The Hazlitt Theatre is home to the Hazlitt Youth Theatre (HYT), who have performed a "string of hit shows including pantomime, musicals, new writing, partnership projects, touring shows and a whole lot more!" The HYT provides opportunities for young people aged between 6 and 18 to put on productions, and to go and see professional plays. Being in a theatre such as The Hazlitt allows members to gain experience of all areas of theatre, and many members go on to study theatre-related courses at universities around the country. The Youth Theatre's most recent production was Working the musical by Stephen Schwartz and Nina Faso. It was well received by the audience.
