The move from standardised testing of 11-year-olds in Wales to teacher assessments has led to inaccurate and unreliable results, according to the inspectorate Estyn. Sats for 11- and 14-year-olds were abolished in Wales in 2005 and inspections show that a quarter of schools inspected each year have “shortcomings” in some aspects of their assessment. The Welsh Assembly Government has announced a pilot scheme to externally moderate marks given to Year 6 pupils.
