However, you cannot teach people to a level of accreditation. This means that people who attend sessions with you can have certificates of attendance but not certificates of accreditation. An NLP Trainer, like myself, is a person who has been through special training and who can provide certificates of accreditation to people, should they meet the criteria.
I can also accredit you to be an NLP Master practitioner which is the next level up. This is the highest level of NLP training and that allows you to accredit other people to be NLP trainers in which they can begin their journey in working with others to provide certificates of accreditation where they have met the criteria.
