Analysis: Are teacher assessed GCSE grades a good idea?

A  recent study has concluded that teacher assessments are as reliable as standardised tests in monitoring students’ performance.

The researchers found that both external Sats tests and teacher assessments were both equally accurate in determining later performance. This suggests teacher assessments are no more biased than standardised scores.

Exams are very costly to run and administer – schools could save precious resources through using staff assessments of their pupils instead to monitor progress.
While the research cited above shows teacher assessments can be as accurate as exams, this has not always been the case, especially when the stakes are higher.
