The Global Skill Development Council doesn't only provide the candidates with a certification, but they maintain a Member Directory of all the candidates who have been certified so far.
It is basically an easily accessible in-built database of the candidates. Once your certification is done, your name will be automatically added to the database.
If you are applying for a new job and the HR needs to do some background verification, all they need to do is to put your name and the level of certification you have completed in the boxes below. GSD Council will help them out with all your details afterward.
