Advanced Technology is a legal name, not really in the vocabulary of ordinary Scientologists. It refers to the works, usually issues, that comprise the levels labeled "confidential". This would include R6EW, the Clearing Course, OT I, OT II, OT III, New OT IV, New OT V, New OT VI, New OT VII, New OT VIII; also the original OT levels, currently withdrawn, of OT IV, OT V, OT VI, OT VII; L-10, L-11, L-12; also some Flag-only rundowns.

The name appears in IRS-related matters.
