The Sharing Education Programme (SEP), which has funded 12 projects working in 60 Catholic and Protestant schools in Northern Ireland, is in the process of selecting its second cohort of projects.
Teachers on the residential course will explore the issues that have arisen since SEP's launch in 2007 and look at how to get schools involved in future collaborative projects.
Researchers from Queen's University's School of Education will spend a few months working with teachers and developing their bids before a final group of 10-12 projects is chosen in January.
Limavady High School, a specialist in performing arts, has worked with eight other schools in the Roe Valley on an SEP project over the last two years.
Limavady High School principal Glenn Reilly said: "It gave us an impetus to address the prejudices that we all hold, in a way that wasn't in the young people's faces, but was just part and parcel of how they did things."
Up to pound;2.8 million will be made available for the schools and classes will begin in September 2010.
