About county governments in New Jersey
New Jersey's 21 counties run services that cross municipal lines: courts, county roads, parks, corrections, and often social services. A county's civil service status covers its own direct employees; the municipalities inside it each make their own separate decision about whether to join the system.

Civil service examination announcements
4 examination announcements naming Middlesex County are open for filing. Who may file differs by row.
These are examinations, not job vacancies. Passing one places you on an eligible list; it is not an offer of employment, and this site does not track openings. Filing is with the Civil Service Commission, not with us.
Open competitive examinations
These are open to anyone who meets the published requirements, inside or outside government. Residency or other conditions may narrow who may file, and the announcement itself is the authority on that.

Source: the New Jersey Civil Service Commission's own examination announcement lists, read on October 13, 2026, with each row linked to the announcement it was read from. The Commission posts promotional announcements on the 1st of each month and removes them after about three weeks, so recently closed announcements are kept here rather than dropped. Every date and every title here is the Commission's. An announcement is matched to this employer by the name it carries, exactly; where a name is ambiguous we leave it unmatched rather than guess.

Who is on the pension rolls at Middlesex County
1,683 people are enrolled in a State-administered pension fund through Middlesex County. That is a count of active memberships reported by the employer, not a payroll headcount: anyone not enrolled in one of these funds does not appear in this data at all, and no separate headcount for a New Jersey local employer is published anywhere we can check against.
| Fund | Name | Members | Share |
|---|---|---|---|
| PERS | Public Employees' Retirement System | 1,282 | 76% |
| PFRS | Police and Firemen's Retirement System | 401 | 24% |
Within PFRS, the fund records 398 police officers and 3 firefighters. PFRS enrolment is the only occupational detail this dataset carries; it lists no job titles, so nothing here says which civil service titles Middlesex County actually appoints.
19 of these members hold a second public job in New Jersey: their reported salary across all public employers exceeds what they are paid here. Shared and part-time appointments are common in local government, and the salary figures below count only the portion earned at Middlesex County.
Pensionable salary at Middlesex County
Half of the pension-enrolled workforce at Middlesex County reports a pensionable salary above $66,257 and half below, across 1,683 members with a reported figure.
| Point in the distribution | Pensionable salary |
|---|---|
| 10th percentile | $43,704 |
| 25th percentile | $51,982 |
| Median | $66,257 |
| 75th percentile | $94,778 |
| 90th percentile | $127,550 |
The range runs from the 10th to the 90th percentile because the extremes are not informative: the lowest reported figures belong to part-time and partial-year members, whose credited salary is a fraction of a full-time equivalent.
Among the 11 civil service jurisdictions in the same county with pension data, that median sits at the 9th percentile, below the county's midpoint of $75,739. Against the 20 bodies of the same kind statewide, it sits at the 65th percentile.
These figures are pensionable salary reported to the NJ Division of Pensions and Benefits for the four most recent quarters, not total pay and not take-home pay. Snapshot of March 31, 2026. How we compile this.

What civil service status means for jobs at Middlesex County
A county government is among the largest employers in this directory, and its civil service status reaches across the county jail, the road and bridge crews, the parks system, the clerk and surrogate offices, and in most counties a share of health and human services staff.
Several county titles have no municipal equivalent at all. County correctional police officer is the clearest case: its own entry examination, its own academy requirement, and its own closed promotional ladder up through sergeant, lieutenant and captain. A county's status also stops at its own payroll, which is why a county can operate under Title 11A while most towns inside it do not.
Passing an examination puts you on an eligible list, not into a job. Lists are promulgated for a fixed life, commonly three years, and the Commission certifies names from the live list whenever an employer reports a vacancy. If no list exists for a title when a vacancy opens, the employer has to ask for an examination to be held.
New Jersey does not require an employer to hire whoever scored highest. When a list is certified, the appointing authority may choose among the top three interested candidates, which is why a rank of two or three on a list is still a serious position and why interviews still decide outcomes.
Countywide civil service employers in Middlesex County
Middlesex County is the county government itself, so its civil service status covers county employees rather than anyone working for a town inside the county. Municipalities, libraries, authorities and districts each decide separately, and most of the county's towns are not in the listing at all.
Two other countywide bodies in Middlesex County are in the listing as well. They are separate employers with separate hiring, and a candidate list certified to one is not certified to another.
- Middlesex County Board of Social Services, board of social services
- Middlesex County Mosquito Extermination, mosquito extermination commission

Common questions about Middlesex County
Is Middlesex County a civil service employer?
Yes. Middlesex County appears in the New Jersey Civil Service Commission's listing of local civil service system jurisdictions as of July 2024, which makes it an appointing authority under Title 11A. Permanent appointments to competitive titles there come from eligible lists the Commission certifies, rather than from purely local hiring.
Is the job specification the same everywhere?
Yes, and that is the point of the classification system. A title has one specification statewide, covering the definition of the work, the education and experience requirements, and any licence the title depends on. That is what makes experience gained at one civil service employer legible to another, even in a different county.
Are there jobs here that never go through an examination?
Yes. Unclassified positions, which typically include department heads and confidential staff, are filled at the discretion of the appointing authority. Noncompetitive and labor titles inside the classified service are also filled without a competitive examination, though they still sit under civil service rules for things like layoff rights.
How many Middlesex County employees are in a State pension system?
1,683 active memberships are reported through Middlesex County, split across 1,282 in PERS and 401 in PFRS. This counts pension enrolment rather than payroll, so employees who are not in one of these funds are not included.
What is the median pensionable salary at Middlesex County?
$66,257, with the middle half of members between $51,982 and $94,778. These figures are pensionable salary reported to the NJ Division of Pensions and Benefits for the four most recent quarters, not total pay and not take-home pay. It excludes overtime and most supplemental pay, and it is before tax, before the member's own pension contribution and before health premiums.
How does pay at Middlesex County compare with the rest of Middlesex County?
Its median pensionable salary of $66,257 sits at the 9th percentile among the 11 civil service jurisdictions in Middlesex County with pension data, where the midpoint jurisdiction reports $75,739. Local pay is set by ordinance rather than a State schedule, so spreads inside one county are wide.
How long do people stay at Middlesex County?
The median enrolled member has 9.7 years of credited service, and 24% have passed twenty years. Credited service drives both retirement eligibility and the pension formula, so a long-tenured workforce usually means fewer open competitive appointments in the near term.
