The article "Failure turns to success" (TES, May 29) goes a bit far in describing the Qualifications and Curriculum Authority as "the Office for Standards in Education's great rival".
QCA and Ofsted are both working with the Government in its drive to raise standards.
The important thing is that both types of evidence need to be considered - objective test and examination data, and classroom observations - when judgments are made about a school's quality. QCA is working closely with Ofsted to ensure that test and examination data are available to inspection teams to inform their overall judgments. This is not rivalry but partnership.
