Established on 25 July 1904, it is now a registered educational charity. The ISTD provides training in a range of dance styles, with examination syllabi for students, and training courses for people wishing to become certified dance teachers.

Its main work is divided into two boards, one for Theatre dance (including ballet), and one for Ballroom dance (including Latin American dance).
