Understand what document numbers, QR codes, watermarks and digital signatures can tell you, with interactive examples and practical steps when details do not match.

Start with what learners can do. Run a small trial and use evidence before expanding across a school.

Screen size is a starting point. Test real files, seats and devices, then consider the cost of operating the room.

Turn an introduction into a fit assessment with a one-page brief, better questions and an explicit next step.

Choose one problem, remove duplicate work and plan for learners with different access needs.

Plan audio, shared content and turn-taking, then capture decisions everyone can act on.
