A dance-school show can involve several classes, costumes and rehearsal sessions for each performer. An app could give families a personalised view of what applies to their child without revealing the whole school's private records.
Participation approval should drive rehearsal invitations and costume requirements. Costume sizes, payment status and collection need separate records. Staff require a way to correct allocations without sending confusing updates to unrelated families.
Pilot one production and test a pupil in several dances, a changed rehearsal and a returned costume. Protect private notes and limit children's information to authorised users. A useful first release would clarify confirmed commitments and current instructions, with staff retaining responsibility for supervision and backstage arrangements.
