Depends what organization you sign up but Nesba let you pass on straight away(novice) and STT does let you loose/Pass on the last 2 sessions of the day just to get the feel of how intermediate works.

Most track days are split in to three groups here in the U.S.

Novice = No passing.
Intermediate = Passing on the outside only.
Expert = Anything goes.
