IGNORE MY LAST POST!!! You set me thinking so I rang up the LEA myself. Apparently, while it has been agreed to reduce the number of tests to 2, the content is by no means yet agreed. While the proposal was to have just VR and NVR apparently there has been a lot of pressure from parents for these to include elements of Maths and English. They are in discussions with NFER as to what format the 2 tests should take and hope to reach a decision "as early as possible" as they are getting lots of calls from parents of children in Year 5. The person I spoke to couldn't say definitely that the new tests would be set by NFER but as that is the body Bexley is in discussion with it would seem likely.
Any developments will be posted on the Council's website, but if you have a specific question, you could email direct on firstname.lastname@example.org
and they will respond to you.
