COER Score Calculations

COER calculations are performed using the following values for graded elements: E = 100, D = 80, C = 60, B = 40, and A = 20.

To calculate the COER score, multiply the number of letter ratings by the number of points assigned to each letter, as seen in the table above.  Divide the total score by the number of letters (Ratings for letters A-E only).  The overall COER Score is the letter assigned to topic #18. This letter should be reflected as the officer’s overall COER score.

Remember: “F” ratings do not count for any points when calculating the COER score, nor should “F” letter ratings be included in the divisor.  The total number of letters that will be used as the divisor may vary for each officer, but the divisor should never be greater than 17.  Also, do not include topic #18, when calculating the COER score.  The letter rating assigned to topic # 18 serves as the officer’s overall COER score.  The officer should receive a numeric and letter COER score for all COERs on file, with the exception of the Narrative COER.  Narrative COERs only receive a letter score to determine “Satisfactory” or “Unsatisfactory” performance as denoted by the Rating Official in Topic # 18.


Example:

Officer received      5 E’s   5 x 100 = 500
                      8 D’s   8 x  80 = 640
                      1 C     1 x  60 =  60
                     ________________________
                     14 Letters        1200

                     1200 / 14 = 85.714 ~ 86

Officer received: For Topic Number  7, a letter rating of “F”.
                  For Topic Number 15, a letter rating of “F”.
                  For Topic Number 17, a letter rating of “F”.
                  For Topic Number 18, a letter rating of “D”.

Officer’s Total COER Score:     86 / D
