If you feel that you can demonstrate and evidence learning of an appropriate standard and volume, you can be assessed in relation to the learning outcomes of a module or programme. You will study independently to do this, but will have the guidance of an APEL Tutor and/or Subject Specialist.
You will need to identify the learning which you are claiming to have achieved and prepare a portfolio of evidence to evidence that. It is usual for this to involve some sort of reflective writing about your learning but it might involve many other forms of evidence too, even artefacts such as art work.
It is important to remember that it is the learning from experience rather than the learning itself that is assessed for credit and so you will need to be able to articulate this.
