The Gates Foundation announced a $400 million commitment this week to bring AI tutoring tools to schools across the United States and internationally, but educators are raising urgent concerns about whether the investment will actually help students or widen existing inequalities. The funding is part of a broader $1 billion Gates Foundation initiative, with 40 percent dedicated to education, aimed at helping 10 million more Americans earn credentials of value by 2045.

The timing of this massive investment is striking because it comes as skepticism about classroom technology is growing. Research shows that since the U.S. spent $30 billion swapping textbooks for laptops, test scores have dropped among some students, and Gen Z has demonstrated lower cognitive capabilities than previous generations, according to neuroscientist Jared Cooney Horvath in testimony to the U.S. Senate Committee on Commerce earlier this year. Meanwhile, New York City announced a one-year moratorium on student-facing generative AI for students in grades 2 through 8, affecting roughly 600,000 students, or about two-thirds of the system.

What Are Teachers' Main Concerns About AI in Classrooms?

Teachers who work directly with students have identified several critical gaps that money alone cannot solve. The most pressing issue is that schools cannot simply hand over AI tools and expect them to work. Educators need time, training, and ongoing support to use the technology effectively, and many under-resourced schools lack all three.

Beyond implementation challenges, teachers worry about who actually benefits from AI tutoring. Students who struggle the most may also be the least equipped to recognize when AI provides inaccurate or incomplete information. As one history teacher explained, those without strong foundational knowledge are more likely to accept AI responses at face value without questioning them.

"I still need to check its accuracy, decide whether it supports the learning objective, and make sure it provides the right level of challenge for my students. AI can support teacher expertise, but it cannot replace it," said Siobhan Casey, principal of Crimson Global Academy's Greenwich Campus.

Another educator at a special education school in Florida raised a concern that cuts to the heart of equity: the students who need the most help may also need the most adult guidance in learning how to use AI effectively. Technology can be a powerful equalizer, but only if access to the tool translates into access to quality education.

How Can Schools Successfully Implement AI Tools?

• Pair Technology With Teacher Training: The Gates Foundation spokesperson told Fortune that tools will be tested in schools serving high shares of low-income students and paired with comprehensive teacher training before being scaled to more schools.
• Evaluate With Independent Researchers: The foundation plans to have outside researchers, including a Johns Hopkins study, examine whether early results hold across different schools and whether students who have fallen behind actually catch up.
• Focus on Foundational Skills First: Schools may need to prioritize fixing literacy and numeracy before introducing AI tools, according to edtech industry leaders, since students cannot benefit from advanced technology if they lack basic reading and math skills.
• Measure Success Carefully: Rather than raising overall test scores, success should be measured by whether students who have fallen behind actually catch up, the Gates Foundation spokesperson explained.

The Gates Foundation argues that its investment is addressing a fundamental market failure. Without philanthropic intervention, the most capable AI tools will be built first for wealthy institutions and individuals who can afford them, not for those who could benefit most. However, some in the edtech industry question whether lower-resourced schools can actually absorb such an investment effectively.

"The schools this money is meant to reach are some of the least able to absorb it for its desired purpose. They often tell me they have to fix literacy and numeracy first, and they're not necessarily wrong, but it does mean that the districts moving fastest are best placed to use the money," said Dora Palfi, CEO and cofounder of edtech platform Imagi.

Palfi added a warning that echoes across the education sector: the exact funding made to close a divide could end up widening it.

Where Has AI Actually Helped in Classrooms?

Despite the concerns, some teachers have found genuine value in AI tools when implemented thoughtfully. In special education settings, AI has given students another way to ask questions, receive explanations in different formats, or work through material at their own pace. For teachers, the technology has saved time on administrative tasks like creating materials and adapting lessons, freeing up more time for actual instruction.

"The biggest change wasn't that AI started doing the teaching. It gave me more time to teach," said Amy McBride, a teacher at Pepin Academies, a special education school in Pasco County, Florida.

The Gates Foundation's strategy acknowledges that too many tools have been adopted without evidence they work, and the foundation insists that teachers must remain central to any implementation. The foundation's approach includes testing in schools serving high shares of low-income students, pairing tools with teacher training, and having independent researchers evaluate results before scaling.

As schools navigate this critical moment, the question is not whether AI belongs in education, but how to ensure that when it arrives, it actually serves the students who need it most. The $400 million investment will test whether careful implementation, teacher support, and rigorous evaluation can deliver on AI's promise, or whether it will become another expensive technology that widens rather than closes the achievement gap.
