Carillion, Shepherd, Interserve and Wates are among the names supporting a free end-of-term concert for pupils at the O2 Arena.
The Transformation Trust – which is funded by private sector companies – will host the Rock Assembly on 20 July 2011 with support from several public and private sector bodies.
The Department for Business, Innovation and Skills is supporting the Transformation Trust’s University Village as part of the department’s campaign to explain fees and bursaries.
The New Schools Network is also supporting the event, as are Bell Pottinger Public Affairs, Gaia Technologies and Meru Networks.
Amy Leonard, chief executive of the Transformation Trust, said: “We wouldn’t be able to host events like Rock Assembly without the help of our supporters, and we are grateful to them for seeing Rock Assembly as an important event in the calendar that they are proud to be involved in.
“Rock Assembly for us is an opportunity to mark the end of term, and celebrate the achievements of the past academic year for pupils up and down the country, as well as for The Transformation Trust – which is going from strength to strength, providing extra-curricular activities and support for thousands of pupils and teachers over the coming year.”
