Phew, I was thinking that an extensive critique of the Impact Assessment for the EHE component of the Children, Schools and Families Bill was called for and thankfully, here it is.
"Overall there seems little doubt that the proposed options for registering and monitoring...will incur at best a very small net quantifiable gain. Given the potential numbers of EHE children it is more likely that the proposals will produce a net ten year lifetime loss."
And this is putting aside all those other key questions about how one actually judges the nature of a suitable education.
There's another more forthright critique of the IA here.
