We had outstanding Ofsted too, but our parents said they were happy with levels of communication [sticks tongue out at Cod]
I think it is a middle-class thing though, and our catchment is very mixed, so we don't have so many mc families.
Our school does:
Beg. of yr each class sends home a letter with details of homework/swimming lessons/PE days and similar.
Beg. of each term they send home A5 leaflet (i.e. A4 folded - 5 sides) with details of the topics and curriculum for that class.
Regular whole school letters home, including all diary dates at beg. of the year. These letters are numbered, so if you've missed one you can get a copy.
Letters about trips, residentials, other activities always come in plenty of time and are administered well.
Parents' eves end of first half term, and just before Easter.
Full reports home end of summer term.
Open Door policy with all staff (end of day)
Regular special training for parents - e.g. what are SATs about, how to help your child with maths, child mental health issues, sessions with school nurse, etc.
Also regular invites to special events - fun run, leavers' assembly, plays, poetry workshop, etc. etc.
There is also a school website which is regularly updated and has copies of the letters.
Crikey! I'm exhausted just having typed all that list!
