The team behind plans for a new school in Stamford will put their case for funding to the Department for Education this month.
Ministers have invited representatives from the Stamford Free School bid to a formal interview on Monday, March 17.
Two members of the original proposer group, made up of Stamford parents, will be joined by three from the Cambridge Meridian Academies Trust.
Daniel Evans, who has been involved with the project from the beginning, said: “In past rounds only a small minority of applicants have been invited to interview so we are delighted to have made it through to the next stage of the process.”
Following the interview the Department for Education will make a final decision on whether or not to fund the proposed school.
There is still time to register support for the project at www.stamfordfreeschool.org.uk.
The proposer group has already done a mock interview with the New Schools Network, a charity that supports free school proposer groups.
The charity is also backing a joint bid by Catmose College and Uppingham Community College’s bid to create a new sixthform college named Harington School in Rutland.
The two schools will now be working with the network in to finalise the application which will be submitted to the Department of Education in May.
Catmose College principal Stuart Williams said: “I am thrilled as, with this news, Harington School is becoming a likelihood, rather than a possibility.
“The backing is a significant step towards having a successful academic sixthform provision for students who currently cannot afford the travel expenses or school fees that are necessary for them to access the provision they need.”
