Learning Tools Interoperability® Gradebook Services 2.0
The Basic Outcomes service was introduced in LTI® v1.1 and provides a simple way to associate a single gradebook column with each resource link, allowing a tool provider to manage results in these columns as decimal values. This Version 2 Gradebook Services support extends the Basic Outcomes service and the Result Service included in LTI 2.0, and extends them to allow Tool Providers more control over the number of gradebook columns per resource link and the maximum points possible for each column. This document defines two new web services: a line-item service and a result service. All requests are secured using OAuth signatures generated with the existing LTI credentials. LTI Gradebook Services are based on IMS Learning Information Services (LIS).
