Russell Hobby, general secretary of school leaders' union NAHT said: “It emerged last night that the live test paper for the Key Stage One Grammar, Punctuation and Spelling (GPS) test has been available on the DfE website for several months and has been used by some schools as a practice paper. We have no way of knowing how extensively it has been used by schools and parents.
“We wrote to the Schools Minister Nick Gibb this morning, expressing our concerns and asking him to free schools from the obligation to use the test. In deciding to pull the tests for this year, the Minister has acted quickly and appropriately to address the issue. School leaders will welcome this approach.
"We reaffirm our offer to the government to work with them to develop a stable, coherent approach to assessment.”
