How Many Teachers Use AI?

AI in classrooms isn't coming. It's already here. And more teachers are jumping on board faster than ever before.

The bottom line? Somewhere between 60-85% of public school teachers in the U.S. used AI tools during the 2024-2025 school year. That's a massive jump from just a couple years ago when about a third were using artificial intelligence in their work.

The Exact Numbers: How Many Teachers Use AI?

Let's start with what you came here for - the actual numbers.

Out of approximately 3.7 million public school teachers in the United States, roughly 2.2 to 3.1 million teachers are now using AI tools in their work. That's based on survey findings showing 60-85% adoption rates during the 2024-2025 school year.

Here's what that looks like broken down by survey source:

Globally, the picture is even bigger. The OECD surveyed 280,000 teachers across 55 countries and found that 36-41% use AI, meaning tens of millions of educators worldwide are now incorporating artificial intelligence into their classrooms.

U.S. Teachers: The Detailed Numbers

Walton Family Foundation & Gallup Survey (Spring 2025)

The Walton Family Foundation and Gallup study surveyed 2,232 public school teachers and is one of the most comprehensive studies available.

The coolest finding? Teachers who use AI weekly save about 6 hours per week on work tasks. Over a whole school year, that adds up to roughly 6 extra weeks of time. AI saves teachers from drowning in busywork so they can focus on what matters, actual teaching and student learning.

Weekly users also reported that AI improves the quality of their work. About 64% said it helps them create better student materials adapted to meet student needs.

Center for Democracy & Technology Survey (Summer 2025)

The CDT survey talked to 806 middle and high school teachers and found even higher adoption:

• 85% of teachers (approximately 3.1 million nationally) used AI during 2024-2025
• 57% used generative AI tools to help write IEPs for students with disabilities
• Teachers reported using AI for curriculum development (69%), student engagement (50%), and grading tools (45%)

However, seven in ten teachers worry that AI weakens critical thinking and other important skills that students need to learn.

RAND Corporation (2025)

RAND's research found that 53% of English language arts, math teachers, and science teachers used AI for school. That's an increase of more than 15 percentage points from the past school year.

But here's the catch: only 34% of teachers said their school district actually has policies about AI use. So most educators are figuring it out on their own without much guidance from education leaders.

This Happened FAST

EdWeek's surveys show how fast forward things changed:

That means roughly 1 million more teachers started using AI between 2024 and 2025. This was the year generative AI use in teaching exploded. More teachers started experimenting, and many found real value in these tools.

What Are Teachers Actually Using AI For?

Here's how teachers use AI tools, ranked by monthly usage from the Walton Family Foundation survey:

1. Creating lesson plans - 37% (~1.37 million teachers)
2. Making worksheets and activities - 33% (~1.22 million)
3. Modifying materials for different student needs - 28% (~1.04 million)
4. Administrative work - 28% (~1.04 million)
5. Developing assessments - 25% (~925,000)
6. Grading and student feedback - 16% (~592,000)
7. One-on-one instruction - 14% (~518,000)
8. Analyzing student data - 12% (~444,000)

Teachers working with AI mostly use it for prep work and saving time on administrative tasks, not replacing human interaction in the classroom. About half of teachers who use AI say it helps them provide better student feedback and create more personalized learning environments.

Around the World: Global Numbers

The OECD did a massive survey called TALIS 2024, covering 280,000 teachers from 55 countries. According to Education International's analysis:

Singapore and the UAE are way ahead compared to other countries. Why? They've invested heavily in professional development, 76% of Singapore teachers received AI training, compared to just 9% in France. There's a strong connection between teachers who receive training and teachers who actually use AI regularly.

Out of teachers who use artificial intelligence, the most common uses are to efficiently learn about topics (68%) and generate lesson plans (64%). The least common is using AI for grading (26%) and reviewing student data (25%).

Higher Education: A Different Story

University faculty are actually behind K-12 educators when it comes to AI adoption. According to the Digital Education Council's faculty survey (which surveyed 1,681 faculty members from 52 institutions across 28 countries) and Cengage's 2024 report:

• 61% of faculty have used AI in teaching
• But 88% use it only minimally
• 45% of higher education faculty used generative AI tools
• 93% say they plan to expand use of AI in the next two years
• Graduate students and younger faculty have higher adoption rates

UNESCO's 2025 survey of 400 institutions across 90 countries found that nine in ten faculty reported using AI tools in their professional work, mostly for research and writing. About half are experimenting with AI in teaching, including lesson planning and grading support.

The Training Problem

Here's where things get tricky. Many teachers are using AI but haven't been trained on it. From EdWeek's research and RAND data:

The NEA Task Force report emphasized that educators need more training to teach with AI and teach about AI. Building AI literacy and AI knowledge among teachers remains a major challenge for schools nationwide.

Meanwhile, in Singapore, 76% of teachers have been trained. That's probably why their usage rates are so much higher. There's a clear lesson here: when school districts invest in professional development, more teachers actually use AI effectively.

How Teachers Feel About AI

It's a mixed bag. From the World Economic Forum report, Microsoft's 2025 study, and various education statistics:

The Good:

• 71% of teachers (~2.63 million) think AI will be essential for future success
• 57% believe AI can improve accessibility for students with disabilities
• 65% of special education teachers are especially optimistic about improving student outcomes
• Teachers who use AI more tend to feel more positive about it
• AI can support adaptive learning platforms and tools like Khan Academy

The Concerns:

• 70% (~2.59 million teachers) worry AI weakens important skills students need
• 57% think AI decreases independent thinking and problem solving
• 52% worry about critical thinking going down
• 28% (~1.04 million) oppose AI in K-12 schools entirely
• Concerns about data privacy and student use without proper guidance

Teachers see benefits for student engagement but are genuinely worried about kids becoming too dependent on AI in their daily life. Many educators want more training before they feel confident using these tools to teach and help students learn effectively.

Quick Stats Recap

The Bottom Line

The data is clear: artificial intelligence is transforming how teachers work. Between 2.2 and 3.1 million public school teachers in the U.S. alone now use AI tools, primarily for creating lesson plans, making worksheets, and handling administrative work. Teachers who use AI weekly save time, about 6 hours per week, which they can reinvest in student learning and improving student engagement.

But there's still a major gap. Over 2 million teachers want more training and clearer guidance from their school district. Education leaders need to invest in professional development so educators can use AI effectively and responsibly. The countries seeing the best results, like Singapore, are the ones where trained teachers far outnumber those learning on their own.

As generative AI tools become more common in schools, the question isn't whether teachers will use them. It's whether they'll get the support they need to use them well.

TL;DR: Between 2.2 and 3.1 million U.S. teachers now use AI tools. Around 60-85% of public school teachers used AI during 2024-2025. Teachers who use AI weekly save about 6 hours per week. Usage basically doubled in the last year. But over 2 million teachers still haven't received any AI training - and that's the biggest challenge education leaders need to solve.
