That questionnaire is valueless because it does not address the subjects behaviors as compared to "normal" human behaviors. ie.: "careless" compared to what?
Then there is a reliance on ONE persons opinion.
For example there are people who are highly numerate, display rigid personalities and have zero tolerance for mistakes. To them anything but absolute accuracy and timeliness from students is "careless, disorganised work". This begs the question: "what about the sanity of the instructor?" as discussed in the referenced thread right now?
Instructors with attitude problems
A look at the FAA entry on the subject shows that it s a complex matter and not something amenable to cheap self suggesting questionnaires.
