One of the core services in the 1EdTech OneRoster standard. This service is used for the exchange of grade book information i.e. scores and results that have been awarded to students undertaking some form of assessed activity. A rich set of data can be exchanged about the Results, the set of Results for an assessment (LineItem), and Categories (collections of LineItems). The defined web service takes the form of JSON payloads exchanged by the communicating systems. At present this service is used extensively in the K-12/schools education sector.
