This is the third OGN in the assessment series. It covers issues to be taken into account when conducting an assessment. The approach should not be prescribed, but developed in line with the specific context and purpose of each assessment. This OGN does not set out a series of detailed steps or lists of questions to ask, but instead provides direction on good practice approaches and ideas on how to undertake different aspects of the assessment. You should use this as guidance when determining the specific methodology for your assessment.
