The philosophy is that you are intelligent adults who can make your own decisions. You will be asked the extent to which you want assignments to complete independently. Those that do more work on their own usually have better outcomes. At the same time, some clients prefer to do the assignments in sessions. That is fine too, know that it will cost you more and take more sessions. Clients who want to be held accountable will be held responsible for outside work (but let's face it, only so much can be done in this regard). Clients who want to be left alone can be left more alone outside work accountability. Homework doesn't have grades, and the only person that can ensure it gets completed is you.
