I was a School Governor for eight years.
For a while, it was my job to get up close and personal with stats to do with Progress, Value Added (ugh...) and SATS (double Ugh... damn Labour gubbinsment).
Two things stood out in that time.
(1) The funding was generally adequate, but often wasted because we (Middle School) had no idea how much was coming, for what, and when. Admin was overly complex and provision piecemeal.
(2) The parental support was mixed at best, and in some years completely shameful.
We (Chris and Mrs S) brought our own children up to the best of our abilities. We read to them, listened to them when they talked about stuff, and treated them like people. We were lucky that we could give them opportunities, like learning musical instruments and stuff, that our beloved LEA had already largely pulled from schools.
In my years as a Governor, I was scared sh*tless by the number of kids who didn't have that secure grounding. That's not meant to beat my parental drum - I basically just followed what my parents did, but so many kids came through the school who:
1. Had multiple sets of parents
2. Had no access to parental time in the evenings
3. Treated school as an escape
4. Were essentially disfunctional - as in, at the age of 7, couldn't dress themselves or use a bathroom unattended.
It comes as no surprise to me that secondary schools have trouble making sense of that
