Well Nick Whitfield said that the two challenges he had set himself when he took on the job were to deliver sixth forms and a Catholic School in the borough, so presumably he would view those as his main achievements. Though I would agree with you mum that the work he is doing with children's services is to be applauded.
However he is also proud of having prioritised optimising budgets over providing the spare capacity that the audit commission regard as essential to ensuring parents are offered a satisfactory level of school place provision. That is not common to all Councils, in fact is virtually unique, and is something that has become institutionalised over many years in the planning of school places and has disadvantaged many parents in the borough. To be fair it was going on long before the current administration though.
I would say that some of the achievements you list are also down to some outstanding school teams, particularly inspirational Heads like Maggie Bailey and it is good that the sharing of their strengths, expertise and best practise in borough schools has been facilitated.
I would also add the provision for children with special needs, the Catholic School has at least delivered benefit in terms of the new site and facilities in return for it's privilege, and the Council should be recognised for negotiating that as well as at least the 10 community places in the Primary School. Although provision nationally is shameful parents in this borough with children with significant physical, neurological or educational needs do have more provision in this borough than in most others.
I am glad we are focusing on something other than making the Turing House team the scapegoat for the political situation they find themselves in with relation to site.
