Data protection in practice
Practical steps for Irish teachers — what to strip from documents before uploading, what never to type into a prompt, and how to use AI safely within your GDPR obligations.
Why this is easier to get wrong than you think
Here is the thing about GDPR and AI tools: the risk is not that teachers are careless. It is that using an AI tool feels like thinking out loud. You are sitting at your desk, you type a prompt, you get a response. It does not feel like data processing. But legally, it is.
When you type something into a free AI tool, that text is sent to and processed on external servers. The data handling terms vary widely. Some tools use conversation content to improve their models. Some store it. Most teachers do not know exactly what happens to what they type — and that uncertainty, when it involves personal data, is a compliance issue.
So what counts as personal data? Under GDPR, it is any information that identifies or could identify a living person. In a school context, that is a long list.
| Type of data | Examples | Safe to use in AI? |
|---|---|---|
| Student name | Full name, first name if identifiable | No |
| Contact details | Address, phone, email of student or parent | No |
| Assessment results (named) | "Aoife got 72% in her Christmas test" | No |
| SEN and medical information | Learning profiles, diagnoses, medication needs | No |
| Safeguarding information | Any pastoral or child protection detail | Never |
| Parent and guardian details | Names, contact info, family circumstances | No |
| Anonymous class information | "A class of 28 3rd Year students, mixed ability" | Yes |
| Generic scenarios | "A student who struggles with fractions" | Yes |
| Your own curriculum materials | Lesson plans, slides, worksheets (no names) | Check first |
| School name with identifiable detail | "At St. Brendan's, in Ms Kelly's class…" | Caution |
How to anonymise a document before uploading it
The good news is that anonymising a document before uploading it is a five-minute job, not a major undertaking. Work through these steps in order before you open any school document in an AI tool.
- Use Find and Replace. In Word or Google Docs, press Ctrl+H (or Cmd+H on a Mac). Find each student name and replace it with "Student A", "Student B" and so on. Do this before you open the document anywhere else.
- Remove headers and footers. School documents often carry the school name, class, and teacher name in headers or footers. Delete them or replace with generic text before uploading.
- Check comments and tracked changes. These frequently contain names. Accept or delete all tracked changes and remove all comments before uploading.
- Remove document metadata. Word documents store the author name and edit history in hidden metadata. In Word: File → Info → Check for Issues → Inspect Document → Remove Personal Information.
- Read it once more. Scan the full document before uploading. Names and identifying details appear in unexpected places — examples, feedback notes, annotations.
Safe prompting — what to change and why
You do not need to give the AI the full context to get a useful response. Here is what that looks like in practice — the same task, prompted safely and unsafely.
✗ Unsafe — do not type this
✓ Safe — use this instead
✗ Unsafe — do not type this
✓ Safe — use this instead
So what does that mean for how you work? You add the name, the subject, the specific individual detail — yourself, afterwards, in your own system. The AI does the drafting. You do the personalising. That is the workflow, and it keeps you safe.

Tick each item before you start. Your ticks are not saved — this is a personal reminder only.
