Deprecation Notice for OneRoster 1.0

4 June 2018
The initial publication of OneRoster® (version 1.0)—one of IMS Global’s most impactful and widely adopted standards—has achieved its primary goal to streamline the rostering of students in digital learning apps.
Through the leadership of IMS members, the standard has evolved to provide full student lifecycle and two-way data synchronization beyond enrollments to include student information, learning resources, assignments, and grades—available in OneRoster 1.1.
Interoperability relies on market alignment to standards. The widespread adoption of OneRoster 1.1, along with a relatively simple upgrade from 1.0, led the OneRoster Product Steering Committee to recommend deprecation of OneRoster 1.0.

OneRoster 1.0 Scheduled Deprecation

Effective January 1, 2019, IMS Global will no longer offer new certifications for OneRoster 1.0. 
Re-certifications for OneRoster 1.0 will be accepted through December 31, 2018.
IMS Global recommends that certifications initiated from the date of this announcement—June 4, 2018—forward should be for OneRoster 1.1.
OneRoster 1.1 is the stable and currently recommended version of OneRoster. Procurement language requesting conformance certification can be found here.
