# The Public Trust Model for Digital > A capability and maturity model for public institutions — cities, crown corporations, provinces and government agencies — used to produce a self-administered Public Trust Maturity Scorecard across 40 capabilities in four pillars: Information Practice, Service Modernization, Digital Office, and Digital Platform. The assessment itself (profile, questions, and results) is per-organization and access-token-gated, so those pages are intentionally not indexed or listed here — see robots.txt. ## Pages - [Home](https://publictrustmodel.net/): what the model is, the four pillars, what a respondent receives, and why the target maturity level is 4, not 5. - [About](https://publictrustmodel.net/?r=about): the model's origin and who maintains it. - [Privacy](https://publictrustmodel.net/?r=privacy): what is collected, what is not, retention, and how sensitive findings (e.g. security posture) are handled. - [Contact](https://publictrustmodel.net/?r=contact): how to reach the maintainer. - [Begin an assessment](https://publictrustmodel.net/?r=start): starts a new, self-administered assessment.
