MTB (Music Teacher's Board) is a relative newcomer. Exams are recorded in video or audio and submitted through their app. So exams can be sat at home, when the candidate is ready with complete flexibility over the date. The list of pieces covers a broad range of styles and doesn't go out of date: new pieces may be added (bi-annually) but 'old' pieces remain as options.
