The message will be sent out this month, in the same envelope as letters trumpeting a rise in child benefit due next spring - hopefully, linking the issues in parents' minds.
However, plans to cut benefits for parents of truants have been dropped. Critics said that writing to all parents - the vast majority of whose children do attend school - was a waste of time and money. Ministers were accused of a 'face-saving' exercise to salvage the ghost of Downing Street's idea.
The leaflet from the Department for Education and Skills will go to all parents, even those of under-fives. It will include information on childcare. 'It is about rights and responsibilities. If they get that message, then that is a good thing', said a DfES official.
