It depends on whether you wish to teach our material or simply teach the basics of MTDISC.
If you wish to train your team/organization using our Effective Communicator training, which relies on MTDISC, you will require a license. Email us to find out more.
If you are simply going to provide the instrument to your team members and go over it with them, you will not need a license. You can find a free podcast with guidance on how to do that here.
