Frequently asked questions
Is this PPA and directed time calculator free to use?
Yes. It's completely free, needs no account, and nothing you type into it is saved or sent anywhere: it runs entirely in your browser and starts fresh on every visit.
What is the statutory minimum PPA time for teachers?
Under the STPCD, every teacher's timetable must include planning, preparation and assessment (PPA) time of at least 10% of their timetabled teaching time, allocated in blocks of no less than half an hour (paragraph 52.5).
What counts towards the 1,265-hour directed time limit?
Directed time covers teaching, PPA, duties, meetings and briefings, cover, and parents' or open evenings: anything your school directs you to do. Paragraphs 51.5 and 51.6 of the STPCD cap it at 1,265 hours a year, pro-rata for part-time contracts, and paragraph 52.4 requires any individual demand on that time to be reasonable.
Where do these figures come from?
The School Teachers' Pay and Conditions Document (STPCD) 2025: paragraph 52.5 for the 10% PPA minimum and paragraphs 51.5 to 51.6 for the 1,265-hour directed time limit. This calculator is a general guide rather than legal advice; your union or HR team can confirm how it applies to your contract.
