Cyfle trainee
From Tardis Wiki, the free Doctor Who reference
A Cyfle trainee is essentially an intern. They have been accepted on a course of practical study by Cyfle, the training company for the creative industries in Wales. This course usually, but not always, lasts for six months, and allows the participant a chance to work on BBC Wales productions. Cyfle trainees have worked on Doctor Who, Torchwood and several non-Doctor Who universe shows. Generally, the trainees have been seconded to the art department, and were therefore nominally under the supervision of production designer Edward Thomas.
