Part 7 of 8 in The Office That Tripled

The gap that isn’t there

I expected to find a gap. Women’s median salary in the School District of Philadelphia is $66,843. Men’s is $67,638. That is 99 cents on the dollar, which in pay-gap terms is a rounding error, and it is the kind of number an institution puts in a press release. Then I split the District’s own position roster by where people actually work, and the gap showed up twice, pointing in opposite directions.

In the central office, women’s median salary is 21% higher than men’s. In the schools, it is 10% lower. Add the two together and you get the 99 cents. That is not a district that has solved pay equity. That is two different districts sharing one payroll file.

Where women earn more

In the central office — the headquarters tier that grew from 1,432 positions to 4,228 over eleven years, which is what this series has been about — the median salary is $85,113 for women and $70,636 for men. There are 1,922 women and 1,115 men in that tier. It is the highest-paid bucket in the District outside school administration, and women hold roughly two-thirds of it.

The top of that tier surprised me most. Of the 53 central-office positions paying $175,000 or more — the C-suite layer that grew 10.6x in eleven years, 19 of them Assistant Superintendents added in a single year — 31 are held by women and 22 by men. The senior leadership layer SDP built during the expansion is majority-female.

School support is the other place women come out ahead: a median of $33,452 against $28,326 for men, 18% higher. These are classroom assistants, special-education aides, school secretaries — 4,936 women against 977 men. The ratio is not the number to hold onto here. The level is. Eighteen percent more than $28,326 is $33,452, and both of those are numbers you cannot raise a family in Philadelphia on.

And where they earn less

Now the school-based workforce — everyone assigned to an actual school building, which is teachers, aides, principals, counselors, building staff, and about 82% of everyone SDP employs. Women’s median there is $62,844; men’s is $69,505. Women earn 10% less in the part of the District that most Philadelphians mean when they say “the school district.”

So the same institution produces a 21% premium for women at headquarters and a 10% penalty in the buildings, and the two cancel almost exactly in the headline. I don’t think the headline is a lie, but it is a number that describes nobody.

The sorting, not the gap

The roster records a job title and a pay rate, not what anyone does all day, so I grouped the District’s roughly 1,900 distinct titles into nine named role families plus a catch-all, and sorted them by how female each one is. That list is the story the 99-cent headline cannot tell. Food services is 88.9% female — 88 women, 11 men. School support is 83.5%. Teachers are 73.4% — 6,921 women against 2,503 men. School administration is 70.1%, and the central-office family is 69.7%.

There is exactly one role family where men are the majority: building services, 784 men against 558 women. Carpenters, painters, electricians, custodians, the people who keep the buildings standing. Their median is $45,726 for men and $42,076 for women — a mid-pay blue-collar tier, and the one part of this roster that looks like the trades workforce anywhere else in the city.

Read the two charts together and the shape is sharp. Women hold both ends of the pay ladder: the lowest-paid front-line jobs (support at $33,452, food services at $27,241) and the highest-paid headquarters jobs (school admin at $129,970, central office at $85,113). Men are concentrated in one place, the middle, doing physical work. Inside almost every role family the pay gap is small or literally zero. Between the role families it is the whole thing.

Why five families match to the dollar

Five of the ten role families show identical male and female medians: teacher ($94,011), school admin ($129,970), safety ($44,733), food services ($27,241), and per diem ($35,676). Not rounding to the same number — the same number.

The reason is the salary schedule. Teachers, principals, safety officers, food-service workers, and per-diem staff are all paid on step-and-lane grids: years of service on one axis, degree credits or job classification on the other. A first-year teacher with a bachelor’s earns what every other first-year teacher with a bachelor’s earns. Inside a single cell of that grid there is no room for a gap, because there is nothing to negotiate — the number is the number, and it is printed in a contract anyone can download.

I don’t read that as SDP having solved gender pay equity. I read it as SDP having removed the mechanism that produces gaps everywhere else. The union did that, not a District initiative. Which is also why the two role families with real gaps are the two the grid doesn’t cleanly cover.

Where the real gaps are

Three role families come out below parity for women. Transportation is the widest: a median of $32,399 for women against $52,793 for men. The catch-all “other” bucket is close behind, $29,973 against $53,311. Building services is the third and by far the smallest, $42,076 against $45,726 — an 8% gap.

Both of the big ones need a caveat, and the caveats point at me rather than at SDP. “Other” is a taxonomy residual — 1,689 people whose titles didn’t match any of my nine named families — so the median difference there is telling me about my own classification before it tells me anything about pay practice. Transportation is a real family, 531 people spread across bus attendants, dispatchers, and depot staff, and my read is that men sit in the higher-paid titles inside it rather than being paid more for the same title. That is a guess. I’d want a title-level breakdown before saying anything stronger, and I haven’t run one.

What this can’t tell you

This is one year. SDP publishes gender back through 2014-15 and I didn’t pull the trend, because the finding I care about is the within-year split rather than the change over time. The cost of that choice is real: I can’t tell you whether the central-office inversion arrived with the positions the headquarters added over the last four years, or whether it was always there and nobody looked.

The pay figures are salaried positions only. I use that filter across this series because the roster’s hourly annualization turns a $580-an-hour per-diem lunch aide into a seven-figure earner, but it also cuts most of the part-time workforce out of the picture, and that workforce is heavily female. If hourly staff were included on some defensible basis, the school-support and food-services numbers would move. I don’t know in which direction. The 505 rows with a blank gender field are excluded for the same reason — no way to place them.

And none of this answers the question a reader might actually want answered: whether a man and a woman in the same title, with the same years in, are paid the same. For the union families the grid says yes by construction. For the administrative titles, where pay is negotiated individually, the roster gives me a median and nothing else.

What it means

The data does not support a men-versus-women framing of the School District’s workforce. The overall ratio is 99 cents. In the tier where the highest-paid positions live, women earn 21% more at the median and hold 31 of the 53 seats above $175,000. In the tiers where the front-line jobs sit, women are 84% to 89% of the workforce and earn between $27,000 and $33,000. The women winning inside SDP are winning in the office that tripled. The women at the other end of the roster are serving lunch for $27,241.

If you wanted to flatten the gap that does exist, the salary schedule is not the lever — it already produces equality by construction, in five families, to the dollar. The lever is which jobs people get sorted into and what those jobs pay, and SDP does not control the second half of that.

I want to be honest about what this does to the argument I’ve been making across this series. Four pieces in, my position is that the District’s $169 million in 2026-27 cuts should land on the central office rather than on schools. The central office is also the one place in the District where women out-earn men, where 31 of the 53 top-paid seats are held by women, and where the tier is roughly two-thirds female. Shrinking it means shrinking the part of the institution where women have done best. I still think the cuts belong there — the 130 frozen positions were vacant, and the case against a headquarters that tripled while enrollment fell 12.6% doesn’t change based on who holds the jobs. But the two findings touch, and I’d rather say so than let eight pieces run as though they don’t.

Notes, Sources, and Methodology

All figures are from the SDP position roster, 2025-26 snapshot, filtered to GENDER in F or M — 505 blank-gender rows excluded. Pay basis is salaried positions only; the roster’s hourly rates annualize at 1,800 hours, which turns part-time roles into apparent high earners (a noon-time aide at $580/hr annualizes to $1.04M) and would dominate any median. The C-suite definition is annual salary of $175,000 or more within central administration — the same 53 positions covered in the second piece of this series.

Two lenses on “central office” appear here and they are not identical. The pay figures ($85,113 vs $70,636; 1,922 women and 1,115 men) use the strict headquarters classification, the same one used across this series. The 69.7%-female share uses the broader role-family grouping, which also catches managers and analysts based at schools. The role-family taxonomy comes from keyword rules over the roster’s ~1,900 distinct titles and is shared across all eight pieces in this series; the “other” bucket is the residual, and I treat its gap as a classification artifact rather than a finding.

This is a 2025-26 snapshot, not a trend. SDP’s roster carries gender back to 2014-15; I didn’t pull the longitudinal series because the interesting finding is the within-year split. The roster counts funded positions rather than people, records pay rate rather than total compensation, and cannot distinguish someone promoted into a headquarters job from someone hired into one.
