Our terms (prep school) are generally 10 weeks long, up to 12 weeks. We work every other Sat morning but it's activities we have to do not lessons. We have to cover in free periods if necessary. Our days are longer though, have to be in classrooms at 8.15am for registration to start at 8.30am, children leave at 5.30pm after compulsory prep at school. 18months ago I worked in a state school, I can honestly say that I am more tired during term time now as we squeeze so much in, but that the stress/pressure is far less. But longer holidays make up for that, we just had 3.5weeks for Easter, the children had 4 weeks, but we have 3 INSET days before the start of each term. No meetings during term time though, they are all done on the INSET days.
