CNC Training & Testing

For New Raters
While one person does the testing, 2, 3 or more observers rate each item independently. Afterwards discuss ratings. If a rating is changed, leave the initial rating but place changed rating in parenthesis next to it. Repeat this process on 5 to 10 patients or until raters train themselves to place patients in the same category range. Thereafter single ratings can be used but, for purposes of reliability, a minimum of two independent ratings per patient is encouraged.

Under "Comments" record special information that may have had an extraordinary effect on the ratings on a given day.
