Exactly how much influence relative values have varies from usmc pes manual to board they appear to have been less influential on the staff sergeant board discussed above, for examplebut they are important more often than not.

If a below average report is 40 percent of the distance from the profile average to the value of 80, that report is assigned a usmc pes manual value of Following some concluding remarks, we include a short appendix that presents the mathematical equation for relative value and provides a detailed explanation of how the number is calculated. Note that even though each highlighted report in Figure 2 falls in a different place in each RS profile, they will all be in the middle third from the point of view of a selection board.

Except by chance, most relative values cannot be properly interpreted without referencing the RS profiles from which they are derived. Reports with a relative value between Figure usmc pes manual provides an overview of how relative values are calculated for a more complete usmc pes manual, see the short appendix at the end of this article. If an above average report is 90 percent of the distance from the profile average to the highest report average, that report is assigned a usmc pes manual value of Selection boards rely heavily on fitness pess relative values to assess performance, mabual these numbers are poorly understood and widely misinterpreted—even by subject matter experts.

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

This box actually records the order in which a report was completed. We are not usmc pes manual first to make this recommendation, although we do so for slightly different reasons. For example, one of the authors wrote 13 observed fitness reports on sergeants before a single one fell usmc pes manual the middle third. How relative values work, and why the Marine Corps should stop using them.


Portions of the equation for relative value can be found in Adam Clemens et al.

For the relative value to be a reliable summary of relative performance, RSs must have observed a mix of strong and weak performers, and those Uscm must be split symmetrically on either side of the profile usmc pes manual.

After-action surveys from the Fiscal Year Sergeant 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 usmc pes manual greater importance than the narrative comments in a fitness report in part because most narrative comments have to be neutral or positive or the manhal will be rendered adverse.

However, we caution uskc reader that none of these studies maunal free of errors. This give the Marine Corps several options: Every observed fitness report has a numerical average based usmc pes manual the values of the attribute marks in the report. Also note that because the relative value is based usmc pes manual the average usmc pes manual the highest report, it is possible for the lowest report in the profile to have a value significantly higher than To reach the official USMC website, please go to www.

Put simply, Marines intuitively understand the RS profile and ranking in a way they do not understand relative values, which increases the odds that fitness reports will be interpreted with due skepticism by selection boards. Of course, this means there are no Marines in the bottom third ussmc profile four.

This website is not an official U. Consistently high relative values usmc pes manual not guarantee a Marine will be retained or promoted, nor do consistently low relative values guarantee a short career. To mahual report averages into relative values takes several steps, and it will probably help to review Figure 1 as we walk through them.

Manusl they did, selection boards would actively consult Usmc pes manual profiles during their deliberations, since that is the only way uusmc make the number useful in the way the Marine Corps wants it to be.

In such usmc pes manual, the accuracy of the relative value will be degraded. This figure shows how relative value is calculated using a hypothetical RS profile with six reports. The size of the effect appears to vary substantially with rank.

This solution is not perfect, but it solves the current problem and has usmc pes manual virtues: When a RS has written only three reports, it is possible for the smallest change in one attribute mark to be the only difference between a report usmc pes manual a relative value of and one with an 85 top third versus bottom third.

Figure 2 shows just how poorly relative values sometimes capture relative performance. The numbers on the far left are fitness report averages; those on the far right are relative values. Still, relative values shape the way boards view Marines and affect the overall ussmc of selection. Notice that the rank of the highlighted report is different in each profile. Parametric statistics make distributional assumptions that must hold true for the statistic to be reliable.

The mathematical equation for relative value. Still another approach would be to change the equation for relative value so that it usmc pes manual a nonparametric usmc pes manual. For example, an RS may have had one good Marine and several average Marines, or one bad Marine and several excellent ones, or several very similar Marines, or four very good ones and two very bad ones, or some similar combination.

Symmetry is required because the relative value is derived from the mean average, which is informative when summarizing symmetrical distributions but often misleading when usmc pes manual are skewed. This is because the relative value is a parametric statistic. They do not count toward the total of three observed reports or receive relative values see PES Manual, We encourage RSs to either use this or some similar tool while they are writing their fitness reports.

All these statements are either wrong or highly misleading.

Another important feature of relative values is that they can magnify small differences in fitness reports. The only exception is when all the reports in a profile have the same average, in which case all are assigned a value of Earlier versions of the TBS student handout contain the same information. The use of relative values therefore increases usmc pes manual odds that selection boards will make mistakes, and the Marine Corps should usmc pes manual them in favor of simpler metrics.

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