Prof. Portfolio

Ive been slacking since graduation and haven’t touched my portfolio. Now I am finally about to start working on it again. Now my question is…How does a prof. folio differ from a students? Are there some guidelines I should follow? Are there now different things I should try to showcase? Is there a different look to a prof. folio as far as layouts and such? Another question I have been thinking about is, Should my folio take on this new look/layout where you can see the jump between school and prof.? Kind of like a transition into the real world? or should I have the whole folio in the same format? Also as time goes on, when does the student work start to get the boot? I am not working mainly in housewares and I dont want to have a folio full of the same type of work.
