Ranking floor
The ranking compares units, teachers, courses or classes by an indicator. The ranking floor is the minimum number of evaluations a row needs to enter the classification.
Do not confuse it with the anonymity floor
They are two different floors, and both apply together:
- The anonymity floor protects the respondent. It is an institution rule and makes the number not exist.
- The ranking floor protects the comparison. It is your choice on this screen, and a row below it stays visible — it only leaves the classification.
Anonymity comes first: a row hidden by it does not appear even in the insufficient-sample band, because it was not read.
What the floor solves
With few evaluations, an average swings a lot. A teacher with 2 excellent evaluations can reach the top, ahead of someone with 80 consistent ones — and that number may feed an award.
That is why rows below the floor go to the "insufficient sample" band, with their number of evaluations alongside.
Recommendation and the effect of turning it off
The recommended value is 10 evaluations. When the floor is off, every row enters the classification, and the position of those with few evaluations stops meaning much.
The ranking by response volume is not subject to this floor: there is no average there to swing.
