APPA CAS Technical Requirements

Compatible Browsers

A web browser is the program your computer uses to connect to the Internet and access the application.

Chrome and Firefox (Preferred)

For the optimum experience, we recommend using the most current version of Mozilla Firefox or Google Chrome, which work on both Macs and PCs. You can download these browsers for free here:


Safari is the default internet browser for Apple products and is compatible with the application. If you encounter any difficulty while using the most up-to-date version of Safari, try switching to Chrome or Firefox.


Edge is Microsoft’s most recent browser and is compatible with the application. If you encounter any difficulty while using the most up-to-date version of Edge, try switching to Chrome or Firefox. 

Internet Explorer

As of June 26, 2020, all versions of Internet Explorer, including Internet Explorer 11, are incompatible with the application. Switch to a supported browser to access the application.


If you are having difficulty loading application pages:

  • Ensure you are using the most current version of a compatible browser. 
  • Confirm that Cookies, JavaScript, and Pop-ups are enabled within your browser. 
  • Be aware if you are using public Wi-Fi (e.g., libraries, coffee shops), connection speeds may slow down the application.

To determine your browser's version, and to confirm that Cookies, JavaScript, and Pop-up windows are enabled, visit  

Mobile Device Accessibility

You can view and edit your application using a compatible browser on your smartphone or tablet. If you encounter any difficulty while using your mobile device, try switching to the Chrome or Safari mobile browser.

However, for an optimal experience – and when completing sections with many fields (e.g., transcript entry) – we recommend you use a computer. 

Email Notifications

Emails can sometimes get flagged as junk or spam, which prevents them from appearing in your inbox. To ensure you receive email notifications, including notifications from the programs you are applying to, you may need to designate us as a trusted source through your email provider. Use these links to obtain your email provider's safe-listing instructions:

If you encounter any difficulty when using a Microsoft-based email provider (e.g., Outlook, Hotmail, MSN, etc.), try switching to a Gmail or Yahoo account. Additionally, if using a school-based account (i.e., .edu), be aware that some schools may disable your account after graduation. We recommend switching to a Gmail or Yahoo email address if applying after graduation.

Safe-List Email Addresses

Ensure the following email addresses and email domains are safe-listed:
