Staff - How is the service and helpfulness of the doctor's staff? (This category is NOT included in the "Overall Quality" rating.)
Punctuality - How long does the doctor keep you waiting? (This category is NOT included in the "Overall Quality" rating.)
Helpfulness - This category rates the doctor's helpfulness and approachability. Is the doctor approachable and nice? Is he rude, arrogant, or just plain mean? Does he have a good bed-side manner?
Knowledge - This is the most important of the three categories, at least to most people. How did his treatments work for you?
The Overall Quality rating is the average of a doctor's Helpfulness and Knowledge ratings, and is what determines the type of "smiley face" that the Doctor receives. Due to popular demand, a doctor's Punctuality and Staff ratings are NOT used when computing the Overall Quality rating.
