A teacher tricked his Year 6 pupils into believing they were sitting a science test before taking them on a surprise trip to Chessington.
Students at St Andrews C of E Primary School in Nuthurst, West Sussex, thought they were about to an exam, after a week already spent sitting SATs.
But when they turned over the test paper, it revealed that their teacher Sam Bacon, the school's deputy-head, had "tricked" them and was instead taking them to the theme park.
The test paper handed out by Mr Bacon read: "Chichester class Year 6 children are going on a trip to Chessington World of Adventures today and have been tricked by Mr Bacon into thinking they have a Science test.
"DO NOT MAKE NOISE - LET EVERYONE READ THIS QUESTION! LET'S GO ON SOME ROLLERCOASTERS!!!!!"
The teacher had secretly approached parents to obtain their permission for the trip.
Mr Bacon told the Standard: "At the end of SATs week, we normally do a treat like playing rounders on the Friday.
"But they've all been working so hard, so I thought I'd try and do something extra special."
He said he was delighted to watch the pupils read the paper in silence before turning to each other in disbelief.
"They managed to stay quiet until I said, 'let's go on some rollercoasters' and they erupted. There were quite a few tears," he added.
Other teachers were waiting around the corner to secretly watch the students' reaction.
They then packed off on the 45-minute journey to Chessington where queues were minimal due to it being a school day.
"It's a fantastic, small school so I got a lot of support from teachers," said Mr Bacon.
"Everybody knows how hard the students are working and that they are under some stress, even though as a school we tell them it's about just doing their best."
He added that they wouldn't remember the test "when they are 21" - "but will hopefully remember the trip."
