All experiments or explorations with genres, styles, media, materials, techniques, processes, and technologies should be recorded. Students who experiment with printmaking, sculpture, or painting techniques may find that photographic evidence (either digital or on film) provides enough clarity and detail for assessment purposes. Students who practise their instrument, produce installations, develop ideas for events, or rehearse a dramatic piece need to gather evidence in the form of audio/visual digital recordings so that they can select samples of their skills development for assessment.
