Technology Requirements

CDLS uses two Learning Management Systems (LMS) that integrate with a Student Information System (SIS) for single sign on (SSO) functionality.


For optimal performance Schoology (LMS) recommends upgrading to the latest versions of the supported browsers and additional requirements below. The information here is provided by Schoology.

Recommended Browsers:

Additional Requirements:

  • Flash 9+ Download the latest version

  • Cookies enabled
    Websites often store cookies and other data as you browse online. This data may include information that you have provided in the past, such as your name, email address, and preferences. This data helps websites such as Schoology identify you when you return to the site, and helps the site remember the user's preferences or registration details for a future visit. On Schoology, enabling cookies in your browser can help prevent login issues to third party apps that provide course content. 


If you are using the mobile app, please make sure you are using the latest version.


iOS: Download the latest version from the App Store. If you have already installed the app, you can find the version number by opening Settings on your iPhone or iPad, and tapping Schoology in your list of apps.


Note: Schoology strongly suggests that iOS users upgrade to the latest version. Schoology only supports the latest 3 versions of iOS. 


Android: Download the latest version from the Google Play Store or Amazon Appstore. Once you have installed the app, you can find the version number by opening Settings on your Android device, tapping Application Settings and then Manage App.


Note: Schoology strongly suggests that users upgrade to the latest version. Schoology supports the latest 5 versions of Android. 

Web - Info for School IT Admins

The following tasks are recommended for optimal performance:

  • Add * to your whitelist. 

  • Check your firewall settings for blocks against common URLs.

    • Additionally, if your school has firewall blocks against Google Ad Services, it will cause Schoology to be very slow. This is because Schoology has Google Ad tags incorporated into our site so that you, as a current Schoology user, do not see Schoology advertisements elsewhere on the internet. These tags do not track any personally identifiable information or any other sensitive data. Remove any blocks against Google Ads Services for optimal performance.

  • Ensure outgoing traffic rules for ports 80, 443, 8080, 8443, and 1935: 

    • Ports 80 and 443 are used for standard Schoology web traffic.

    • Ports 8080 and 8443 are used to load SCORM content from Schoology.

    • Port 1935 is used for recording audio files.

  • If your SIS requires you to explicitly allow a Schoology-specific IP address as part of your firewall rule to integrate your on-premise SIS with Schoology, please add the following IP addresses to the rule.
