Today is the SAT's 100th birthday.

On June 23rd, 1926, eight thousand and forty students — 4,829 boys, 3,211 girls — sat down at colleges across the country to take something brand new. No practice tests existed. No prep books, or any idea what to expect. Just a sealed booklet and a clock.

I found the actual test. And it is nothing like what you remember. But first let’s get into why we did this in the first place.

The test was built by Carl Campbell Brigham, a psychology professor at Princeton, adapted almost directly from intelligence tests the US Army used to sort recruits during World War One.

A profile of Brigham published that spring framed his ambition in almost romantic terms. The headline: "Scientist Starts 'Treasure Hunt' for Discovery of Hidden Genius."

The article's framing, translated from what it called "the scientific language of Carl C. Brigham": your maid might have the makings of an opera star. Your janitor might be a great novelist. Your butcher might have been a brilliant surgeon, if circumstances had ever given him the chance. Nobody ever looks. The talent stays buried.

Brigham believed psychological testing could find that talent. "The economic loss to society by its failure properly to train and develop every boy and girl of exceptional ability is very great," he said. "There must be hundreds of boys with extraordinary talent reaching college age every year, yet being unable to develop their talents because of economically disadvantageous positions."

It's a generous, almost utopian motive. Find the hidden genius in the overlooked kid. Give talent a fair shot regardless of where it started.

And in the same breath, Brigham admitted he had no idea if his method actually worked. "At present our knowledge of what constitutes a good test is limited," he told reporters that June. "After a test is given, we do not know just how much weight should be given to its results. But each year that tests are used, our knowledge will increase."

Colleges used it anyway. Because they were becoming overloaded with applicants and needed more metrics to separate them from one another.

Here's the structure. Three hundred and fifteen questions. Ninety-seven minutes. Nine sub-tests. That's about three questions every single minute. Students were explicitly warned they probably wouldn't finish, and told not to worry about it.

Here’s a selection: one question from each section.

Definitions. Match the missing word to its definition from a list of sixty-six options, half of them deliberately wrong:
"An ___ is an English linear measure, customary in the United States, the twelfth part of a foot."

Arithmetic. No calculators existed yet. You did this in your head, on the margin of the page:
"If a package containing twenty cigarettes costs fifteen cents, how many cigarettes can be bought for ninety cents?"

Classification. Six words, find the three that are most closely related:
"silver, platinum, amethyst, coinage, emerald, sapphire"

Artificial Language. This is the one that was genuinely surprising. An entire invented language — vocabulary, grammar, verb tenses — built from scratch, just for this test. You had to translate full sentences into it and back, having seen the rules for the first time minutes earlier:

"He pleases me" becomes "Ol thanto otceb."
Now translate the next twenty sentences. Same logic. Keep moving.

It wasn't only the official test that made headlines. That summer, newspapers across the country ran a different intelligence puzzle as a public stunt — designed by a Princeton graduate student named Paul Squires, originally meant for his fellow students, some of whom apparently found it genuinely difficult.

Stacked cubes, each face marked with a different symbol. You had to mentally rotate them through a sequence of rearrangements and call out the hidden faces from memory.

The headline asked readers directly: are your brains college-grade? It ran in paper after paper for months, daring ordinary adults who had nothing to do with the actual SAT to prove they had what it took.

Within a year, this had real consequences. Yale used the scholastic aptitude test in admissions for the first time in 1926, and reported that many fully qualified applicants were turned away anyway — not because of low scores, but because of strict class size limits. The test hadn't replaced judgment. It had just added a new layer to it.

The University of Pennsylvania made the test mandatory for all applicants shortly after, with its vice-provost explaining the reasoning plainly: with so many candidates and so few spots, the school needed every possible data point to determine, in his words, "which candidates have the moral and social qualities that will fit them to win the larger success in business or the professions."

A hundred years later, the SAT looks nothing like this. No invented languages. No cigarette math. No newspaper cube puzzles daring strangers to prove their intelligence. But the basic premise hasn't moved an inch: a single test, administered on a single morning, used to predict something genuinely difficult to predict — whether a seventeen-year-old is going to succeed.

Brigham wanted to find hidden genius in overlooked places. He also admitted, on the record, that he had no idea whether his test could actually do that. A hundred years and several redesigns later, people are still arguing about whether it does.
