- Who is the Comparative Judgement poster for?
- Comparative Judgement belongs to the Education section rather than to a school year, because humanities is not something one grade owns. Anyone learning assessment can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Comparative Judgement poster?
- Consider it for open writing, where rubric marking is least reliable. A wall chart earns its place by being glanceable from where the work is happening, so Comparative Judgement belongs on the wall where that humanities work actually happens, within glancing distance, rather than filed away.
- What other posters go with Comparative Judgement?
- Reliability, Blueprinting A Test and Feedback That Works sit alongside Comparative Judgement in the Education section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.ReliabilityBlueprinting A TestFeedback That Works
- Is the Comparative Judgement poster free to download and print?
- Yes. Comparative Judgement downloads as a free PDF with no account, no email and no watermark, like everything else in the Education section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Comparative Judgement poster print at?
- Comparative Judgement is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Comparative Judgement loses nothing.Printing guide
