It depends....
If you are planning on joining any of teh Certification Boards as a Verified member you will need to demonstrate that you have been taught by an approved institute such as mine
The iGNLP™ etc will require you to submit a copy of your training Certificate of Completion to obtain Verified status.
You can skip getting our Certificate if you want to however on the iGNLP members profile pages your verification will show as 'pending'
The Certificate looks great though and is verifyable online. and when you consider the benefits of having it you might conclude that it is a worthwhile investment. You can get your Headgearlabs Certificate free by clicking here https://u812.co/hglassocnlpprac
