Assessment involves establishing how much an individual learner or group has learnt, and will involve both learners and tutors/assessors. In some cases the process begins before the course starts and continues until after it has finished.
Learning is a change in skill and/or attitude and/or knowledge and measuring these changes are the steps in the assessment process. Assessment is the judgement of evidence showing that learning has taken place (an act of measurement) and confirming that a learning outcome, or part of a learning outcome, has been achieved.
