Every Jewish day school publishes a number. Then financial aid, sibling discounts, staff remission, and unpaid balances go to work on it. So we took a national benchmarking panel and matched each posted price to the revenue year it went on to produce. The school collected about 74 cents of each posted dollar. This essay follows the other 26.
The median US Jewish K–8 school posts $26,215 in tuition and books $18,688 per student. Measured school by school, the typical shortfall is 25.7% of the posted price, about $6,741 per student.
One word, "tuition," is doing the work of three different numbers: the price a school publishes, the amount families are billed after aid and discounts, and the revenue the school collects in the end. Public conversation collapses them into one figure, and the collapse hides both what families really face and what schools really live on.
The gap barely moves. Two different sets of schools in two different years produced medians of 25.7% and 25.7%. Swap in alternative price definitions and the estimate stays between 23% and 29%, and an independent accounting check lands at 25.9%.
And it is an institutional number, never a family's. The 26 cents that never arrive are a blend of need-based aid, sibling and staff discounts, targeted affordability plans, uncollected balances, and accounting conventions. What any one family pays is a different question, and a different dataset.
One more caution before the charts. The gap measures tuition against tuition, never against what a seat costs. Even a school that collected every posted dollar would likely still need to fundraise. The gap is the shortfall against the sticker; the shortfall against the actual cost of the program is bigger, and this essay comes back to it.
Published tuition is neither the typical family's payment nor the school's realized revenue. Treating it as either one distorts everything downstream.
What does the word tuition actually mean?
Start with one family: two children, one school. The website says $26,215 per child, the median posted price in this panel, so on paper this family owes $52,430 a year. That is the published price, the first of the three numbers and the only one a family can see from the outside.
The second number arrives after the aid committee, the sibling discount, and any staff remission have each taken their turn: the amount the family is actually billed. Maybe it is $52,430. Maybe it is half that. The website doesn't say, and for many families the first number decides whether they ever ask. The third number shows up months later in the audited books: the revenue the school collected, from this family and every other one.
Families argue about the first number. Boards budget against the third. No benchmarking dataset can see any single family's bill, this one included. What it can measure is the distance between the first number and the third, school by school, with each posted price matched to the revenue it went on to produce. That distance is what this essay is about.
How far apart are the price on the website and the money in the books?
The chart below puts the two side by side for the median school-year. There are three columns. The blue one on the left is the price the school publishes, drawn from the floor up. The green one on the right is the revenue the school actually books per student, also drawn from the floor. The amber column in the middle is different: it does not start at the floor at all. It hangs between the top of the green column and the top of the blue one, and its height is the money that never arrives.
Notice that the amber column is about a quarter as tall as the blue one.
Take a school posting $20,000 with 100 students. On paper that is $2.0 million of tuition. At the median gap the school books $1.48 million, and the missing $520,000 could be a handful of large aid awards, many small discounts, staff remission, or balances that were never collected. Same total, very different stories.
Is every school close to that median?
No school is the median school. The chart below lays the whole panel on a single line, running from a gap of zero at the far left to a gap of 60% at the far right, so the further right you look, the less of its sticker a school collects. The shaded amber block is the middle half of school-years. The three dots on the line are the tenth percentile, the median, and the ninetieth.
Look at how far the right-hand dot sits from the left one.
Say it posts $26,000 and enrolls 250 students, so the year opens with $6.5 million of tuition on paper. At a 45% realization gap, about $3.6 million arrives as net tuition revenue and roughly $2.9 million never does. A school like this is unusual in the panel but far from imaginary: at the 90th percentile the gap reaches 53.3%.
Now notice what the number cannot tell you. That $2.9 million could be the community's proudest line item, seats filled by families who could never pay sticker, subsidized on purpose. It could be a sticker nobody is really asked to pay. It could be bills that went out and never came back. Same 45%, three very different schools, and only the school's own books can say which one this is. The data can size the wedge; it cannot judge it.
So does the typical family get a quarter off?
It is tempting to read the headline as "the average family gets a quarter off." The data cannot support that reading. The gap is measured at the institution: all revenue over all enrolled students. The two-child family from the opening might pay every dollar of its $52,430 while their school still shows a 26% gap, because the wedge is a blend of everyone, and many different mechanisms drain it.
Some of these are access investments a community should be proud of. Others are leakage. From the outside, a school investing in economic diversity and a school failing to collect its bills can post the same 26%. That is why the paper wants schools to publish the whole waterfall, posted price to billed tuition to collected revenue, instead of one opaque number.
Does the answer survive if you measure it a different way?
Each row in the chart below is one way of defining the sticker price, and the dot on each row is the median gap that definition produces. The scale runs from 21% on the left to 32% on the right, so a dot further right means a bigger shortfall. The bold row with the large amber dot is the paper's preferred definition. The shaded band behind the rows is the range the plausible definitions cover. The last row, in italics with a dashed stem, is the deliberately wrong one, kept in to show what a definition error looks like.
Notice that five of the six dots land inside the shaded band.
Families say tuition is impossible and schools say tuition does not cover them. Who is right?
Day school conversations often stage a standoff: parents say tuition is impossible, administrators say tuition doesn't cover the school. The realization gap shows how both can be right at once, because they are talking about different numbers.
Families anchor on the published rate, the biggest and most visible figure, and research shows a high sticker can discourage a family before it ever asks about aid.
And it is true: the median posted price in this panel is $26,215 per child, before siblings.
Schools live on realized revenue, which runs a quarter below the sticker, and the literature on small schools suggests it often sits below the true cost of a seat.
And it is true: the median school collects $18,688 per student, whatever the website says.
The standoff dissolves once the two numbers are named. And naming them exposes a third number neither side controls: what a seat actually costs.
This is where fundraising comes in, and why the gap understates the hole. The wedge in this essay is a theoretical shortfall against the school's own posted price. Suppose it vanished tomorrow and every family paid full sticker. The appeal letters would still go out, because a sticker is a price the school sets under market pressure, not the cost of running a dual-curriculum seat, and at many schools even a fully collected sticker may not cover that cost. This data does not measure cost per student, but the small-school literature points one way: limited scale and high fixed costs push the price of the program above what tuition brings in.
So a school really runs on three streams. The tuition it collects. The wedge it absorbs. And the money it raises on top of both. Narrowing the gap helps; it does not close the books, and a board that treats full collection as the finish line has planned for the wrong race.
So: a school posts a tuition price. How much of it actually arrives?
About 74 cents on the dollar, in participating US Jewish K–8 schools. The result holds in both years, under every reasonable definition, and in an independent accounting check.
The 26% is a benchmark, and that is all it is. It marks where the field's median sits, not where any school should aim: the right gap depends on what fills a school's wedge and why. Remember too that it measures the shortfall against the sticker, not against the cost of a seat, so the fundraising dinner survives even in the world where everyone pays in full. The paper asks the field for one practical thing: show the waterfall. Report posted price, billed tuition, aid, remission, and write-offs as separate lines, so a school that spends the wedge on access stops looking identical to a school that cannot collect its bills.
The panel covers US schools in Prizmah's Orthodox and non-Orthodox K–8 benchmarking cohorts: 78 year-aligned school-year observations from 47 schools, with an accounting validation drawing on 125 school-year observations from 56 schools. Reporting is voluntary, so the results describe participating schools and should not be generalized to Chassidic, Yeshiva World, high-school-only, boarding, or special-education institutions without further evidence.
Published tuition covers grades 1–12, while total enrollment can include preschool and other divisions, and net tuition revenue can include multiple programs and fees. Depending on a school's mix this can push its measured gap in either direction. That mismatch is why the independent gross-to-net accounting comparison matters: it avoids the enrollment denominator entirely and still lands at 25.9%.
The dataset holds no family-level bills, incomes, aid awards, or payment histories. It cannot say what the typical family pays, how many families pay full price, or whether aid is progressive, and it makes no causal claim about how discounting affects enrollment or access. The 25.7% is an institutional revenue measure, full stop.
Only two published-tuition years can be aligned to subsequent financial reports, and the school lists differ across them. The near-identical annual medians are reassuring about the estimate, but they are not a trend, and school-reported administrative data can carry definition and timing differences that the master file cannot see.
The gap compares realized revenue to the school's own posted price. It says nothing about instructional cost per student, which this dataset does not contain, and so it cannot say how large the remaining hole is after every tuition dollar arrives. The claim that fully collected tuition may still sit below cost rests on the small-school literature on scale and fixed costs, not on a cost measurement here; sizing that second gap would take cost data the field does not yet report in a common format.
A single school-year shows net revenue per student above the published-tuition measure. It was kept in the sample, because fees, grade mix, timing, and reporting conventions can legitimately produce such a value, and deleting inconvenient observations would bias the distribution.
