The Commission for the Compact has commissioned consultants Rocket Science UK to analyse eight Government departments at a cost of around £16,000.
The departments, which include the Department of Health, Department for Work and Pensions and HM Revenue and Customs, were chosen on the recommendation of the Office of the Third Sector for being most important to charities.
The Commission for the Compact has chosen Friday, which is Sector Independence Day, to reveal some interim findings. The full report is due out in about a month.
Sector Independence Day is held each year on July 4 to promote the independence of the voluntary sector, which is enshrined in the Compact but frequently abused.
On the same day, Compact Voice will publish the results of separate research on what participants in a series of focus groups think about independence.
Saskia Daggett, Compact manager for Compact Voice and the NCVO, said it was "the first rigorous research into independence so far".
