Success in exams has an important role to play in making children happy, the education secretary has claimed.
Michael Gove believes that doing well in tests can encourage children to learn more, as well as improving their wellbeing.
He is expected to tell the Independent Academies Association conference today that stricter testing is required in England's schools, with easy exams posing very little intrinsic value.
"Humans are hard-wired to seek out challenges," he is expected to say in an address titled In Praise of Tests. "Exams matter because motivation matters."
"If we know tests are rigorous and they require application to pass, then the experience of clearing a hurdle we once considered too high spurs us on to further endeavours and deeper learning."
For those in teaching jobs, the task will be to ensure that students are adequately prepared for their exams while ensuring that they are not just teaching to tests.
Mr Gove has made it one of his priorities to scrap the current GCSE system of exams in favour of the English Baccalaureate.
