Teenagers who work part-time for more than six hours a week do not do as well in exams as those who don’t have jobs, says a report by the Institute of Fiscal Studies, an economic think-tank. Using data from the National Child Development Study, which followed a sample of individuals born in one week in 1958, researchers found that 16-year-olds who worked did 25 per cent less well than their non-working counterparts.
