A portfolio is a purposeful collection of a student's work in an area, showing growth, self-reflection and achievement over time.

It gathers evidence of the learner's development rather than a single test score.

Positive practice is a behaviour-correction method of repeatedly performing the correct response.

Personal development refers broadly to the growth of the individual, not to a collection of work.

An anecdotal record is a short, factual note of a single observed incident of behaviour.

Portfolios support authentic assessment by making learning visible through actual products.
