It's very difficult and there are lots of conflicting priorities.
We want data about what constitutes a 'good' school yet we don't want the activities that generate that data.
We want discipline for our children but not the boundaries that create it.
We want standards but at the cost of the creativity that delivers excellent education.
We want discipline but without the monitoring, behaviour management and imposition of routines that create this.
We want excellent attendance figures but not the management of attendance that goes with it.
We want our children safeguarded but we don't want the administrative burden that achieves this.
We want an individualised education without the cost.
We want creative teachers but not the lack of consistency that this can lead to.
We want a school that has great behaviour but we don't want our child sanctioned.
We want everything, everywhere, to be above average.
We undervalue the professional skill of teachers.
We actually undervalue the professional skill of school managers (often former teachers... so often poor managers and a teacher effectively lost to the profession to boot).
Basically we all want the best of everything available to every family at all times whether or not they engage with it.
