Yes they can sit the test at their school IF the school agree to it, but if they subsequently refuse to test at the school, you will have to pay the courier costs. The other option is take the test during half term at a venue arranged by County.....follows a copy and paste from last years admissions booklet. I had a child in this position a few years ago. I am not aware that it has changed.
If you wish your child to be tested at an out area
school and you state on our form that the school
has agreed to test, if they subsequently refuse we
will ask you to refund the courier costs of issuing
and returning the test papers.
Otherwise, children can take the tests on two
separate days during October half-term at a venue
we arrange. It is very important that children who
are not to be tested in a Buckinghamshire school
register for the procedure early, and at the latest by
8 September 2006. If you do not do this, there may
be long delays in testing, and, if your child
qualifies, there would be limited places in the grammar
Have you registered, have you asked your school if they will test, what did County say? I am assuming that your school is out of County.
