Google AI Mode Homework Test: Every Assignment Done, Always On
Google AI Mode homework test: it completed every assignment, nobody can switch it off, and 11- and 15-year-olds got the same product. What still works.
Blocking ChatGPT used to feel like a homework plan. It is not anymore. In a July 2026 test, Google Search’s AI Mode completed every homework assignment it was given, and no parent, school administrator or student can turn it off. That is the Google AI Mode homework problem in two sentences: the AI that writes the essay is now inside the search box every child already uses, including on school Chromebooks.
The finding comes from Common Sense Media’s Youth AI Safety Institute, which rated Google’s AI Overview and AI Mode “Unacceptable Risk.” The homework result is only one part of that report, but it is the part that changes daily life in most homes. Here is what the testers found, why AI in search is different from a chatbot, and what still works when you cannot flip a switch.
Key Takeaways
- AI Mode completed 100% of homework assignments in the Institute’s test, which ran 180 homework interactions across AI Overview and AI Mode on child and teen accounts.
- Neither feature can be disabled by parents, school administrators or students, unlike Google’s separate Gemini chatbot, which schools can restrict.
- An 11-year-old and a 15-year-old got the same product. The Institute found no meaningful difference between the supervised child account and the teen account.
- Learning suffers when AI does the work. A 2025 field experiment in PNAS found unrestricted GPT-4 access raised practice grades 48% but cut later exam grades 17%; a tutor version with guardrails avoided most of that harm.
- What still works is human: assignments that require process, explanation at the kitchen table, and clear family rules about when AI help is allowed.
What the Google AI Mode homework test found
The Google Search risk assessment ran from May 19 to July 1, 2026, on accounts managed through Google Family Link: a supervised 11-year-old and a 15-year-old teen account without active supervision, both with SafeSearch on. Researchers ran seven test plans totaling more than 2,600 interactions, plus an analysis of over 2,100 citations. The homework plan, math problem sets and humanities essays, accounted for 180 interactions across the two AI features.
The core homework finding is blunt: “AI Mode completes 100% of homework assignments. Because schools cannot restrict AI Mode on devices that access Google Search, students using school-issued hardware have access to an AI assistant that does the work for them.”
The Institute’s recommendations make the gap clear. It asked Google to turn AI Search features off by default for accounts it knows belong to minors and for Google Workspace for Education accounts, to add them to the school admin console, and to give parents controls in Family Link “equivalent to existing Gemini controls.” When a student account’s search looks like a request to complete homework, it asked Google to redirect toward learning support instead of submittable work.
Two AI features, neither optional
Google Search now has two AI layers, according to the report:
- AI Overview appears automatically at the top of most results. Users can scroll past it but “cannot turn it off.”
- AI Mode is a chatbot-style conversation inside Search, reached by clicking. Attaching a photo or file to any search switches into it automatically, and since May 2026 an “Ask Anything” box under each AI Overview leads straight into it.
That last detail matters for homework. A student can photograph a worksheet, attach it to a search, and land in AI Mode without ever opening a chatbot.
Same answers at 11 and 15
“We found no meaningful differences in product behavior between accounts associated with the 11-year-old and 15-year-old test accounts,” the Institute wrote. SafeSearch, which filters explicit content, is on by default for under-18 users. But the AI features themselves offer a single experience for everyone under 18. Google’s standalone Gemini chatbot is different: parents must actively enable it for children under 13, and schools can restrict it.
Why AI in search changes the homework problem
A search engine used to return links. The child still had to read, choose, take notes and write. AI Overview and AI Mode do the reading and writing step, using the same retrieval-and-summary method as other “answer engines”: search the web, pull text from pages, have a language model compose a response with citations.
Three consequences follow for families.
Blocking chatbots no longer blocks AI homework help. The most common rule families set, “no ChatGPT for homework,” does not touch Google Search. And school-issued devices, which can block chatbot sites, cannot block AI features built into Search.
The answer looks like research. AI responses come with citations and a confident format. The Institute found nearly a third of cited sources were forums and social posts, “formatted identically to peer-reviewed research,” and that AI Overview rejected false premises only about half the time. A child who has not learned to evaluate sources has no signal to doubt it.
The work is easier to hide. A polished paragraph from Search looks the same as one from a chatbot, and teachers cannot see which tool produced it.
Our breakdown of how Perplexity handled the same tests shows that switching to a different AI search engine does not solve this either.
What the learning research says
Does it matter if AI does the homework, as long as the student reads the answer? The best evidence says yes, with an important twist.
In a field experiment published in PNAS in 2025, Hamsa Bastani and colleagues gave nearly 1,000 high school math students access to GPT-4 through two interfaces: a standard ChatGPT-style one (“GPT Base”) and a tutor version designed to give hints instead of answers (“GPT Tutor”). While students had access, practice grades rose 48% with GPT Base and 127% with GPT Tutor. But when access was removed for the exam, the GPT Base group scored 17% lower than students who never had AI. The tutor version “largely mitigated” that harm. The authors’ summary: without guardrails, students “use GPT-4 as a ‘crutch’” and then perform worse on their own.
| Situation | Practice performance | Later performance on their own |
|---|---|---|
| No AI access | Baseline | Baseline |
| AI that gives answers (GPT Base) | 48% higher | 17% lower |
| AI tutor with guardrails (GPT Tutor) | 127% higher | Harm largely avoided |
Source: Bastani et al., PNAS, 2025. One study, one subject, one country; the pattern, not the exact numbers, is the lesson.
The Institute’s finding fits that pattern. AI Mode behaves like GPT Base: it gives the answer. And unlike GPT Tutor, nothing in Search switches a student account into hint mode.
What still works when you cannot switch it off
Move the check from the answer to the explanation
If AI can produce the answer, the answer stops being proof of learning. Ask your child to explain one problem out loud, or to tell you how they would start the essay without notes. Two minutes at the kitchen table shows more than any detector.
Set a family rule on when AI help is allowed
A workable rule many families use: AI search is fine for finding sources and checking a fact, not for producing work that gets turned in. Write it down, and agree what happens if it is broken. Our guide to how homework is being redesigned in the AI era covers how teachers are adapting.
Ask the school what it is changing
Since schools cannot turn AI Mode off, the useful question is how assignments are changing: more in-class writing, drafts, oral defenses, process notes. Our piece on the AI-proof homework teachers assign now has examples you can mention at a parent meeting.
Teach the citation habit
Before trusting any AI summary, open the cited page and find the sentence. If it is a forum, the claim is unverified. This is the one skill that protects your child across every AI tool.
What not to do: rely on a block or a detector
You cannot block AI Mode, and a detector cannot tell you whether your child learned anything. Neither replaces a conversation about why the work matters.
What to Watch For Over the Next 3 Months
- Week 4: Whether Google adds AI Search controls to Family Link or the Workspace for Education admin console, as the Institute requested.
- Month 2 red flags: Homework that is finished unusually fast, reads more polished than your child’s speech, or that your child cannot explain.
- Month 3 self-check: Can your child describe the difference between using AI to find sources and using it to do the assignment?
Frequently Asked Questions
Can I turn off Google AI Mode for my child?
No. The Institute found that neither AI Overview nor AI Mode can be disabled by parents, school administrators or users. SafeSearch, which filters explicit content, is on by default for under-18 accounts, but it does not turn off the AI features. Google’s separate Gemini app does have parent and school controls.
Can schools block AI Mode on Chromebooks?
Not as of the July 2026 assessment. Schools can restrict the standalone Gemini chatbot, but AI Overview and AI Mode are built into Google Search, and the Institute said schools cannot restrict AI Mode on devices that access Search. It asked Google to add these features to the education admin console.
Did AI Mode really do all the homework?
In the Institute’s test, yes: “AI Mode completes 100% of homework assignments.” The homework plan ran 180 interactions across AI Overview and AI Mode, using math problem sets and humanities essays on 11- and 15-year-old accounts. It is one test plan, from US accounts, in mid-2026.
Is using AI for homework always bad?
No. The 2025 PNAS study found an AI tutor that gives hints rather than answers raised practice performance without harming later exam results. The harm came from AI that simply supplied answers. The question is whether the tool makes your child think or thinks for them.
What should I say to my child about this?
Be direct: the answer is now easy to get, so the answer is not the point. What matters is whether they can do it themselves on the test, at the next grade level, and in a job. Agree together when AI help is fine and when it is not.
