NCH was founded in 2011 by Grayling, along with internationally renowned academics including professors Richard Dawkins, Sir Christopher Ricks, Dr Catherine Brown and TV historian Dr Suzannah Lipscomb.
The college offers an arts-inspired curriculum.
Tin Man has been briefed to increase awareness of the college and its offering for students. The agency will initially work on a specific campaign in the lead-up to NCH’s first graduation this September.
Mandy Sharp, founder of Tin Man, said: "Since its launch three years ago, NCH has earned its reputation as a world-class academic institution that is leading the way in UK higher education. We felt the students themselves were fantastic advocates for NCH and our approach to this first brief was to celebrate their achievements in a truly innovative way, delivering a culturally engaging and newsworthy campaign."
Jenny Prytherch, PR manager at NCH, said: "The Tin Man team takes an impressively creative approach to briefs, which promises to bring the unique NCH experience to life."
