Not listed: independent practitioners. Practitioners are independent third parties, not a fixed list, so we do not name them here. We send you a shortlist and you choose whether to contact them. We do not send your information to a practitioner. You can give permission in advance to share your assessment answers and test results with a practitioner if you later go ahead with an introduction, and nothing is shared before then.
