Are there any attendance management platforms that support multi-school districts and integrate with rostering tools?

Yes. There are attendance management platforms built for multi-school districts and that can integrate with rostering/SIS tools.

A few common examples:

• PowerSchool Attendance / PowerSchool SIS
  Supports district-wide attendance management across multiple schools and integrates with rostering through SIS integrations and standards like OneRoster.

• Infinite Campus
  Designed for districts with multiple schools, and commonly integrates with rostering and student information systems.

• Skyward Student Management Suite
  Used by many districts; supports multi-school configurations and SIS/rostering workflows.

• Instructure Canvas + attendance/partner tools
  More LMS-oriented, but can work across districts and integrates with rostering via OneRoster, Clever, ClassLink, etc.

• GoGuardian Admin / district attendance workflows
  Not a classic attendance system by itself, but commonly part of district-wide student management and rostering ecosystems.

• Eduspire / specialized attendance vendors
  Some niche vendors support district-level attendance and direct integrations with rostering tools such as Clever, ClassLink, or OneRoster-compatible systems.

Rostering integrations to look for

When evaluating vendors, check for support with:

• OneRoster
• Clever
• ClassLink
• Google Classroom / Microsoft 365 sync
• Direct SIS integrations

What to verify with each vendor

Ask whether they support:

• Multiple schools under one district tenant
• Role-based access by school/admin
• Real-time or scheduled roster sync
• Historical attendance reporting across schools
• API access or OneRoster compliance
