Ofqual's reliability research

Research to investigate the reliability and validity of results in national tests, public examinations and other qualifications in England.

Reliability is a measure of the consistency of the results of qualifications and assessments. A reliable qualification would mean that a student would receive the same result if they took a different version of the exam, took the test on a different day, or if a different examiner had marked the paper.

See also Ofqual’s ‘Reliability of Assessment Compendium’ that pulls our comprehensive research into one list of documents.
