Performance Ranking
Using the Scaled Comparison
The Scaled Comparison asks a rater or evaluator to compare the performance of two individuals using the following format:
| Question: |
Which person demonstrates greater Leadership ability? |
| |
Much
Better |
Slightly
Better |
Equal |
Slightly
Better |
Much
Better |
|
| Doug Reichman |
 |
Jim Craig |
|
|
The task is to indicate which person demonstrates greater ability than the other in some quality and how much greater the difference.
In the actual rating process, the evaluator is presented with many such pairs rather than a single pair. Each person being rated is paired with each of the others a number of times.

The evaluator will only see the names of people known to him or her well enough to evaluate on the criterion. Typically, the names of from 5 to 15 persons will appear on a page, matched in different ways with the others. Some of these names will appear in another evaluator's group of subjects. Each person is thus judged by more than a single evaluator, and eventually compared to others in many more ways than any single evaluator could accomplish. A second criterion can appear on the next page, and so on.

The Reports
The Scaled Comparison produces reports that illustrate and summarize the way the evaluators viewed the performances of all the individuals who were rated.
The Confidence Interval Report shows clearly and in detail the relative differences between subjects on each of the criteria. But more than just a ranking, the Scaled Comparison shows the intervals between the people being evaluated. Some people are very similar in their performance, others who are close in the ranking may actually be very different from the ones around them.

The Profile Report shows each individual's strengths and weaknesses by criteria. A composite score can be calculated to be either unweighted or weighted according to the importance of the criteria in the individual's job.

|
Other reports summarize the behavior of raters and the decisions they made that were unique and different from the consensus.
