Track progress

A live progress chart shows your SCI trajectory across all skills. Set goals and measure growth.

One record. Every skill connected to its evidence.

The Passport gives each skill a clear home. Open a record to understand what was demonstrated, where the evidence came from, and when it was last updated.

01

Start from a claim

A skill begins as something you say you can do. Copy and interface both keep that distinct from a skill with evidence behind it.

02

Connect the evidence

Assessments, coursework, projects, teaching activity and workplace contributions attach to the skills they support, with their source and date intact.

03

Share what you choose

Publish a full Passport or a focused view of selected skills. A viewer opens a skill and follows it back to the records behind it.

Peer session completions
AI tutor assessments
Peer reviews and endorsements
External proofs and certificates

Four sources of proof.

Your passport accepts evidence from multiple sources. Each type contributes differently to your SCI score, creating a multi-dimensional view of your skill credibility.

Signed Passport document

Every credential in your passport is backed by an append-only event chain.

Portable anywhere

Share via link, embed on your site, or let companies verify through our API. No lock-in.

Growing with you

Your passport evolves with every session, assessment, and endorsement. Never static.
