Prove
All Portfolios

For IB schools

CAS sign-offs, without the chasing.

Problem: Coordinators spend weeks chasing supervisors for proof.

Fix: Supervisors confirm with one tap. You see every gap on one screen.

What you'll prove

Who is it for?

IB schools and their CAS coordinators. It runs alongside ManageBac or Toddle.

What does it cost?

31-day free trial. No card needed. The clock starts at your first student invite. Then $99 a month, locked, for the first 100 schools that join by 31 December 2026. After that, $199 a month for up to 180 DP students, or $299 above that. A year costs 10 months.

Who confirms my work?

The supervisor who saw the activity. They tap one link and need no account.

Who sees it?

The student, their supervisor and your coordinators. Under-18 work never gets a public link.

What's free and what's paid

Free for every student and supervisor, always

  • Logging CAS experiences
  • Tag the seven learning outcomes
  • The supervisor ticks the outcomes they saw
  • Reflections, private to the student, their supervisor and the coordinator
  • The student's own “what needs you today”, and nudging a supervisor by WhatsApp or link
  • One-tap supervisor confirmation, with no account
  • The student's own record, to keep
  • The student's own print view
  • Join links
  • The school's full export (CSV and print), in every plan state

Paid, per school

The coordinator's tools: roster, gaps, the sign-off queue, interviews, the completion checklist, invites and roles. Unpaid, they stay visible but read-only. Your export is never paywalled.

  • Roster
  • Gap counts and flags
  • The pending sign-off queue
  • The three CAS interviews, recorded per student
  • The completion checklist, the CAS Project check and the completion list
  • Bulk invites
  • Role management
  • The principal summary
  • League visibility

The overview, and three CAS policy templates you can edit. No email needed.

For your IT team: the Data Processing Agreement and the setup notes.
