What is the best population size to use when determining the modal rating?

The agency will have to determine the modal rating based on the rating of record information it has available. The Office of Personnel Management recommends that the modal rating, which is based on the most recent ratings of record, be tabulated for the specific competitive area undergoing a reduction in force whenever possible, and that larger aggregations of agency population be used only when the rating of record information is not available for the specific competitive area itself.
