Name and where I can usually find key personnel - safeguarding team, head, secretary. Photos of them ideally.
TAs attached to each class (if this is the case.) 1:1, specific interventions or general TA?
Daily timetable clearly showing breaktimes, assembly time, lunch. The exact order of lessons will be different for each class, but you could still fill in as Lesson 1, Lesson 2, BREAK and so on.
Plan of the building, with fire meeting point clearly highlighted. I would want each classroom to modify their copy slightly so their class is outlined in a colour to help orientate. Lunch hall and staffroom equally clearly marked.
Any marking requirements eg marking codes if used, coloured highlighters, which colour pen used by children to edit vs used by teachers to mark. Is there a specific code to use to indicate work done by a supply teacher?
Presentation policy - ch write in pen or pencil? Print, cursive, continuous cursive? How work is laid out in books- date then title or vice versa, long date or short date ,WALT vs LO vs general title?
Photocopying code if needed at your school - we have a "Guest / Visitor" code. Location of copier! Also where spare paper can be found when it inevitably runs out with three copies left to print.
Info about staffroom - whether it's a free for all on the cup front, or if Mrs Jones gets sparky when a supply teacher accidentally uses "her" cup and so you have school branded ones for visitors (obviously you wouldn't explain about Mrs Jones, just about the branded cups!)
