About CritABCD
CritABCD (also written Crit ABCD, and found at critabcd.com) is a learning site for the IB Middle Years Programme. It is built around the four assessment criteria, A, B, C and D, that every MYP subject is marked against. The name comes from there: Criteria ABCD.
WHO IT IS FOR
Students who want to know what a good answer looks like and practise it, and teachers who want tools to run a class, see where each student is, and give feedback against the criteria. It covers Physics, Chemistry, Biology, Individuals and Societies (Humanities), Geography and Design.
FREE TO USE, NO SIGN-UP
ON THE PLATFORM
Timed MYP papers and topic practice, marked against criteria A to D with feedback tied to each one rather than a single percentage.
Teachers host a live session students join with a code. Activities can run in step or at each student’s own pace.
A guided Design module and live activities that follow the design cycle from inquiring through to evaluating.
Set a class, assign work, see how each student is progressing, and download a student’s work as a PDF organised by criterion.
A NOTE ON THE IB
CritABCD is an independent learning site. It is not the International Baccalaureate and does not host the IB’s own subject guides; our guides, questions and examples are written in our own words, and each guide links to the official IB source. Your teacher marks against the official IB level descriptors.
