"....Don't forget, for you to have 1 parent's evening a year, that means the teaching staff have 7 over the year, not counting options evenings, open evenings, meetings about trips and extra curricular activities, concerts, plays etc. Some of them might want to see their own families occasionally."
Sorry, but that one doesn't wash. If you choose to be a teacher, you wear those evening meetings the same way as I, as a parent, support your 13 weeks or so annual leave. One trades one against the other. I, and many other parents am away from my family from 8 til 5.30 five days a week, 46 weeks a year. And am on call a quarter of my other waking hours. It's my job. And should you need a non urgent but important medical appointment, do you forgo your desire to attend that- 'because the medical people have families they'd like to see occasionally' as well? Quite.
I am not requesting 2 parents evenings every year, just maybe in Y7. FWIW, I have never set eyes on DS1's form tutor, who in theory will be my son's mentor and guide for the next- well, four years of his education, now! The 'settling in' parents eve was 'meet the subject teachers'- after DS had been there 6 odd weeks! Others here seem to have had a meeting with the tutor after the first half term then a full-blown parents evening around now.
And as for phoning the tutor or emailing them- not at our school you don't!
