Most teachers do not need convincing that time is short. The question is where AI actually gives time back, and where it quietly takes it. A draft that needs an hour of fixing is not a saving.
Plenty of teachers are already trying it. Gallup's May 2026 analysis noted that earlier research finds six in 10 teachers use AI for their work, including three in 10 who use it at least weekly (Gallup). This guide is for teachers who want to be deliberate about it.
Start by finding your time sinks
Before trying any tool, spend one week noting which tasks eat your time. A rough list is enough:
- Planning and preparing materials
- Marking and feedback
- Emails and communication
- Admin, reports and meetings
- Finding or making resources
Choose the one or two that annoy you most. Those are where a saving would matter.
Ten tasks where AI often saves time
Each of these uses AI to draft something you then check and edit. None replaces your judgement.
1. First drafts of lesson outlines. Give grade, topic, time and structure. Then edit hard. Our lesson plan template shows a structure to ask for.
2. Practice questions with an answer key. Ask for a set with rising difficulty, then solve a few yourself. See our worksheet guide.
3. Versions of a text at different levels. See adjusting reading level with AI.
4. Exit ticket and quiz questions. Ask for questions that target a specific misconception. See our list of 40 exit ticket questions and the quality checklist for AI quiz makers.
5. Rubric drafts. A first draft of criteria and levels, which you then trim. See how to write a rubric.
6. Comment banks. A set of reusable feedback phrases for common issues in student writing, such as "Your claim is clear, but the evidence does not support it yet." You write the specific comments; the bank gives you starting points.
7. Parent and family emails. A first draft of a routine message. Read it aloud and edit it into your own voice. Never include a student's name or details in a general tool.
8. Vocabulary lists and glossaries. Key terms with student-friendly definitions for a unit.
9. Sub plans and routine documents. A clear, structured plan for a cover teacher, which you fill in with class specifics.
10. Brainstorming. Ideas for hooks, real-world examples, project topics or ways to explain something differently. The value is in the volume. You choose.
Three tasks to be careful with
Grading student work on your own
Gallup found that among teachers who received guidance on using AI to grade student work, 10% said they were discouraged from doing so, the highest discouragement rate of any task it measured, though most received neither encouragement nor discouragement. Marking involves fairness, judgement and student information. If you use AI for marking support, keep the final judgement yours, and never paste identifying information.
Anything containing student information
Names, grades, behaviour notes, health information and learning support details do not belong in a general AI tool. See our student data privacy checklist. Describe the situation without identifying it, or do not use AI for that task.
Documents that shape a student's support
Plans for students with additional needs and records of serious incidents are for you, your colleagues and the student's team. They involve sensitive data and professional responsibility.
A prompt structure that saves editing time
Most disappointing drafts come from missing context. Give five things:
Grade and subject: ...
Goal: ...
Time available: ...
Students: (for example, a mixed-level class with several multilingual learners)
Format: (for example, one page, numbered, with answer key)
Then ask for a draft, and follow up with edits such as "shorter" or "more concrete examples." Save your best prompts in a document so you can reuse them next term.
The two-week test
Do not rely on a feeling that AI saves time. Measure it.
- Pick two tasks from the list above.
- Time yourself doing each the usual way for a week (a rough note is fine).
- Use AI for the next week, including the time to check and fix.
- Compare. Count the total time, not just the generating.
- Compare quality too. Was the result as good, better or worse?
- Keep what saves time without lowering quality, and drop the rest.
A common result is that AI saves time on first drafts and brainstorming, and saves little or nothing on tasks where the checking is as long as the doing.
Know the rules before you start
Check your school's rules on AI. Gallup found that only 18% of teachers had received any formal guidance from administrators on using AI, so you may need to ask (Gallup). Ask which tools are approved and what information may be entered. If there is no policy, choose the more careful option. Our guide to free AI tools for teachers includes a six-question check before you adopt a tool.
Summary
- Find your time sinks first, then match AI to those.
- Use it for drafts, questions, versions and brainstorming, then edit.
- Be careful with grading, student information and support documents.
- Test for two weeks and count the checking time.
