Learners and new practitioners often confuse these two roles. They are related but distinct, and understanding the difference is essential for anyone working in accredited training.
What an assessor does
The assessor works directly with the learner. They judge evidence — observations, PoEs, tests, workplace outputs — against the outcomes of a qualification and decide competent or not yet competent, with feedback for re-assessment where needed.
What a moderator does
The moderator never assesses the learner. Instead they check the assessor's work: were the instruments valid, was the judgment fair and consistent, is the evidence sufficient? They sample decisions and compile a moderation report that either confirms results or sends them back.
Why they must be different people
Independence is the whole point of moderation. If the assessor also moderated their own decisions, there would be no real quality check. That is why structures require separate registrations and separate people.

Frequently Asked Questions
Which should I become first?
Assessor. It is the prerequisite for moderation in most fields, and it is where most of the available work sits.
Can one person be registered as both?
Yes — just not on the same learners at the same time. Holding both widens the contracts you can take.
