According to OpenAI, ChatGPT is only allowed from age 13, and under 18 only with a parent's permission. Study mode, parental controls and teen mode are aimed at teenagers and adults, not at elementary school kids. For grades 1 to 4 that means: no account of their own, you are the only one who uses ChatGPT at most, and the answer in the notebook is always written by the child.

On Reddit, someone writes about their niece: "My niece (10) already uses ChatGPT for homework now and then and I wonder whether that's a problem, an opportunity or just the new reality." (r/Eltern (in German)) This article answers the question as of September 2026: what OpenAI allows, what study mode, parental controls and teen mode can do, and which rules make sense for elementary school kids.

How old do you have to be to use ChatGPT?

The rule is in OpenAI's Terms of Use for Europe (version of January 16, 2026): anyone who uses ChatGPT must be at least 13 years old or have reached the minimum age for consent in their country. Anyone under 18 needs a parent's permission and is supposed to read the terms together with them. So an elementary school child is not allowed to use ChatGPT on their own. That is not our recommendation, it is the provider's rule.

According to OpenAI, anyone who gives an age between 13 and 17 when signing up, or whom OpenAI's age estimation judges to be a minor, automatically lands in the teen version. The estimate is not flawless: according to OpenAI, even the most advanced systems sometimes struggle to estimate age correctly.

Google is similar: according to the Gemini Help (in German), Gemini with a personal Google account requires a minimum age of 13 or the minimum age that applies in the respective country, and according to the Google Families Help (in German), Gemini is not available for child accounts with parental supervision in the European Economic Area and Switzerland.

What “from 13” means for you

Your elementary school child does not get a ChatGPT account of their own. If ChatGPT plays a role at home, it is you who asks and then explains things to your child. Parental controls only become important once your child is 13 and gets an account of their own with your permission.

What ChatGPT offers families today

Since summer 2025, OpenAI has introduced several features for school and family. The overview is our own compilation: what the features can do according to the provider, and which of them apply to an elementary school child.

As of September 2026. The basis is the information from OpenAI on openai.com and in the Help Center (linked in the text and under Sources).

Parental controls. Since September 29, 2025, you can link your account to your teenager's account. You then set quiet hours during which ChatGPT cannot be used, turn off voice mode, image creation and memory, and prevent the chats from being used to train the models. You can now also set that new regular chats start in study mode; according to the Help Center, chats in GPTs and projects are excluded. The OpenAI Help names two limits explicitly: you cannot see your child's conversations, and your child can unlink the accounts at any time (you are then notified). According to OpenAI, only accounts of users aged 13 and older can be linked.

Teen mode. "ChatGPT for Teens" has existed since August 18, 2026. If a teenager asks for a quick answer, ChatGPT can, according to OpenAI, guide them to the steps they can use to solve the task themselves. In addition there are homework reminders and study hours in which new regular chats start in study mode (again without GPTs and projects). In the section on parental controls, OpenAI itself writes that such guardrails are not airtight and can be bypassed if someone deliberately tries.

What study mode can and cannot do

OpenAI introduced study mode on July 29, 2025, and it is also available on the free plan. Instead of giving the solution right away, ChatGPT asks follow-up questions, gives hints and goes through a task in steps. According to the Help Center, you can also upload a worksheet or a photo of a math problem.

What it can do:

  • ask questions instead of giving away the answer: What do you already know, where are you stuck, which step would you try next?
  • explain a method in small steps and check with questions whether it was understood
  • work with uploaded material, for example a worksheet

What it cannot do:

  • Reliably stay switched on. You switch it on in the chat and just as easily switch it off again: according to the Help Center, it is enough to remove the "Study" icon in the input field. The setting in parental controls only determines that new regular chats start in study mode, with GPTs and projects excluded. OpenAI does not describe a lock against switching it off.
  • Address elementary school kids. According to OpenAI, study mode was developed with college students in mind. In the Help Center, the examples for your own learning level range from "middle school" to "college".
  • Work without errors. At launch, OpenAI itself admitted inconsistent behavior and mistakes ("inconsistent behavior and mistakes"). The terms of use state in general that outputs are not always correct.

How to use ChatGPT yourself when your child is stuck

You can have ChatGPT explain a task to you and pass it on to your child in your own words. Three templates to adapt:

  1. "My child is in grade 3 and is practicing written subtraction. This is how the class does it in the notebook: (insert example from the notebook). Explain this method to me so that I can explain it to a nine-year-old. Do not give the result."
  2. "Here is a word problem from grade 2: (insert task). Which questions can I ask my child so that they figure out for themselves what is being asked?"
  3. "Give me a similar task with different numbers so that we can practice the method together."

Include the calculation method from class and compare the explanation with the notebook before you pass it on. If the class practices a different method, the one from class applies.

AI for school at home: numbers from Germany

According to the KIM study 2024 (in German), 81% of the surveyed schoolchildren between 6 and 13 never use AI for school at home, and only 7% do so at least once a week.

Many parents are skeptical. In a Forsa survey commissioned by the education publisher Raabe (in German), 73% of the surveyed parents feared that AI tools make cheating on exams and homework easier. Even so, 58% rejected a general ban on AI in class (Berliner Zeitung, July 2023).

You have time until your child is 13. Instead of a ban, which comes up for debate again at the latest with the first phone of their own, you can introduce your child step by step: first understand what AI is, then try it out together, and at 13 an account of their own with rules.

Cheating or learning: the difference that matters

"Using ChatGPT" is really two different things.

Example: two ways to ask

Option A: ChatGPT solves the task. The question is "What is 347 minus 189?", and 158 goes into the notebook.

Option B: ChatGPT explains the method. The question is "Explain to me how to subtract 189 from 347 without telling me the result." A good answer shows, for example, counting up: from 189 to 200, then on to 347. In the end, the child does the calculating.

From the outside, both options look the same: the notebook is done. The difference lies with the child: with A, they copied a number, with B they practiced a calculation method.

A parent of a 14-year-old describes on Reddit how easily "help" turns into option A: "every time I let him use ChatGPT for "help," he just prompts it to write the whole thing."

The default decides

In the normal chat, ChatGPT gives the solution directly on request. Study mode has to be switched on, and the homework reminder only exists in the teen version. For option B to happen, a child has to know how to ask and also want to. That is a lot to ask of an elementary school child.

What the research says

1. Unrestricted access can harm learning. In a field experiment with almost 1,000 students in grades 9 to 11 in Turkey (Bastani and colleagues, PNAS 2025), GPT-4 improved results during practice. When access was taken away afterward, the group with the regular chatbot did 17% worse than teenagers who never had AI access.

2. Guardrails largely weakened the disadvantage in this experiment, but there was no advantage. A second group used a version with built-in guardrails (GPT Tutor). According to the study, the negative effect was largely weakened for them. According to the OECD Digital Education Outlook 2026, this group did about as well on the test without aids as teenagers who had studied on their own.

3. Habit formation is an issue. In a US survey by Common Sense Media of 1,204 children and teenagers aged 9 to 17 (March 2026), 16% of those who use AI for homework said they find it hard to get started or finish without AI. Among daily users it was 28%.

4. Education policy is cautious. The Standing Scientific Commission (SWK) of the Kultusministerkonferenz (the conference of the German state education ministers) recommends largely doing without AI language models in elementary school. In their recommendation for action on AI from October 2024 (in German), however, the states consider this abstention "in need of discussion".

The experiment ran with teenagers, the survey with 9- to 17-year-olds in the US. The results can only be applied cautiously to elementary school kids in Germany. For homework it still means: homework is practice. If an AI takes over the practice, the task is done, but nobody has practiced.

What elementary school kids can use instead

"ChatGPT is not for elementary school kids" does not help on its own when your child is sitting in front of the task. Three ways that suit the age:

  1. You explain, ChatGPT helps you. With the templates above, you have the method explained to you and pass it on in your own words.
  2. An app built for kids. Make sure it explains the method instead of delivering results, that it checks your child's answer and reads tasks aloud as long as your child does not read fluently yet. You will find more criteria in our checklist on which AI is suitable for kids.
  3. People. The teacher, staff providing homework support (Hausaufgabenbetreuung), or an older sibling who explains instead of telling the answer.

Gennady is our own product, an app for iPhone and iPad, built for the second way: your child photographs the worksheet, Gennady reads the task aloud, word for word so they can read along, explains the method step by step and checks your child's answer. If the answer is wrong, there are hints first; Gennady shows the correct solution for comparison only on the third try. The last hint leads right up to the result; your child takes the last step on their own. This applies to tasks from the worksheet: if your child types in a question freely or chats without a task, Gennady answers directly. For the differences from ChatGPT in detail, see our comparison of Gennady and ChatGPT.

An app replaces neither the teacher nor you. If the basics are missing, for example if the multiplication tables are still not in place in grade 4, your child needs practice and guidance from people. Talk to the teacher then.

Family rules by age

A suggestion for how you can use AI depending on age:

AgeChatGPT and AIYour role
Grades 1 and 2no ChatGPT; at most an app built for kids, and then togetherread aloud or have it read aloud, listen, ask follow-up questions
Grades 3 and 4no ChatGPT account of their own; apps that explain and check the child's answeruse ChatGPT only yourself, to explain; ask in the evening what was hard
from age 13own account only with your permission; link accounts, study mode as the default or study hours, quiet hourstalk regularly, because you cannot see the chats

Rule 1, at every age

The child writes the answer. AI may explain, read aloud, show an example or talk through a similar task. What goes into the notebook comes from your child's head.

Rule 2: Questions instead of answers. Practice with your child how to ask: "How can I remember what 7 times 8 is?" instead of "What is 7 times 8?" That is a skill your child will also need later, when they ask on their own at 13.

Rule 3: One question after homework. "What was hard today, and how did you manage it?" If the answer is regularly "I looked it up", a conversation is worth it. If it is "I thought about it, got a hint and then understood it", things are going well.

Rule 4: Ask the teacher. Whether and how AI is allowed for homework is up to the school. OpenAI, too, advises in the Help Center to follow the school's AI rules for graded assignments.

If your child secretly uses ChatGPT

The first reflex is understandable: take the device away, lay down the law. Try this instead:

  1. Breathe first. Bring it up calmly the next day, not in the heat of anger.
  2. Ask instead of accusing. "Show me how you did that" opens more than "You cheated!"
  3. Listen to what is behind it. Maybe your child did not understand the task, did not dare to ask, or was under time pressure. If word problems are the sticking point, the steps in Child Doesn't Understand Word Problems help.
  4. Explain the difference. With options A and B from above: copying is something different from having the method explained.
  5. Agree on a rule together. For example: "If you get stuck, you come to me. We only use ChatGPT together, and I do the asking."
  6. Stay in conversation. Try a calm conversation first instead of a punishment, and ask in the coming weeks how the rule is working.

Frequently asked questions

Is it OK to use ChatGPT for homework?

OpenAI allows use from age 13 and with a parent's permission, not under 13. Whether AI is allowed for a particular homework task is up to the teacher. For elementary school kids that means: no account of their own. As a parent, you can have ChatGPT explain a task to you and then explain it to your child yourself.

Is it cheating if my child uses ChatGPT for homework?

It depends on how. Having a method explained and then doing the calculation yourself is learning. Taking over a finished solution without understanding it is copying. The test: can your child explain the method in their own words and solve a similar task on their own?

Can ChatGPT solve math problems?

Yes, ChatGPT works out problems step by step, including from an uploaded photo. But the results can be wrong: OpenAI states in its own terms of use that outputs are not always correct. For elementary school tasks, include the calculation method from class and compare the explanation with the notebook.

Is ChatGPT safe for kids?

According to the terms of use, ChatGPT is not intended for children under 13. For 13- to 17-year-olds there has been a teen version with stronger safety filters since August 2026, plus parental controls. OpenAI itself writes that such guardrails can be bypassed if someone deliberately tries. They do not replace regular conversation with your child.

Can I see what my child talks about with ChatGPT?

No. Even with linked parental controls, according to OpenAI you get no access to your child's conversations or history. You can manage settings and are notified in rare, serious cases, such as signs of self-harm. You only learn more if your child shows you what they asked.

How can I tell if my child is just copying with AI?

Possible signs: the homework is done strikingly fast or does not sound like your child, and when you ask, they cannot explain the method. The simplest test: have your child solve a similar task in front of you or explain the method in their own words. Respond with a conversation instead of punishment.

Hints first, then the solution

Gennady reads the task aloud, explains the method step by step and checks your child's answer. If the answer is wrong, there are hints first; the correct solution for comparison only on the third try. Try it free for 7 days.
