Grad PLUS Was a Blank Check for Graduate School, and Here Is the Proof

Picture a store with a strange policy. Every customer may borrow, from the government, whatever the price tag says. No limit. No check on whether the customer can repay. Now ask yourself what happens to the price tags. That is a hypothetical, and I label it as one, but it is also a fair description of how federal lending for graduate school worked for nearly two decades.

The thesis of this post is simple. When Washington lent graduate students up to the full cost of attendance with no cap, graduate programs had little reason to hold their prices down, and the evidence of what happened is in the statute, the loan rules and the pricing of master's degrees. I will set out the history, state the case for the old system fairly, answer it, and then deal with the strongest objection to the new caps: that they will shut poorer students out of medicine and law.

The terms

A PLUS loan is a federal loan, originally created for the parents of undergraduates. Grad PLUS is the version available to graduate and professional students. The cost of attendance is a figure each school sets for a year: tuition, fees, books, housing, food, transportation and personal expenses. It is the school's own estimate, and a financial aid office can adjust it. A cap is a limit on how much a student may borrow.

How it started

In 2005 Congress passed the Higher Education Reconciliation Act of 2005, part of a budget package that became law in early 2006. Among its provisions was a change that lets graduate and professional students borrow under the PLUS programme beginning July 1, 2006. Before then, graduate students could borrow under the Stafford programme, which had annual and aggregate limits, and could turn to private lenders for the rest. Under the new rules, a graduate student could borrow up to the school's cost of attendance, minus other financial aid received. There was no fixed dollar cap. The ceiling was whatever the school said a year of attendance cost.

The loans required a credit check rather than a test of ability to repay. There was no test of whether the degree would produce income enough to repay.

Notice what that structure does. The school sets the cost of attendance. The cost of attendance sets the borrowing limit. The borrowing limit sets what students can pay. The school thus holds the pen at every point in the chain, and the federal government stands behind the loan at the end.

The steelman for the old system

The case for Grad PLUS deserves a fair hearing, and its defenders had good reasons.

One. Graduate education can pay. A doctor, an engineer and a lawyer earn more across a career than most people with a bachelor's degree, and the loans let students without family money enter those fields.

Two. Before 2006 the private market was uneven. Some students could not get private loans, or got them on poor terms, and the federal programme gave access to those who would otherwise have been shut out.

Three. It was available to students with decent credit and was not forgiving of default, since Grad PLUS loans carry the same strong collection rules as other federal loans.

Four. Caps hurt the poor. A student whose parents cannot co-sign a private loan is the one who most needs a federal one. Take away the federal loan, and you take away the student's path.

Those points deserve respect. The question is whether they justify a loan with no ceiling and no link to the price or the likely earnings.

The argument in numbered points

1. A price-insensitive buyer drives prices up. When the buyer can borrow whatever the school charges, the buyer has less reason to refuse a price. When the lender is the government, which does not price risk by programme or by school, the lender has even less. A school that raises its price meets no resistance at the checkout. This is not a controversial claim among economists who study education finance; the dispute is over how large the effect is.

1. The dispute has a pedigree. In 1987 William Bennett, then Secretary of Education, wrote in The New York Times that that increases in federal aid had enabled colleges to raise their tuitions, which became known as the Bennett hypothesis. For decades it was argued over. More recent work, including a 2015 study by economists at the Federal Reserve Bank of New York, found that expansions in federal loan limits were associated with tuition increases, with about sixty cents of each additional dollar of subsidised-loan maximums passing through to higher tuition in the version published as a 2015 staff report; later versions of the paper put the figure somewhat higher. That is one study, and researchers disagree, but the direction is what theory predicts.

1. Graduate programmes were the best place for it to happen. Undergraduate borrowing is capped by statute at modest annual amounts. Graduate borrowing was not. A school launching a new master's programme could set a price near the maximum a student could borrow, and the loans would cover it. Over the following years many universities launched or expanded master's programmes, some of them priced like prestige degrees and some leading to modest salaries. I would not call every programme a bad one. I would say the structure rewarded the school that priced highest, and it rewarded the school regardless of whether graduates could repay.

1. The cost-of-attendance rule made the ceiling movable. Because the limit was the cost of attendance minus aid, and because the school set the cost of attendance, a school could raise its living-expense estimate and so raise the amount a student could borrow. A student who did not need the money was allowed to borrow it, and was encouraged to by the formula.

1. Repayment rules weakened the last restraint. In 2007 Congress passed the College Cost Reduction and Access Act, which created Public Service Loan Forgiveness and income-based repayment. Grad PLUS loans are generally eligible for Public Service Loan Forgiveness, which forgives the balance after 120 qualifying payments while working in public service, so a graduate student in that path could borrow without limit and repay by a formula tied to income, not to what was borrowed. For a student expecting a low salary, the debt was in effect partly a grant. For the school, the signal was clear: price without worrying about repayment, because the taxpayer is the backstop. That is the loan equivalent of an all-you-can-eat buffet where someone else pays the check.

1. The borrower, not the school, bears the first risk. A school whose graduates cannot repay suffers no consequence under the old rules. A student does. A system in which the party who sets the price carries none of the risk will not produce prudence.

A worked example, labelled hypothetical

Consider a hypothetical two-year master's programme. Suppose the school's cost of attendance is $60,000 a year. Under the old rules, a student could borrow up to the full $60,000 each year, minus any grants, for a two-year total of $120,000 before interest. Suppose the typical graduate in the field earns $50,000 a year. The debt is 2.4 times the first-year salary ($120,000 divided by $50,000). Interest accrues during school.

Under the caps enacted in 2025, which I describe below, a graduate student who is not in a professional programme can borrow up to $20,500 a year, so $41,000 over two years. The shortfall against the school's $120,000 price is $79,000 ($120,000 minus $41,000). The school faces a question it did not have to ask under the old rules: will students pay $79,000 more out of pocket, find a private lender willing to take the risk, or choose a cheaper programme? The numbers are invented for illustration, but the mechanism is real: the cap puts price back into the conversation.

What Congress did in 2025

In July 2025 Congress passed, and the President signed, the law commonly called the One Big Beautiful Bill Act. Among its education provisions, it ended Grad PLUS for new borrowers beginning July 1, 2026, and set new limits on federal loans for graduate study. As I understand the provisions, which readers should confirm on the Education Department's pages because details are subject to implementation, they set annual and aggregate caps: for graduate students, $20,500 per year and $100,000 in total; for professional students, such as those in medicine and law, $50,000 per year and $200,000 in total; and a lifetime cap on federal student loans for an individual. It also limited Parent PLUS loans for undergraduates' parents.

The point to keep in mind is that students already borrowing under the old rules were generally protected for a transition period, and the changes apply to new borrowers. The caps move the system from "up to what the school charges" to "up to a fixed amount," which is the change that matters for price discipline.

The steelman against the caps: they will shut out the poor

Here is the strongest objection, in the words its defenders would use. A cap of $50,000 a year for professional students will not cover the full price of many medical and law programmes. A student from a wealthy family will pay the rest or find a private lender, and the student from a poor family will not. The cap therefore sorts students by family wealth, and shuts the poorest out of the professions, the very route up that Grad PLUS opened.

That deserves a serious answer, and I would offer five points.

1. The cap shifts the risk to those who can judge it. Private lenders underwrite loans according to the programme, the school and the borrower's prospects. A loan to a student in a high-earning field at a school with strong outcomes is a good risk, and private lenders will compete for it. A loan to a student in a low-earning field at a high-priced programme will be more expensive or unavailable. That is information the student needs before enrolling, not after.

1. The old system did not serve the poor best. The largest borrowing balances often sat with students in expensive, lower-earning programmes, and the debt weighed heaviest on those least able to bear it. A system that lets a student borrow $120,000 for a $50,000 job does not protect the poor. It endangers them.

1. Schools have resources, and now they have a reason to use them. The largest universities hold large endowments, and many medical and law schools already offer substantial institutional aid. A cap pressures schools to use it, to price lower or to share the risk of the loans their students take. Some have already begun to do so.

1. Other routes exist. Service-linked programmes, such as the National Health Service Corps, scholarships and employer assistance, tie money to service and to need. Those are targeted subsidies, which are fairer than an open-ended loan that anyone can use at any price.

1. If access is the worry, say so and fund it. If Congress believes that low-income students deserve help entering medicine, the straightforward answer is to fund scholarships openly and accountably. Hiding the subsidy inside a loan, then blaming the cap when the loan runs out, is the opposite of transparency.

I do not claim these answers dispose of the objection for every student. Some will find the cap a hardship, and Congress should watch what happens. Where the cap is shown to shut out able students in underserved areas or fields, a narrow fix should be on the table. But the right comparison is not "caps versus a perfect system." It is "caps versus a loan that fuelled the price it financed."

Why this matters to a family

Parents and students can use this history in practical ways. Before choosing a graduate programme, ask what graduates earn, not what the brochure promises. Ask what the total cost will be, and what share of students finish. Ask what debt the typical graduate carries. A programme that will not say is telling you something. See Where Tuition Dollars Go, From Administrators to the Lazy River for how the money moves inside a university, Biden v. Nebraska and the Limits of a Secretary's Power to Cancel Debt for the limits on executive debt cancellation, and Four Years of Wages Versus Four Years of Debt, the Apprenticeship Math for an alternative to the degree-and-debt path. The national picture is on the national debt clock.

The measure against the Founding

The Constitution gives Congress the power to spend for the "general Welfare," but it also reflects a fear of open-ended commitments that nobody has to answer for. Madison's Federalist No. 51 explains the principle: ambition must be made to counteract ambition, each actor's incentives set against another's. In a healthy lending market the lender's interest in being repaid restrains the borrower and the seller. Grad PLUS removed the restraint, because the lender, the government, did not price the risk. A conservative case for the 2025 caps is the old one: put responsibility back where decisions are made, and make the one who sets the price care whether the customer can pay.

The case in brief

1. The Higher Education Reconciliation Act of 2005 created Grad PLUS loans beginning in 2006, letting graduate students borrow up to the cost of attendance minus other aid, with no fixed dollar cap.
2. Because the school set the cost of attendance, and the cost of attendance set the loan limit, the party that set the price carried none of the risk of repayment.
3. Public Service Loan Forgiveness and income-based repayment, added in 2007, weakened the last restraint, and research on loan limits and tuition, including a 2015 New York Fed study, supports the Bennett hypothesis that more available credit pushes prices up.
4. In 2025 Congress ended Grad PLUS for new borrowers starting July 1, 2026 and set annual and aggregate caps, which brings price back into the decision.
5. The strongest objection, that caps will shut poorer students out of medicine and law, deserves attention, but private underwriting, institutional aid and targeted scholarships answer it better than an open-ended federal loan.

What you can do: before a family member borrows for graduate school, look up the programme's published graduation, debt and earnings data on the Education Department's College Scorecard, and ask the school for the figures it does not publish.
