Consider the scale below relating to task importance. Generally speaking,
what mean rating would use to call a task/competency "important"
(practically speaking, at what cutoff would you say it's OK to include the
task as an essential function on a job description, and/or target this
content for a written exam, assuming that the skills are needed upon entry
to the class and time spent performing task is adequate). 2.0? 2.33?
2.5? other? Why?

Also, if you were to say "In order to include the task, most incumbents
must perform the task", what % would you use to say "most" perform
it...51%? 67% 75%?
I realize there aren't hard/fast rules, and any 'cutoff' would be a
guideline...just wanted a reality check, thanks.

0 - Not Important / Not Performed - it is not necessary for an employee
to perform this or possess this competency to have acceptable performance
in this class;

1 - Somewhat Important - it is desirable, but not critical, for an
employee to perform this or possess this competency.

2 - Important - it is important for an employee to perform this or possess
this competency, and failure to possess this usually indicates an overall
performance problem.

3 - Very Important - not performing or possessing this would have a
negative effect on overall job performance; this is a major requirement
and reason that this job exists.

4 - Essential - it is extremely critical that the employee possess this
competency; failure to possess this competency would result in
unacceptable overall job performance.
