The italicized language below is from the NJCSC.

How is a candidate’s seniority score and final score calculated?

A candidate’s final score (and rank) on a New Jersey Civil Service Commission promotional list [for the position of Sergeant] consists of two weighted parts: the test score and the seniority score.

The seniority score is comprised of the time from the regular appointment date (of the eligible title) to the closing date of the announcement, minus the time spent on suspensions, layoffs, and regular leaves of absence without pay (other than military) such as educational, gubernatorial appointments, personal, sick, disability, family, voluntary furlough, furlough extensions, and to fill elective office (day for day deduction from length of service).

Seniority is weighted at 20% and test score is weighted at 80% for a Sergeant promotional examination.

Seniority is combined with the test score to produce the final average score.

CALCULATION OF SENIORITY SCORE

To a base score of 70.000, one point is added for each year of eligible service up to a maximum of 15. The maximum possible seniority score is 85.000.

---

What is not mentioned in the above description and may be what your looking for is the 10 points of service credit that essentially goes on top of the seniority score (for practical purposes), so the seniority score actually reaches a maximum of 95 points for a person who has the maximum 15 or more years of qualifying service as an officer.

(Test score × .8) + (Seniority Score × .2) = Final Overall Average Score

Example: Officer with 15 years of service, no discipline or lost credit, who scores an 88 on the actual exam.

88 (test score) × .8 = 70.4 (weighted exam score)

15 years + 70 base credit + 10 service credit = 95 95 × .2 = 19 (weighted seniority score)

Final Overall Average: 70.4 + 19 = 89.400

An officer with the exact same test score but with the minimum 3 years of qualifying service would be as follows:

88 (test score) × .8 = 70.4 (weighted exam score)

3 years + 70 base credit + 10 service credit = 83 83 × .2 = 16.6 (weighted seniority score)

Final Overall Average: 70.4 + 16.6 = 86.600

Now how did you come up with the 88?

I understand the rest of the formula.

90 question exam

Thanks for your response

The scoring of the actual exam based on the number of questions, etc., is a little more sophisticated than you would think. The CSC is required to conduct an "item analysis" which includes as assessment of Disparate Impact Doctrine issues , flawed questions (double-keying or omissions), point bi-serial correlation coefficient issues, etc. They have the ability to weight individual questions as well, but there is no indication they do that on promotional exams.

One thing you cannot do is simply say that on a 90 question exam, each question is worth 1.11 points. I tracked the scoring of the promotional exams each cycle for over 15 years and it literally never worked out the same from one cycle to the next.

You'll drive yourself crazy trying to figure it out.
