''"testing" is only one form of assessment. If you really wanted to advance learning you would need to advance other forms which can often rely on teacher skill in observation,questioning and recording. You can't do this because national testing is about judging teachers and schools and therefore you cannot rely on the professional judgement of teachers as too much hinges on it for the schools and individuals. Instead you need to pursue the falsehood that there is some clean, discerning and fair national test, if only we can get the right people to develop one. It results in the nonsense of not allowing a pre published test to be used because the children would get the right answers- which is what you set out to achieve.'
