Every certificate carries an ID. Enter it and you will see the project, the number the learner actually moved, the score against the published rubric, and the name of the human who certified it.
It checks: that a submission with this ID was assessed against the published twenty-point rubric, that both gates were cleared, what the learner measured before and after, and who certified it.
It does not show the learner's full name, school address, contact details or the underlying artefact. Those stay with the learner and their facilitator.
The rubric is public: artefact six, process and failures six, defence eight. A well-measured failure outscores an unmeasured success — a credential here can be earned by a change that did not work, measured honestly and defended. Read the rubric.
