The   CID Register of Members 

Only institutions or individuals listed in the CID Register of Members can use the title of 
Member of the International Dance Council CID    after their name.

You can also check if someone is a Member of the CID by searching the Global Dance Directory 
For an institution (dance school, company, federation, association) type one or two words from its title.
For an individual person type his/her family name.
If you are not sure of the correct spelling type other keywords, such as street or locality and dance genre (ballet, ballroom, belly, Indian…).
If you get too many replies try another spelling or another combination of keywords.
