The department's policy is to employ statistical disclosure controls to ensure that statistics including those collected for research purposes do not reveal the identity of an individual, or any private information relating to them, taking into account other relevant sources of information. These statistical disclosure controls protect against both specific known risks and more general risks including unknown risks.
The figures provided by Birmingham on the number of electively home educated children who were subject of a child protection plan are small and we are not releasing them for these reasons.
The department keeps its statistical disclosure controls under review to ensure that arrangements for confidentiality protection are sufficient to protect the privacy of individual information, but not so restrictive as to limit unduly the practical utility of the statistics.
We provided a frequency distribution histogram to assist users in understanding the range of data provided by different local authorities that can be found at http:www.dcsf.gov.uk/everychildmatters/ete/independentreviewofhomeeducation/irhomeeducation/.
