We convert your slider ratings into three straight-forward categories:
1 to 3.9 - Needs Improvement
4 to 6 - Meets Expectations
6.1 to 7 - Exceeds Expectations
Nonumbers on the slider is intentional. Itwill help you think clearer about judging each task independently. Think aboutthe employee’s performance over the entire review period, not just last week.
Research supports the 7-point scale
JuvodHRuses a 7-point scale because research shows it’s highly reliable withmeaningful point intervals.A 7-point scale allows specificity in ratings without providing so many optionsthat it’s confusing.
