Schools teach a pupil to build a cabinet, wire a circuit, write a proof or run an experiment — and then have nothing to show for it that an outsider will believe, because the school marked its own work. JitGuru is the other answer: an independent expert reviews the pupil's actual work and writes up what they can do.
That expert is you. Not a teacher of theirs, not an examiner for a test board — somebody who does the thing and can tell whether it was done well.
Anyone with real expertise and the judgment that comes with it:
No teaching qualification is required unless a particular school asks for one. What every school wants to know is that you know the subject and that you are not connected to the pupil.
The subject, the milestone, how many pupils, and what that school counts as mastery. Schools set their own standard — JitGuru does not rank evaluators or filter them for a school, and it does not set the bar.
A portfolio, a project, a build, a recording, a written argument — whatever the pupil actually made. Remotely on your own time, as a live defence where the pupil presents and answers for it, or both. It is not teaching, and it is not marking a test.
Against the school's criteria, in your own words: what they showed, what is still thin, what you would want to see next. That write-up becomes a — a record the family reads and a funder or accreditor will accept.
Microschools, learning co-ops, homeschool groups, hybrid and independent schools — any school that teaches to mastery and wants an outside expert to confirm it. They come to JitGuru to find someone like you, for one pupil or for a whole cohort.
JitGuru is young, and most schools start by inviting an expert they already trust. If somebody sent you this page, make a profile and tell them — they can put you straight onto the work.
