EYFS, which comes into force in September next year, has already been harshly criticised by teachers, parents and politicians.
At the time of its launch Margaret Morrissey, from the National Confederation of Parent Teacher Associations, said: "I think it's really sad that we have reached the point now where instead of reducing children's stress we have increased it.
"Will nurseries be worrying more about children reaching these targets than caring for our children?"
EYFS applies to around 25,000 nurseries across both private and state sectors, plus all childminders.
