Literacy experts have warned the Government's controversial new reading test for six-year-olds is "costly, time-consuming and unnecessary".
It labels good readers as failures and risks holding some youngsters back, the UK Literacy Association (UKLA) said of the the compulsory phonics check.
Evidence shows the test is not appropriate for all children and the UKLA recommended that in future, rather than being mandatory for all youngsters, it is used at a teacher's discretion.
The new phonics check was taken by pupils across England for the first time this year.
It was introduced by ministers concerned that youngsters with poor reading skills were slipping through the net.
