methyl, whatever the schools do will be ineffective. at the school near me, it had become the practice for parents to drive into the school yard, along an entry-way which is single track and doubles as the pedestrian entrance (the other entrance was sealed because it afforded dog walkers access to the playing field). this was clearly hazardous to the children so the decision was taken to close the gate to traffic. all this meant was that the parents then had to open the gates themselves. so the school started locking the gate. after the gates were vandalised several times to render them inoperative, and were expensively repaired each time, the parents began to realise they weren't going to win. the result was a free for all in the road outside, and frequent shouting matches due to parking rage, notwithstanding the yelow lines, hatching - and the regular attendance of the local PCSO. as a compromise the school negotiated a deal with the church nearby to use their car park, but the parents refused to use it as it was 100m away and it was "too dangerous for kids to walk to school".
so the situation persists. nightmare.
