Gradescope offers a LTI 1.3 integration with other LMSs, but not Blackbaud. Our teachers would be more likely to use Gradescope if it integrated in Blackbaud.
Gradescope has said that I could try to use the Gradescope LTI 1.3 integration with Blackbaud, but that it might not work correctly since it is not set up in Blackbaud. I am hesitant to set something like that up if it won't work properly. I would like to request that Blackbaud offer this integration. Here are their instructions for LMSs that would like to offer this integration per their article https://guides.gradescope.com/hc/en-us/articles/21746972015117-Configuring-Gradescope-LTI-1-3-in-Other-LMSs: "
If you are an LMS tool provider, and wish to integrate with Gradescope, please contact partnersupport@turnitin.com directly. If you are an institution and using an integration that is not listed on our help center, please contact your LMS provider and have them contact us via the above address."
