Who is the Checking What Works poster for?
Checking What Works belongs to the Criminal Justice section rather than to a school year, because law & society is not something one grade owns. Anyone learning policy & evidence can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Checking What Works poster?
Use it before repeating any statement that a policy has been proven to work. A wall chart earns its place by being glanceable from where the work is happening, so Checking What Works belongs on the wall where that law & society work actually happens, within glancing distance, rather than filed away.

Is the Checking What Works poster free to download and print?
Yes. Checking What Works downloads as a free PDF with no account, no email and no watermark, like everything else in the Criminal Justice 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 Checking What Works poster print at?
Checking What Works 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 Checking What Works loses nothing.Printing guide
