Prior Learning

The processes of assessing Prior Learning are commonly referred to as RPL, APL, RCC and may also include cross crediting or credit transfer in a formal education arrangements.

There is a range of methods that APL, RPL & RCC can be applied but essentially your existing knowledge and/or current competencies will be assessed after your training or experience has been acknowledged as being sufficient to demonstrate that tyou are ready for assessment.

Your Assessor may collect a wide range of current and diverse evidence to judge against the assessment requirements.

It may be more manageable for all parties if the candidiate was to complete a common assessment task or collect the evidence outlined in the approved assessment or evidence guides currently being used by the Assessor.
