David Cameron and Nick Clegg are set to publish a dossier detailing progress on hundreds of pledges made by the coalition government.
The document is expected to show that the vast majority of aims have been met but acknowledge some have been missed.
The Daily Telegraph predicted that it would be released on Wednesday.
The new dossier is understood to be an annexe to the coalition's Mid-Term Review, which was unveiled by the prime minister and his deputy on Monday.
Mr Clegg last month promised to publish a "candid" audit of the government's performance, but this did not feature in the Mid-Term Review.
However, it is understood a document detailing each of the 480 measures in the 2010 coalition agreement will be released to update voters on what progress has been made.
