The reliability criteria should be applied by following the four tests that enable you to make a consistent decision.

Where an individual does not meet each of the reliability criteria for a specific descriptor then you must consider an alternative descriptor for that activity.

• Repeatedly; and
• Within a reasonable time period;

Each test is explored in more detail below.
