The Standards and Testing Agency (STA), an executive agency of the Department for Education, is now responsible for the development and delivery of all statutory assessments from early years to the end of key stage 3. This work was previously carried out by the Qualifications and Curriculum Development Agency, which ceased its final remaining functions in March 2012.

If you would like more information on national curriculum assessments and the work we do, please see the assessment section of our website.
