Primary, we turned up waited to see teacher, went in on our turn - always a bit late but hey-ho.
Secondary, Y7 we made 10min appointments to see all the teachers with 10 min in between each in case of overrun - everything ran late complete chaos, we saw almost everyone in the end, but my god so stressful.
And it turned into a "doing well, on the right track, good attitude, keep it up" fest...
Y8 onwards - emailed teachers - "do we need to come to parents evening?" "Doing well, so not unless child is unhappy or you have something you want to raise" - No... Thank you....
Haven't been to one since. Good school, great teachers, clever self-motivated kids (YES I know we are lucky on ALL counts) DDs both still top groups, doing well, no discipline problems, both prefects etc... I don't need to be told they are doing well - I know and can see it.
