. "Society hasn't really caught up with the fact that people retire when they're at the height of their powers these days. There's such a lot of energy, imagination and capacity for work left after most retirement ages."
She's not wrong. Setting aside the issues thrown up about qualified teacher status (experience, however extensive, doesn't always compensate for a full and rounded training programme), this idea does bring into sharp focus the talent that often lies dormant between retirement and, well, the Pearly Gates.
One cannot help but think that the deep understanding exhibited by Lady Warnock and Mr Jarvis - both of whom have been involved with educational lawmaking for more years than is decent to mention - is just what was needed when this week's education bill was being drafted.
The main aim of the bill is to target 1,000 so-called "failing" schools (and many more that are "coasting") with academisation - a process that will no doubt aggravate the already dire headteacher-supply crisis. As for the rest of the bill's contents, most teachers will probably take a look, shrug and say to themselves, as many did on Twitter, "Seen it all before."
And therein lies the problem: our schools system is exhausted from change. Lady Warnock and Mr Jarvis would not need it pointing out to them that between 1944 and 1978 there were just two major education acts. In the years since there have been 13.
Perhaps we should call for the creation of a crack team of creaking educationalists (Sir Tim Brighouse and Sir Mike Tomlinson are other contenders, if they're not too young) who would be consulted whenever a politician decides that what's needed is yet more legislation. This might just help to end the incessant reinvention of the educational wheel.
One can but dream.
