Core Rostering is the foundation of every EdTech integration. It answers the essential questions: who students are, which classes they’re in, and how applications connect to school systems. But Core Rostering alone doesn’t provide the full academic context modern EdTech products need.

Extended Data Domains build on Core Rostering by delivering additional student, school, and academic data — published through open standards — without adding new integration complexity. 

In short: Core Rostering gets you connected; Extended Data gives your application the context to do more.

Beyond Core Rostering

Core Rostering defines who students are and which classes they’re in. But it stops short of providing the broader academic and operational context most EdTech products rely on.

Extended Data Domains expand beyond Core Rostering by delivering student, school, and academic data that falls outside standards like OneRoster. At Ednition, we align these data to the Ed-Fi Data Standard, allowing data to be published consistently through open standards without introducing custom schemas.

Extended Data Domains help your application understand:

• When instruction occurs
• How students are performing
• Whether students are attending
• What academic or behavioral events are happening
• How students are progressing toward graduation

Powered by the Ed-Fi Open Data Standard

RosterStream’s Extended Data offering is built on the Ed-Fi Unifying Data Model (UDM) - a data standard developed by the Ed-Fi Alliance. Ednition builds RosterStream on trust, open standards, and interoperability.

Ednition’s Pragmatic Release Path of Extended Data Domains in RosterStream

The Ed-Fi data model includes data domains spanning academics, operations, and student outcomes. We are delivering these data domains incrementally, based on vendor demand and real-world use cases. Here’s a quick summary of our release approach:

1. Start with CSV ingestion and mapping.
2. Expand to API connectors as needs grow.
3. Add new domains without rebuilding integrations.

Our phased approach lets vendors move quickly today while preserving a clear path toward deeper, more automated data publishing over time.

Comprehensive Coverage Beyond Core Rostering

Extended Data Domains expand integrations beyond basic rostering into areas that power real classroom and district decisions.

Calendar

‍The Backbone of the School Year. Standardizes how time is defined—from instructional days to sessions—so all academic data is anchored in the correct context.

Bell Schedules

‍Structure the Instructional Day. Represents daily schedules, passing times, and alternate day patterns to ensure instructional minutes and attendance are modeled accurately.

Attendance

‍Granular Attendance Data. Move beyond present/absent counts to capture attendance at both the day and class-period level.

Discipline

‍Behavioral Events and Outcomes. Capture behavioral incidents and administrative responses to support climate analysis, compliance, and equity reporting.

Assessment

‍Normalized Assessment Results. Standardize results from state, district, and classroom assessments to support performance analysis and instructional planning.

Student Academic Records

‍Academic History Over Time. Aggregate grades, credits, and course history to provide a longitudinal academic record.

Graduation Progress

‍Progress Towards Completion. Track graduation plans, credit accumulation, and milestones to ensure students remain on track.

What Extended Data Domains Enable for EdTech Vendors

Extended Data Domains change what your product can understand — without changing how you integrate. With access to attendance, performance, schedules, and academic progress, applications move beyond static roster-based assumptions and respond to what’s actually happening in schools.

For vendors, that means:

• Context-aware product behavior: Applications can adapt to attendance patterns, academic progress, and instructional timing — not just enrollment snapshots.
• Fewer custom integrations: Vendors avoid building and maintaining district-specific connectors for each new data type or use case.
• Faster product development: Engineering teams spend less time modeling district data and more time shipping features customers actually care about.
• Alignment with district priorities: Attendance, assessment outcomes, and graduation progress are central to how districts evaluate impact — Extended Data Domains make those signals available without bespoke work.
