The instructor didn’t reply, and docked Ostovitz’s grade.
Ostovitz’s mother, Stephanie Rizk, says her daughter is a high-achieving pupil who cares about doing nicely in class and she or he was alarmed when the instructor jumped to conclusions about Ostovitz’s work so early within the faculty yr.
“Get to know their level of skill, and then maybe your AI detector is useful,” Rizk says.
Rizk instructed NPR she met with the instructor in mid-November and the instructor mentioned they by no means noticed her daughter’s message.

The college district, Prince George’s County Public Faculties, made clear in an announcement that Ostovitz’s instructor used an AI detection software on their very own and that the district doesn’t pay for this software program.
“During staff training, we advise educators not to rely on such tools, as multiple sources have documented their potential inaccuracies and inconsistencies,” the assertion mentioned.
PGCPS declined to make Ostovitz’s instructor accessible for an interview. Rizk instructed NPR that after their assembly, the instructor not believed Ostovitz used AI.
However what occurred to Ostovitz isn’t shocking.
Greater than 40% of surveyed Sixth- to Twelfth-grade academics used AI detection instruments over the last faculty yr, in accordance with a nationally consultant ballot by the Heart for Democracy and Know-how, a nonprofit that advocates for civil rights and civil liberties within the digital age.
That’s regardless of quite a few analysis research exhibiting that AI detection instruments are removed from dependable.
“It’s now fairly well established in the academic integrity field that these tools are not fit for purpose,” says Mike Perkins, a number one researcher on tutorial integrity and AI at British College Vietnam.
Perkins discovered that among the hottest AI detectors — together with Turnitin, GPTZero and Copyleaks — flagged some issues as AI that weren’t, and vice versa. Their accuracy charges dropped even additional when AI textual content was manipulated to seem extra human.
“We saw some really concerning problems with some of the most prolific AI text detection tools,” he says.
Regardless of these issues, NPR discovered that college districts from Utah to Ohio to Alabama are spending 1000’s of {dollars} on these instruments.
Why one of many nation’s largest districts makes use of AI detection software program
Close to Miami, Broward County Public Faculties is spending greater than $550,000 on a three-year contract with Turnitin. The long-standing ed-tech firm has traditionally supplied faculties with plagiarism detection software program; in 2023, it launched an AI detection function. When educators put pupil work via this software, it generates a proportion, which displays the quantity of textual content the software program determines was doubtless generated by AI. One caveat: In line with the corporate, scores of 20% or decrease are much less dependable.
“The Turnitin tool is something that helps us facilitate conversation and feedback, not grading,” says Sherri Wilson, director of modern studying for the Broward faculty district, which enrolls greater than 230,000 college students and is among the largest faculty districts within the nation.
Wilson says the district is “totally aware” of the analysis exhibiting AI detection instruments, together with Turnitin, aren’t 100% correct or dependable.
Turnitin additionally acknowledges this: On the corporate’s web site, it says, “our AI writing detection may not always be accurate … so it should not be used as the sole basis for adverse actions against a student.”
Turnitin wrote in an announcement to NPR that it’s extra necessary to keep away from falsely accusing college students of dishonest than to catch all AI writing.
Wilson says the Turnitin software remains to be precious as a result of it saves academics time by shortly scanning pupil work for suspected AI use.
Another excuse that Broward academics have entry to the software, Wilson says, is that the district participates in tutorial packages, reminiscent of Worldwide Baccalaureate, or IB, by which pupil work should be authenticated by academics earlier than it’s despatched out for exterior overview.
Each of the packages Broward affords, IB and Worldwide Schooling at Cambridge, instructed NPR that faculties aren’t required to make use of AI detection software program as a part of the authentication course of. Nonetheless, Broward instructed NPR in an announcement, “we have chosen to provide our teachers with [Turnitin] as one of the tools to meet the requirements.”
However Wilson says academics are the last word authority on whether or not a pupil’s work is their very own — not the AI detection software.
“They’re using these tools as feedback to then have those teachable moments with students,” she says.
Why one instructor makes use of AI detection instruments
Language and literature instructor John Grady says, for him, AI detection instruments present “a jumping off point” to begin a dialog with a pupil who might have used AI.
Shaker Heights Excessive Faculty instructor John Grady says he places all pupil essays via GPTZero – however it isn’t the one software he depends on to find out if a pupil’s work is their very own. (Dustin Franz for NPR)
“It’s certainly not foolproof,” he says. “But it gives you something to hang your hat on.”
Grady teaches at Shaker Heights Excessive Faculty, a part of the Shaker Heights Metropolis Faculty District exterior Cleveland. The district serves roughly 4,400 college students, and is paying GPTZero, one other AI detection software program firm, about $5,600 this yr for annual licenses for 27 of the district’s academics. The software calculates a proportion chance {that a} pupil’s work is AI-generated.
Grady says he places all pupil essays via GPTZero; if the software exhibits greater than a 50% chance AI was used for the project, Grady digs deeper. That features utilizing revision historical past instruments to see how a lot time a pupil spent on an project, and what number of edits they made throughout the writing course of. If it seems that a pupil made only some edits and spent hardly any time writing, he’ll test in with that pupil.
“And I’ll say, ‘Hey, this flagged. Can you talk to me about why?’ I’d say the bulk of the time, like 75%, if it was AI, they’d be like, ‘Yeah, I did.’ And I’m like, ‘OK, well now you’ve got to rewrite it with less credit,’” Grady says.
Edward Tian, co-founder and CEO of GPTZero, says that is how educators needs to be utilizing his firm’s software.
“We definitely don’t believe this is a punishment tool,” Tian says. “This needs to be a tool in the toolkit and not the final smoking gun.”
He says it’s necessary to grasp {that a} GPTZero likelihood rating underneath 50% means it’s extra doubtless the textual content was human versus AI-generated. He says scores over 50% warrant nearer examination — like what Grady describes.
Tian doesn’t dispute the analysis that exhibits GPTZero isn’t all the time dependable. However he notes that there are educators, like Grady, who nonetheless discover it precious for the data it offers.
He says that instruments like his supply a “signal on what’s happening in your classroom” however that academics ought to all the time comply with up with college students if that sign exhibits one thing regarding.
The AI detection skeptics
Shaker Heights junior Zi Shi, whose first language is Mandarin, says his writing fashion can typically appear like AI “because of the repetition of words I use. I feel like it’s because of how limited my vocabulary is.”
Shi — who isn’t a pupil of Grady’s — says he’s nonetheless engaged on his writing abilities and he’s involved that AI detection software program could be biased towards non-native English audio system like himself.
Some educators share this concern, although the analysis thus far is proscribed and contradictory.
Shi says an project he accomplished for his English class earlier this fall was flagged by GPTZero as probably AI-generated. He says his instructor steered that his use of a web-based software referred to as Grammarly might have triggered the detection software program. Grammarly makes use of AI to right grammar and, if prompted, generate textual content. (The instructor confirmed Shi’s account with NPR.)
Shi says he solely used Grammarly to wash up his writing and that he wrote the project himself. “It was definitely disappointing to see the comment of it being flagged as AI,” Shi says.
Shi thinks AI detectors needs to be regarded as a “smoke alarm, where it’s a sign, or warning. But, you know, sometimes it could be like a false alarm.”
He questions whether or not the college district needs to be spending 1000’s of {dollars} on AI detection software program. He says that cash could possibly be higher spent on skilled growth for academics.
Carrie Cofer, a highschool English instructor within the Cleveland Metropolitan Faculty District — only a few miles from Shaker Heights — shares that view.
Final yr, as an experiment, she uploaded a chapter of her Ph.D. dissertation into GPTZero. “And it came up with like 89% or 91% AI-written, and I’m like, ‘Oh, no, I don’t think that’s right, because it was all mine,’” Cofer says.
In Cleveland, English instructor Carrie Cofer says educators might want to adapt to AI by altering how they educate and assess pupil studying. (Dustin Franz for NPR)
Cofer helps her district form its AI coverage and tips; she says Cleveland faculties don’t at present pay for AI detection software program and she or he’d advocate towards it.
“I don’t think it’s an efficacious use of their money,” Cofer says. “The kids are going to get around it one way or the other.”
Some workarounds that college students may flip to incorporate utilizing AI detection software program themselves, to workshop assignments in order that they don’t get flagged, and utilizing “AI humanizer” packages, which declare to make AI-generated writing seem extra human.
In the end, she says, academics might want to adapt to AI by altering how they educate and assess pupil studying.
Again in Maryland, highschool junior Ailsa Ostovitz can also be adapting. She now runs all her homework assignments via a number of AI detection instruments earlier than she turns them in.
The writing is her personal, she says, however she’ll rewrite sentences the software program identifies as probably AI-generated, an additional step that provides about half an hour to each project.
“I think I’ve definitely become more vigilant about presenting my work as mine and not AI,” she explains.
She doesn’t need to take any possibilities.
