  • All categories must be scored: it does not matter which research design was used
    • The lowest score for a category is 0, the highest score is 5
    • Category scores are whole numbers only (that is 0, 1, 2, 3, 4, or 5)
    • The score for each category must be reported
    • The total score (out of 40 or as a percent) is reported in addition to each category score.
  • Item descriptors may be marked present (✔), absent (✘), or not applicable (◼).
    • Tick marks are not a check list to be totalled.
    • Tick marks are simply a guide to scoring a category.
  • If in doubt use your best judgement, there is no right or wrong answer.
