Q: How does ResidencyCAS improve the application experience for applicants?

  ResidencyCAS offers a mobile-friendly, user-centric platform that streamlines the residency application process—from submitting applications and credentials to managing interviews and rank lists. This allows programs to offer applicants more holistic reviews of all components of their applications.

   

• Q: How does ResidencyCAS improve the way obstetrics and gynecology residency programs process applications?

  ResidencyCAS helps programs apply data science to better identify alignment with applicants, streamline staff workflows, and enhance holistic review—at no cost to programs. It also offers essential tools and support to improve the review and selection process and applicant experience. This is especially important as resources and staffing available onsite for programs are frequently limited.

   

• Q: How much does ResidencyCAS cost for the applicant?

  ACOG’s work on ResidencyCAS brings tremendous value across the interview season experience for the whole of our obstetrics and gynecology medical education community. For applicants, this increased value comes from both system improvements and reduced application costs. Tools like program signaling have already lowered the average number of applications submitted. ACOG has further reduced the cost faced by applicants through a ResidencyCAS pricing model designed to align with OBGYN’s approach to signaling. See the pricing chart below.

  Number of Programs	Application Fee
  Up to 18	$99
  19–30	$18 per application
  31 or more	$23 per application

   

  Additionally, ResidencyCAS brings tremendous value to our residency program community as it allows for meaningful holistic application review; provides a powerful, web-based experience; facilitates an application and interview season carried out on a single, user-friendly platform that is efficient, effective, and engaging; and provides all of these benefits at no cost to residency programs.

• Q: Is ResidencyCAS used by other specialties?

  ResidencyCAS is currently in use by OBGYN and Emergency Medicine.
  ResidencyCAS is structured on the centralized application service technology platforms offered by Liaison (the platform’s host company) and used by numerous health professional training and education programs, including dental education, osteopathic medical schools, physical therapy programs, pharmacy and veterinary schools, and many large-scale state systems and graduate education institutions. With over 30 years of experience, Liaison has successfully onboarded more than 40,000 programs to the platform and processes approximately 3.5 million applications annually using its centralized education service technology.

   

• Q: What motivated the move to ResidencyCAS from ERAS?

  The move to ResidencyCAS was driven by the OBGYN community’s commitment to creating a more transparent, equitable, and data-informed residency application process. Through the Right Resident, Right Program, Ready Day One initiative, funded by the AMA’s Reimagining Residency grant program, the specialty recognized an opportunity to design an application system that better supports holistic review, improves alignment between applicants and programs, and enhances the overall transition from medical school to residency.

   

• Q: Do multispecialty applicants still have to use ERAS for applying to other specialties?

  Yes. ResidencyCAS only supports applications to obstetrics and gynecology and emergency medicine residency programs.

   

• Q: Is partners / couples matching still available for obstetrics and gynecology applicants?

  Yes. Matching as a couple remains fully available for obstetrics and gynecology applicants. ResidencyCAS is used only for the application and interview process. The Match itself—including participation as a couple—is conducted through the National Residency Matching Program (NRMP) and remains unchanged.

   

• Q: How can applicants and residency program staff learn more about how to use ResidencyCAS?

  Applicants and residency program staff can learn more about ResidencyCAS by visiting www.residencycas.org, which offers guides, training materials, and recorded webinars. ACOG also hosts a series of webinars tailored to help residency program staff, applicants, and advisors familiarize themselves with ResidencyCAS. Liaison International, ACOG’s partner in developing the platform, provides direct support to program staff as they customize the platform to meet their needs. Additionally, attendees at the CREOG APGO Annual Meeting are encouraged to participate in one-on-one and in-person sessions with Liaison International’s experts.

   

• Q: Can applicants use ResidencyCAS for obstetrics and gynecology subspecialty fellowship applications?

  No. Currently, ResidencyCAS supports only obstetrics and gynecology and emergency medicine residency programs. However, an equivalent platform—FellowshipsCAS—will be used beginning in 2026 for some obstetrics and gynecology subspecialty fellowship applications, starting with Complex Benign Gynecology (CBG, formerly known as MIGS) and Pediatric and Adolescent Gynecology (PAG).

   

• Q: When does the information from an application cycle get archived? Will I continue to have access to the applicants’ information once the next cycle opens?

  Yes. You’ll always have access to your own applicant data in ResidencyCAS including previous cycles.

   

• Q: Will evaluation forms I create in ResidencyCAS for my program in the previous cycle transfer to the next cycle?

  Yes. Any settings or forms you previously created for your program’s use will be accessible for reuse in the new cycle.

   

• Q: Do programs need to update their information every cycle?

  Yes. Every year in March, ACOG will send emails to programs confirming the program director and program manager contact information and program type to ensure that information is complete and ready for the next cycle in ResidencyCAS. For updates throughout the cycle, please contact CREOG Director Allison Whitney at [email protected].

   

• Q: When does the OBGYN residency application cycle open?

  Each year, the cycle opens in early fall. This date will be communicated to programs ahead of time. The 2025–26 cycle begins on October 1, 2025.

   

• Q: Are training workshops and one-on-one training sessions available?

  Yes. There will be a schedule shared each April with trainings to address program needs. There will also be in-person workshops and one-on-one trainings available at the annual CREOG Education Retreat. Additional one-on-one sessions can be arranged individually with Liaison.

   

• Q: When will I learn about system enhancements for the following cycle?

  Details about the enhancements made in each cycle will be announced at the annual CREOG Educational Retreat as well as during upcoming webinars and training workshops held during the summer or early fall of each year.

   

• Q. I’ve heard about holistic review in the application process. What is holistic review?

  Holistic review is a mission-driven approach to reviewing applicants based on their experiences, attributes, and academic achievements within the context of their own unique and full life journey as shared in their residency program application. ResidencyCAS supports holistic review by helping programs to define and weigh their own mission-aligned criteria, facilitating fair, consistent, and comprehensive review of applicants applying to their programs.

   

• Q. What is Alignment Insights?

  Alignment Insights is a data visualization tool in ResidencyCAS that is specifically designed to help applicants see how their own experiences and interests align with those applicants previously selected to interview in the prior year(s) at residency programs. This data driven visual tool helps applicants to make more informed and strategic application decisions and can help to inform the placement of program signals for applicants.

   

• Q. Does the ResidencyCAS Program Portal use Artificial Intelligence (AI)?

  No. The ResidencyCAS Program Portal uses data science and structured analytics—not artificial intelligence—to provide insights and visualizations that support holistic, human-driven decision-making.
