Cycle Timeframes

Program Participation Requirements

Liaison requires all programs to designate two contacts at your institution who will receive all communication from PostbacCAS, including the configuration, application, and WebAdMIT launch notifications.

Applicant Portal

The first three sections of the PostbacCAS application (i.e., Personal Information, Academic History, and Supporting Information) compose the core application. They contain questions that are commonly asked of applicants across all participating programs, such as an applicant's biographic information, standardized test scores, and experiences. The fourth section of the application is Program Materials, which is customized by you through the Configuration Portal (discussed in the next section).

You can access the PostbacCAS application and PostbacCAS Applicant Help Center to review the applicant experience. You can also create a test application in the Applicant Portal; we recommend creating a new account and adding "test" to your name (e.g., TestJohn TestDoe).

For a general overview of the applicant experience, review the following documents:

Applicant Processing Reference Guide: learn how applicants move through the application and Liaison processes applicant materials, such as transcripts and official test scores.
Application Statuses Reference Guide: review what each application status means and how you can interact with applicants at different stages.
- Review the requirements for the PostbacCAS Complete application status.
PostbacCAS Quick Start Guide and FAQs: a suggested timeline for completing and submitting the application, links to important pages including cycle dates and fees, and a FAQs section.

You can direct any applicant inquiries related to the application to PostbacCAS Customer Service.

Configuration Portal

Once you've configured your program, you'll need to have it approved by the account team before it is available to applicants.
