The Government recently updated its guidance on the status of EU nationals following the triggering of Article 50. The guidance, issued on 7 April 2017, is available as a new information page at GOV.UK and may be accessed here. The revised guidance replaces the statement issued in July 2016.
The unions (NUT, ATL and NAHT) have also received a reply to their letter to Justine Greening urging the Government to protect the status of EU teachers already in the UK. The letter to the Secretary of State and her reply may be found here.
