Tips for Additional Inclusions
To start with, include everything that you think may be relevant. You can prune things at a later date if your portfolio becomes unwieldy, but don’t lose the evidence. For material which you consider including but then reject, keep a supplementary file as this data may be needed in the future.
A portfolio is something akin to an information leaflet. Obviously, all the positive aspects of your experience should be in there, but there is no point in including non-relevant hobbies nor in over-selling your personal characteristics.
The portfolio demonstrates by its production values that you are literate and that you have an analytical capability, which allows you to organize material.
Other qualities, like enthusiasm, dedication and compassion, which are essential to a good nurse, should be demonstrated by the experience you have gained, and your reflection on that experience, rather than simply asserted.
