iTAT is a development of TAT, based on some of the basic TAT principles, but it is a quite different therapy to TAT. It was developed in the United Kingdom independently of the original TAT therapy and is a separate therapy. It has more similarities with BSFF
It is taught usually as part of an Energy Therapy workshop. A training in iTAT does not constitute a TAT Practitioner qualification, as the latter can only be obtained via TATLife.
