The National Youth Theatre (NYT) is to hold free auditions in five cities and online next month February.
The auditions will take place in Birmingham, Bristol, Glasgow, London and Manchester. Online auditions are via the National Youth Theatre Hub.
Successful applicants will be invited to take part in summer intake courses, which for the first time will also take place in cities around the country.
Applications must be aged between 14 and 25 on the date the course starts. They will be asked to prepare a two-minute speech which could be from a published play, monologue book or film script.
The company will also offer be offering "backstage interviews" for young people interested in areas such as lighting, sound, stage management and costume.
NYT patron and alumnus Matt Smith said: "It's a great company and if you work hard, apply yourself and bring the right spirit, it's a place where you can really learn and develop, and a company that will nurture you."
