APPA CAS Postdoc Application Information

APPA CAS Application for Psychology Postdoctoral Training

The APPA CAS (APPIC Psychology Postdoctoral Application) is highly flexible to meet the needs of a wide range of postdoctoral programs requiring basic demographic, internship and postdoctoral programs information, and letters of recommendation while allowing multiple uploads to be defined by individual programs. APPIC believes the APPA CAS provides a significant contribution to postdoctoral training offering a more unified and user-friendly application process for applicants and programs. APPA CAS provides a more coordinated review of applicant information and reduced costs and time for applicants.


Access APPA CAS as follows:

APPLICANT PORTAL: If you are an applicant, click here to access the APPA CAS Applicant Portal to create and develop your application. We strongly recommend that you read the general instructions upon entering the portal (see the "Instructions" link on the left). As you enter different sections of the APPA CAS, you should click the "Instructions for this section" link in the upper right portion of each page. As you work on your application, be sure to click the "SAVE" button at the bottom of each page in order to save your work.

REFERENCE PORTAL: This portal is for individuals (e.g., internship training director, faculty, supervisors) who are providing letters of reference for students. Once a student has designated you to APPA CAS as someone who will be providing a letter of reference, you will receive an e-mail that contains links and instructions for accessing the APPA CAS Reference Portal. If you are providing a letter of reference and have already received your login information via e-mail, click here to access the APPA CAS Reference Portal.

CONFIGURATION PORTAL:  This portal is for Training Directors to use to configure their portal in WebAdmit.  Training Directors will ONLY use WebAdmit to configure their portals. It is no longer used for selection or application review.  More information can be found on the following site - APPA CAS Portal Quick Start Guide.

ADMISSIONS PORTAL This portal is for Training Directors and postdoc program reviewers to access and review applications.  This new APPA CAS portal is called "Outcomes," and is nearly identical in appearance to the portal used for the internship AAPI. You can either use this universal Outcomes link ( or you can use log in using your organization-specific Outcomes link that you would have accessed upon setting up your account.

AAPI and APPA users: Please note that when you log in using the universal Outcomes link (, your Dashboard will always default to showing you the first Centralized Application Service (CAS) that you set up (APPA CAS or AAPI).  However, users can easily toggle between APPA CAS and AAPI by clicking their Profile initials at the bottom left of the screen and selecting View My Organizations.  You can then select whether you want to review AAPI or APPA CAS applications.

If you have not used APPA CAS previously, instructions how to register your program can be found at the bottom of this page.

Here is an overview of the process:

  1. Applicants access the APPA CAS via the "Applicant Portal," which means that they will use their internet browser to create an account, enter information into the various fields of the APPA, and ultimately submit their completed application to postdoctoral training sites.
  2. The applicant will also request letters of recommendation by generating electronic requests (via e-mail) to individuals of her/his choosing. These individuals will upload their letters directly into the APPA CAS. While the applicant will not be permitted to view the content of the letter, she/he may attach it to as many or as few applications as desired. In other words, the applicant can decide which letters of reference are submitted to each internship site. 
  3. The applicant also submits one official copy of all graduate transcript(s) directly to the application service via regular mail. These transcripts are verified as official, scanned into the system, and attached to each application that is submitted by the applicant. Undergraduate transcripts are not required.  Some universities will not separate the undergraduate transcripts from the graduate transcripts and these are permissible. Please send your transcripts to: APPA CAS Transcript Department at P.O. Box 9131, Watertown, MA 02471. Use the following link for more information transcripts US and English-Canadian Transcripts - Liaison (
  4. Once an applicant has completed all aspects of the application, she/he chooses the "designated" sites to which the application is submitted electronically. The applicant has the flexibility to decide which cover letter, essays, letters of recommendation, CVs and if requested, supplemental materials are submitted with each application.
  5. Once submitted, the application is instantly available to the postdoctoral training site for review. Training Directors and selection committees may review applications online, sort and select applications based on various criteria, and download application information in various formats.
  6. An application can be submitted or designated before transcripts are verified. Programs will be able to see the application under the "received" designation.
  7. Sample APPA CAS from 2020-2021


  • For the 2023-2024 selection cycle, use of APPA CAS is free to both programs and applicants.  There is no fee to submit an application, though your university fee for requesting a transcript will apply.
