Sovereign Capital, which owns all five sites in Brighton, Bristol, Dublin, London and Manchester, has appointed financial advisory group Rothschild to conduct a review of the business and oversee the sale.
The company is already thought to have received interest from existing educational establishments and private equity firms.
Sovereign Capital bought a majority stake in BIMM in 2010 and has grown student numbers from 1,150 to 3,400.
Earlier this year, five music business and songwriting students who were sponsored by PRS for Music graduated from BIMM's Brighton establishment. They join previous alumni including Tom Odell and The Kooks.
