I think teachers with nothing to cover up will have nothing to fear from supplying back ground checks like Enhanced CRB/DBS certificates. https://www.gov.uk/government/organisations/disclosure-and-barring-service/about

In fact I think that a clear CRB/DEBS should be an integral part of any visa application and that the Enhanced CRB/DBS should only be at maximum three months old, therefore I think that there should be a change in UK too to allow private citizens to apply for the Enhanced DBS. Perhaps the UK DBS Agency could also create "Supplemental DBS Certificates" every six months and that ALL UK teachers should have these as part of their membership of the IFS

Next suggestion would be for overseas authorities to only accept UK teachers with DTLLS http://www.cityandguilds.com/Courses-and-Qualifications/learning/teaching/7305-teaching-in-the-lifelong-learning-sector-dtlls coupled with membership of the IFS http://www.ifslearning.ac.uk/

Closure of all Teacher Recruitment Agencies and TEFL/TESOL certificate mills would also be considered.

I found the statements on page 2 of the link rather telling about Chinese Agencies, perhaps the authorities there will begin to wake up now.

And if chummy has done anything over there then I hope that Chinese Plod have the first, because that won't be much fun.
