Nearly nine out of 10 pupils in England feel pressure to do well in SATs tests at the end of primary school, according to a poll for the BBC.
BBC Newsround commissioned the polling company ComRes to interview 750 10- and 11-year-olds who will be taking Key Stage Two Sats tests this week.
More than half (59%) said they felt some pressure to do well while (28%) felt "a lot of pressure".
In the survey carried out last month, children were asked to pick a variety of words describing their mood in the run-up to the tests and 59% said they were nervous, while 39%, told researchers they were worried.
But most were not unduly distressed, with almost half (48%) saying they did not mind taking the tests and an additional 14% saying they enjoyed them.
The survey follows moves by some parents to keep children off school in a day of protest about primary tests in England and more than 40,000 signed a petition calling for a boycott of the tests.
