ChromeOS now powers more than 38 million Chromebooks deployed in K-12 schools worldwide, and 60.1% of all student devices sold globally in 2025 ran the operating system. This article reports verified data on ChromeOS accessibility feature deployment, ChromeVox screen reader market position, and the disability population using these tools across 2024 and 2025.
ChromeOS Accessibility Statistics: Top 5 Numbers
- Chromebooks held 60.1% of the global K-12 device market in 2025.
- 93% of US school districts planned Chromebook purchases in 2025, up from 84% in 2023.
- ChromeVox reached 3.8% primary screen reader share in the WebAIM 2024 survey of 1,539 users.
- 14% of US public school students received special education services in 2024, equating to roughly 6.7 million Chromebook users with accommodations.
- Google Workspace for Education served more than 150 million students and educators by late 2025.
How Many People Use ChromeOS Accessibility Features in Schools?
Google does not publish per-feature activation rates for ChromeOS accessibility tools. The closest verified figure comes from K-12 deployment data, where Chromebooks dominate global student computing.
About 38 million Chromebooks were active in K-12 schools worldwide in 2024, and the platform held 60.1% of the global student device market in 2025.
| Metric | Figure | Year |
|---|---|---|
| Global K-12 device market share | 60.1% | 2025 |
| US school districts planning purchases | 93% | 2025 |
| US school districts planning purchases | 84% | 2023 |
| Chromebooks deployed in K-12 worldwide | 38 million+ | 2024 |
| Workspace for Education users | 150 million+ | Late 2025 |
| ChromeOS US desktop share | 8.44% | 2025 |
| ChromeOS global desktop share | 1.86% | 2025 |

The US share runs 4.5 times higher than the global average, which means American classrooms drive most of the accessibility feature usage even though Chromebooks remain a minority desktop platform globally.
Special Education Users on Chromebooks
Applying the 14% US special education rate to the 48.1 million public school student population gives an estimated 6.7 million students with formal IEP or 504 accommodations who likely use a Chromebook for learning. School accessibility trends data places this group as the single largest accessibility audience on the platform.
ChromeVox Screen Reader Market Share
The WebAIM Screen Reader User Survey 10, conducted in December 2023 and January 2024 with 1,539 respondents, is the only independent dataset measuring ChromeVox adoption against competitors.
ChromeVox reached 3.8% primary desktop usage. JAWS led at 40.5%, followed by NVDA at 37.7% and Apple VoiceOver at 9.7%.
| Screen Reader | Primary Desktop Share | Commonly Used |
|---|---|---|
| JAWS | 40.5% | 60.5% |
| NVDA | 37.7% | 65.6% |
| VoiceOver (Apple) | 9.7% | 43.5% |
| ChromeVox | 3.8% | — |
| Other screen readers | ~8.3% | — |
Source: WebAIM Screen Reader User Survey 10, February 2024 (n=1,539).
ChromeVox runs only inside ChromeOS, so its ceiling is the installed base of the operating system. JAWS and NVDA work across Windows machines, which gives them broader access to the professional screen reader market.
Survey respondents skewed toward adult professional users, while ChromeVox sits mostly with K-12 students who rarely appear in voluntary accessibility surveys. ChromeVox feature documentation covers the tool’s full capability set.
Multi-Reader Usage Among Survey Respondents
The 2024 WebAIM data showed 71.6% of users run more than one screen reader, and 43% use three or more. Mobile screen reader use reached 91.3%, with VoiceOver leading mobile at 70.6%.
ChromeOS Accessibility Feature Updates 2024–2025
Google added several built-in accessibility tools across ChromeOS M132 through M137. The most notable addition is Face Control, which enables hands-free operation through facial gestures.
| Feature | Update Period | User Group |
|---|---|---|
| Face Control | ChromeOS M132+, early 2025 | Motor impairment |
| ChromeVox + Braille captions | Updated 2025 | Deafblind users |
| Reading Mode with natural TTS | Expanded 2024 | Dyslexia, low vision |
| Select-to-Speak voices | Updated 2024 | Low vision, language learners |
| Voice Dictation | Expanded 2024 | Motor impairment |
| Chromebook Plus accessibility button | 2024 | All users |
| College Board Bluebook integration | 2025 | SAT and AP test takers |
| Image descriptions in ChromeVox | Maintained, 17 languages | Visual impairment |

Face Control matters because comparable software on Windows or macOS typically costs hundreds of dollars per license. Google packaged the same capability into ChromeOS for free.
The College Board Bluebook integration in 2025 gave ChromeVox formal status in standardized testing. Students taking the SAT, PSAT, or most AP exams can now use ChromeVox and Select-to-Speak inside the official testing app, which makes ChromeOS the most documented accessibility platform for US college admissions testing.
ChromeOS Accessibility Feature Audience Size
The World Health Organization estimates 1 in 6 people globally experience some form of disability. Applied to Workspace for Education’s 150 million users, that gives roughly 25 million potential accessibility feature users in education alone.
| Population Metric | Figure | Scope |
|---|---|---|
| Global disability prevalence | 1 in 6 (~1.3 billion) | Worldwide |
| US K-12 special education rate | 14% | US public schools |
| Implied US Chromebook special ed users | ~6.7 million | US K-12 |
| Workspace for Education users | 150 million+ | Global |
| Potential education accessibility audience | ~25 million | Global, calculated |
| US IDEA Part B federal funding FY2024 | $14.7 billion | US federal |

The 25 million figure is a ceiling based on prevalence rates. Actual feature activation runs lower because not every student with a disability requires assistive software, and Google has not released usage telemetry. Special education deployment data tracks the distribution of these tools in district settings.
Enterprise and District Management Tools
Google’s Admin console includes 15 enterprise accessibility policies that let IT teams configure ChromeVox, Dictation, High Contrast, and other tools per device or per organizational unit. Enterprise accessibility controls reference documents the full policy list available to administrators.
ChromeOS vs Other Accessibility Platforms
The platform comparison shifts depending on the user group measured. Among adult professional screen reader users surveyed by WebAIM, Windows tools dominate. Among K-12 students with accommodations, ChromeOS is the default.
Google’s December 2024 education review framed ChromeOS accessibility as a substitute for paid third-party assistive technology. Schools using built-in voice dictation, Select-to-Speak, and Reading Mode can avoid licensing costs for software that previously came as separate purchases. Free accessibility tools coverage details the cost savings reported by districts.
