I’d advise continue with good associate program, summer schools, intensive courses instead of a yr 8 place at vocational school, audition at 16 for upper schools, from experience my dd who attended vocational school at 11 was at no more of an advantage at auditions at 16 then others who attended local dance schools/associate schemes. I’d say if your dd wants to audition for the experience that’s great, vocational lower schools do not always offer the ‘best’ training compared to intensive courses, competition experiences, summer schools etc. Good luck to your dd whatever she decides
