1EdTech standards

The Timeback APIs are built on 1EdTech standards. 1EdTech (formerly IMS Global) maintains the most comprehensive set of education interoperability standards.

Standard	What it enables	What you skip building
OneRoster	Sync students, classes, and enrollments with school SIS systems	Identity management, rostering pipelines, enrollment logic
LTI	Single sign-on launch from LMS platforms into your app	OAuth flows, session management, user provisioning
QTI	Interoperable question and assessment formats	Custom question schemas, scoring engines, item banks
Caliper	Standardized learning event stream for analytics	Event taxonomies, data pipelines, analytics infrastructure
CASE	Alignment to academic standards (Common Core, NGSS, state frameworks)	Standards databases, crosswalk mappings
CLR	Portable learner records across platforms	Transcript formats, credential verification

Timeback extends these standards where necessary to support learning science requirements (mastery thresholds, XP policy and validation, closed-loop validation) while maintaining compatibility with the base specs.

Standards let apps work together. A tutoring app can read progress from an assessment app because both use the same data model.
