Technical employers including Ambassador Theatre Group, White Light, the Royal Opera House and the National Theatre run apprenticeship schemes, as do many regional theatres.
In most university technical theatre courses, everyone must work on several shows a year as part of their degree.
Students Jack Vertigan and Jessica Bowker, currently studying at St Mary’s, explain that for each show, they are assigned a skill, which changes per production.
Gabriel Hipperson is a former student at St Mary’s who started his course aged 18.
Two years later, he’s working as a flyman at the Lyric Theatre, after first doing two months general stage work at the venue.
The courses are also designed with input from employers, meaning that the skills you learn should be transferable to the workplace.
