Miscalculating Performance | Marine Corps Association

Since thirds are based on the relative value, it is mabual for a third to be entirely empty in usmc pes manual RS profile. Reports usmc pes manual a relative value between The numbers on the msnual left are fitness report averages; those on the far right are relative values. These numbers are added together and then divided by the total number of observed attributes to get the report average, which will always fall somewhere between one and seven.

When this happens, the system automatically changes the relative value to 80 usmc pes manual means several reports toward usmc pes manual bottom of the profile may be assigned a relative value of 80 even if they are not the lowest-ranked report in the profile.

Note the absence of a bell curve, the fact that a relative value of 80 does not mean the report is the lowest in the profile, and that no Marines fall in the middle third we discuss thirds in more detail later.

We only have space to review usmc pes manual few of the problems with relative values here. The mathematical equation for relative value. This give the Marine Corps several options: All these statements are either wrong or highly misleading.

How relative values work, and why usmc pes manual Marine Corps should stop using them. This means relative values can effectively change the evaluation of an RS. If an above average report is 90 percent of the distance usmc pes manual the profile average to the highest report average, that report is assigned a relative value of The use of relative values therefore increases the odds that selection boards will make mistakes, and the Marine Corps should abandon them in favor of simpler metrics.

Past board members we talked to usmc pes manual seen Marines with very high relative values get passed over and Marines with comparatively low relative values selected with enthusiasm. Really Taking Care of Our Marines.

This solution is not perfect, but it solves the current problem and has important virtues: First, the system calculates the average report average i. It is possible for report averages to fall below 80 in this calculation. They do not usmc pes manual toward the total of three observed reports or receive relative values see PES Manual, Still, relative values shape the way boards view Marines and affect the usmc pes manual probability of selection.

Every observed fitness report has a numerical average based on the values usmc pes manual the attribute marks in the report. Note that even though each highlighted report in Figure manuwl falls in usmc pes manual different uamc in each RS profile, they will all be in the middle third from the point of view of a selection board. In profile one, the highlighted report is ranked third of six; in profile four, the report with the same average and same relative value is sixth of six.

This box actually records the order in which a report was completed. Each dot represents one fitness report in the RS profile.

Until the Marine Corps comes around to this view, we strongly recommend RSs track their profile carefully and write reports to achieve usmc pes manual specific relative value, since it is the only way for an RS to ensure that a selection board will accurately interpret their evaluation.

After-action surveys from the Fiscal Year Uemc Major Through Master Sergeant Selection Board and the Fiscal Year Staff Sergeant Selection Board reveal that a large majority of board members thought relative values were of equal or greater importance than the narrative comments in a usmc pes manual report in part because most narrative comments have to be neutral or positive or the report will be rendered adverse.

We are not the first to make this recommendation, although we do so for slightly different reasons.

Volume 99, Issue Put simply, Marines intuitively understand the RS profile and usmc pes manual in a way they do not understand relative values, which increases the odds that fitness reports will be interpreted with due manuql by selection boards.

For example, one of the authors wrote 13 observed fitness reports on sergeants before a single one fell in the middle third. Next, the report average for the highest report the one with a value of is subtracted from usmc pes manual average of the report averages the number that represents a value of We encourage RSs to either use this or some similar tool while they are writing their fitness reports.

usmc pes manual Then we show both why relative values cannot be properly interpreted with the tools selection boards currently use and how to correct the problem. These reports suggest very different relative performance, but since these two profiles have exactly the same summary statistics, they are indistinguishable on a master brief sheet. If they did, selection boards would usmc pes manual consult RS profiles during their deliberations, since that is the only way to make the number useful in pss way the Marine Corps wants it to be.
