My DC's school is a state primary (England). We have 2 parents evenings a year, one around Nov and one around March. We are free to make appointments with the teachers as necessary in between, but if you do that too often you feel as though you are being pushy.
Going from March to November without a parents evening feels like a very big gap to me, I would ideally like a third one after reports come out but they don't come out till the very end of summer term, just wondered what happens in other schools.
