Determining your Blackboard LTI tool version

Depending on your institution's configuration, you may be launching Gradescope from Blackboard using LTI version 1.3 combined with Blackboard's custom API.

An application programming interface (API) is a type of software that allows two apps to communicate with each other. Learning Tools Interoperability (LTI) is a type of software developed by IMS Global Learning Consortium specifically to allow learning systems, such as Blackboard, to communicate with external systems, such as Gradescope.

Because the process for using Gradescope with Blackboard can differ slightly based on which integration version you have, it's recommended that before you start using our LTI guides,  you use one of the methods below to figure out whether your institution is launching Gradescope with LTI 1.0 + API or with LTI 1.3.

  • Method 2: Check your assignment-linking capabilities.

    • In Blackboard Ultra, go to your course homepage, click the + button under Course Content, click Content Market, and see if Gradescope Assignment is listed as a content option. If Gradescope is listed as a linkable content option under Build Content or Gradescope Assignment is listed in the Content Market, then your institution is most likely using LTI 1.3. If not, you're most likely using LTI 1.0 + API. Keep in mind that this is not a foolproof method and the best option is to contact either your admin or
