AN occupational psychologist has been credited with helping transform a school’s exam results.

Dr Chintha Dissanayake of Oxford Psychometrics ran a staff talent development programme at Pembrokeshire school Ysgol Dewi Sant, which narrowly escaped closure in 2015.

Headteacher David Haynes described this year’s GCSE and A-level results as ‘record breaking’.

Dr Dissanayake’s past clients include the United Nations, the Cabinet Office, the Civil Aviation Authority and Barclays Bank.

Before that, she was a prison psychologist for the Home Office, working with young offenders.
