Thanks, Gert12, for your succinct and honest reply. Much appreciated (the cold wind whistling through Mumsnet was a bit disconcerting....). I'm impressed by the Head of Governors at Cheam, who ultimately took responsibility and made a decision that required both courage and conviction.
Good to know that 'a certain person' FINALLY got his comeuppance..
I am flabbergasted (despite having worked in the IAPS world for many years) at how many inefficient Heads are appointed in prep schools. It does seem that having a few impressive schools on the CV, having 'the gift of the gab' and riding on the back of an excellent inspection at a previous school is the key to the door - despite the fact that the Head-to-be in question may have played no part in the successful inspection: perhaps delegating everything while playing Candy Crush on their phone or watching the cricket!
Being white, heterosexual, preferably male and preferably privately educated does also seem to be a key factor in IAPS/ ISC world (Yawn!). Ie 'looks the part'. Come on IAPS/ISC - show me a black gay couple (preferably with a cat) who are co-Heads, and I will eat my hat! (I'd better buy an edible one, just in case..).
They do say that in all fields of industry, those who get to the top of the ladder either get there because they're exceptional 'people's people': kind and thoughtful souls who sincerely care about their staff, and thus the success of their tenure is down to a happy and therefore positive, loyal and efficient staff body; or ruthless, ego-maniacal shysters who have got there (and their 'results') at other people's expense, and with many a casualty on the way ( ie more gentle souls who've been pushed off the greasy pole and whose careers have thereafter been adversely affected). Speaking from direct experience here of CEOs//Heads in the fields of journalism and education.
In my years as a teacher (both prep and senior), I've only ever worked for one person whom I consider to be an exceptional Head. Kind, bright, witty and courageous (not a 'yes man' to the parents and Governors - a rare thing today), his motto is 'staff first', which would be unheard of, I fear, in today's world in which independent schools are run like businesses (sad this, as his 'reign' only ended nine years ago...).
This particular Head cared deeply about the wellbeing of his staff and had the intelligence to know that a school (and its wafer-thin reputation) is only as 'good' as its staff. He also realised that treating staff like sh*t , and/or like wheels on a machine is ridiculously shortsighted - and, ultimately, very expensive. (Oh dear! - another wheel's fallen off! Never mind - we can get another, cheaper one. Doesn't really matter, it's just an old wheel...).
Given the new Government's abolition of VAT exemption in independent schools, soon to kick in and take its toll, these next few months and years will be crucial for all schools in the independent sector - and it's the small, less-thriving prep schools who are in the most danger. Having the right Head in place will be crucial.
I hope that a few Heads and Governors read this post, which is an honest opinion from someone who's worked in the independent sector for a long time. And who cares about the future of the nation's schools.
