Hansford County, TX county · a true story and the evidence

Girls Are Great At Math — Hansford County, TX

“Looks like you found your calling in life.”

Hansford County is one of 254 counties in Texas. Somewhere in that number is the girl this page is about, and an adult who is about to say the wrong thing without meaning any harm by it.

One sentence, from the teacher everyone loved

Ellis Abel's mom was a little girl who saw the classroom trash was full and took it out. Nobody asked her to. She just did it.

Her teacher — the popular one, the one all the cool kids loved, the one everybody wanted — looked at her and said: “Looks like you found your calling in life.”

She meant it the way it sounds.

The most popular teacher in the school

That is the part worth sitting with. This was not a bitter, unpopular teacher nobody listened to. This was the favorite. The one with the reputation. The one whose approval the whole class wanted.

A person can be loved by everyone and still be carrying something bad, and hand it to children one line at a time. She probably said versions of that sentence for thirty years. She probably aimed it at the ones with the most in them, because those are the ones who make an insecure adult feel smallest.

There is no way to count how many young leaders she trapped inside her own insecurity by telling them, early, that they would never amount to anything past laborer.

A few hundred feet from a fully paid education

She grew up in the second poorest county in the United States, on the border with Mexico.

Here is the part that is hard to hear. Had she been born a few hundred feet south of her own home, the state of Texas would have paid for her entire college education. That program still exists.

Her ancestors' choice of which side of a line to stand on meant she had to climb out of that poverty with less support than people who were not born in this country. She did not get the help. She went anyway.

It did not stop her. It lit her.

She paid for college out of her own pocket and earned a degree in Marketing.

At twenty-three she was the United Kingdom Country Manager for a major American company. At twenty-four she finished her MBA.

And she tutored United States Air Force fighter pilots — and other professionals at that level — in graduate-level mathematics and statistics. Fighter pilots are not selected for being bad at math. She was teaching them the hard parts.

Fifteen years of being underestimated by one man

In an interview with a Fortune 10 company, a man dismissed her. He later became her boss. He had a PhD in mathematics.

It took him fifteen years to admit out loud that she was his equal in math. For fifteen years before that he talked down to her work, because he had never taken the time to know his own people. He assumed she was not qualified — and assumption is cheaper than attention.

So he passed her over. Repeatedly. And hired people less qualified than she was to be her boss.

She stopped waiting for the door to open

She built her own business.

Then she made her work inside that company matter enough that they created a promotion that had not existed before her. Not a promotion she applied for. One that had to be invented because there was no box she fit in.

She poured herself into developing data scientists. Her people kept getting pulled off her team and moved to weaker ones — because the company believed those individuals were exceptional. They never worked out that it was her leadership making them exceptional. She kept developing them anyway.

Where she is now

She is one of the best data engineering and advanced analytics directors at one of the largest technology companies in the world. In terms of success in STEM, that puts her in well under one percent of the people alive.

She also became a European Grand Champion martial artist — National Champion in three different countries, with gold medals across five different categories.

She has traveled the world many times over and lived abroad for years, in places the girl taking out that trash had no reason to think she would ever see.

And the teacher

She never left the small town.

She died popular.

She never found what she would have called a true calling in life — unless placing doubt in the minds of young leaders counts as one.

That story is not here to make anyone the villain. It is here because it is what actually happens, and it is still happening this week, in a classroom near you.

Girls do not need to be talked into math. They need adults to stop talking them out of it — sometimes on purpose, and far more often without meaning to at all.

There is a version of that teacher in Hansford County, and a version of that girl. Both are in a classroom this week.

What the numbers actually say

Every figure names its source and its year. Popular claims that do not hold up under scrutiny were left out deliberately — this argument does not need them.

4 points

The gap is tiny, and it moves

On the 2024 NAEP math assessment, eighth-grade boys averaged 274 and girls 270. In 2019 girls were nominally ahead — 281.5 to 280.5. A difference that swings by five points in five years is not written into anyone's biology.

NAEP, The Nation's Report Card, 2013–2024

28%

In more than a quarter of US school districts, girls are ahead

Across roughly 10,000 districts and 290 million test records, 28% show math gaps favoring girls, and the average gap nationally is 0.027 standard deviations. The gaps favoring boys cluster in the wealthiest districts — which is a fact about culture, not about arithmetic.

Reardon, Fahle, Kalogrides, Podolsky & Zárate, American Educational Research Journal, 2019

127,346

More girls than boys took AP Statistics

In 2024, 127,346 girls sat AP Statistics compared with 123,695 boys, and AP Calculus AB was close to even at 46.2% female. Girls are not opting out of hard math at the top of high school.

College Board, AP Program Summary Report, 2024

Grade 1

Teachers rate girls lower for the same work

In two nationally representative kindergarten cohorts collected twelve years apart, teachers rated girls' math ability below that of boys who behaved identically and scored identically. It shows up by first grade and it does not go away.

Cimpian, Lubienski, Timmer, Makowski & Miller, AERA Open, 2016

9.3 vs −7.3

Grading bias changes who takes advanced math

When teachers' grades are compared against blind external exams, pro-boy grading bias raises a boy's chance of completing advanced math by 9.3 percentage points and lowers a girl's by 7.3. The finding replicated in a second country.

Lavy & Sand, Journal of Public Economics, 2018; Lavy & Megalokonomou, AEJ: Applied Economics, 2023

Age 6

The stereotype arrives before the gap does

At age five, children do not associate brilliance with men. At age six they do — and six-year-old girls already start avoiding games described as being for children who are “really, really smart.” The belief shows up years before any measurable difference in performance.

Bian, Leslie & Cimpian, Science, 2017

+0.29

Girls get better math grades than boys who tested the same

Across 9,585 ninth-graders, girls earned math grades 0.29 grade points higher than boys with no difference in prior test scores — and the advantage survived controls for preparation and behavior. They are doing the work.

Sartain, Freire, Easton & Diaz, EdWorkingPaper AI23-707, 2023

42% vs 22%

The field with the least math is the most male

Women earn 42% of US bachelor's degrees in mathematics and statistics — but only about 22% in computer science. If the barrier were mathematical ability, those numbers would not be the wrong way around.

NCES Digest of Education Statistics; NSF NCSES, NSB-2023-32

53.9% vs 8.0%

Same math, opposite gender balance

Women are 53.9% of operations research analysts and 8.0% of computer network architects. Both jobs are mathematically demanding. The gradient across occupations tracks culture and welcome, not mathematical load.

Six things an adult in Hansford County can do this week

  1. 1. Never say “I was bad at math either”

    It is meant as comfort and it lands as permission. It tells a girl that quitting is what people like her do, and it comes most often from the adults she trusts most.

  2. 2. Praise the method, not the girl

    “You kept going after it broke” builds something. “You're so smart” makes the next hard problem a threat to her identity, and the safest move becomes not trying.

  3. 3. Check the grade against the test

    The research finds grading bias by comparing teacher grades to blind external scores. You can do the same thing for one child: if her grades sit below her test scores, ask why, in writing, and keep the answer.

  4. 4. Put her in the room where the math is hard

    Advanced placement is often a recommendation, and recommendations carry bias. Ask directly what it takes to be placed in the harder class, then ask for the placement.

  5. 5. Show her a real one

    Not a poster. A person — an engineer, an analyst, a nurse doing dosage math, a surveyor. A woman doing math for a living, in the room, answering questions.

  6. 6. Write the sentence down when someone says it

    The teacher in this story said one sentence and it lasted a lifetime. If someone says a version of it to your daughter, write it down with the date. It stops being a feeling and becomes a record.

Hansford County is one of 254 counties in Texas. Every one of them has a school board, and every school board takes public comment.
