Wakefield pupils are being asked to create their own poems or pictures about Sats in a competition to be judged by Alan Gibbons, a children's author.
Local branches of the NUT and National Association of Head Teachers are organising the event as part of their campaign against the tests, ready for a national boycott of Sats next year.
Mr Gibbons is founder of the Authors Against Sats campaign and will speak at a public meeting in Wakefield on Thursday, when the competition will be judged.
Asked if they would be prepared to accept entries from pupils in favour of the tests, Barbara Murgatroyd, NAHT assistant branch secretary, said: "I would love to see them, but I would be very surprised if there were any."
She said early entries included poems about how distressed Sats made children feel.
Pupils' work should be sent to Wakefield NUT co Snapethorpe Primary School, St George's Rd, Lupset, Wakefield WF2 8AA, or emailed to firstname.lastname@example.org. Entries should include the pupil's name, school and age. ws.
