Most formal complaints arrive because something earlier was handled badly. A phone call not returned, a meeting where a parent felt talked over, or a decision explained after it was made rather than before.

By the time it’s in writing, the complaint in front of you is frequently not the thing the parent is actually upset about. Investigating well means finding both, answering the first properly and acknowledging the second.

It’s understandable that leaders find these draining. Many headteachers tell us the complaint itself was manageable and what wore them down was the sense that nothing they wrote would settle it. That’s usually a sign the underlying issue hasn’t been named.

In this guide we’ll set out how to run a formal complaint investigation that’s fair, defensible and, ideally, ends the matter. The wider framework it sits inside is covered in our guide to school investigations.

What Does Your Complaints Procedure Require?

Read it before you do anything else. Not the version you think you have, the one published on your website.

Check the number of stages, the timescales for each, who handles each stage, and what your panel arrangements are. Then check you can actually comply. Schools frequently discover at this point that their published timescale is ten school days and the person named for stage two is on leave for three weeks.

If you can’t meet a timescale, write to the parent, explain why and give a new date. That’s a reasonable position. Silence isn’t, and it hands the parent a second complaint about how the first was handled.

Different school types work to different frameworks. Independent schools must meet the complaints requirements in the Independent School Standards. Maintained schools operate under section 29 of the Education Act 2002 and follow their own published procedure. Academies must have a procedure required by their funding agreement, with escalation available beyond the trust.

How Do You Define the Scope of a Complaint Investigation?

This is the step most often skipped and the one that causes the most difficulty later.

Write down, in numbered points, exactly what you’re investigating. Send it to the complainant and ask them to confirm it’s right.

That does three things. It stops the investigation expanding indefinitely, it gives you something to write your findings against, and it frequently produces a reply that clarifies what the parent actually wants.

Where a complaint contains many points, group them. Six allegations about communication are usually one issue. Be careful not to lose a serious point inside a group.

Some things don’t belong in a complaints procedure at all. Safeguarding concerns go into the safeguarding process. Allegations against a member of staff meeting the harm threshold go to the local authority designated officer. Matters relating to admissions, exclusions or SEND provision usually have their own statutory route. Say clearly which route applies and why, rather than declining to look at something without explanation.

Good practice

  • Read your published procedure before you start, and check you can meet its timescales
  • Write the scope in numbered points and send it to the complainant to confirm
  • Route safeguarding, exclusions and SEND matters to the correct process and say so
  • Answer each numbered point separately in the outcome letter
  • Say what you are doing differently, because that is what most parents want

What Evidence Should You Gather When Investigating a Complaint?

Start with the documents, because they’re contemporaneous and nobody’s memory is.

Emails, letters, meeting notes, behaviour or incident logs, attendance records, and the child’s file where it’s relevant. Build a dated chronology as you go. That chronology usually does more work than anything else in the investigation, and it frequently reveals the actual problem.

Where a document doesn’t exist that should, record that. “There is no record of the meeting on 14 March” is a finding in itself, and it’s often the finding.

Be careful with data protection. You’re processing personal data about a child, about staff and sometimes about other families. Only look at what’s relevant to the scope, and remember that anything you write may be disclosed later in a subject access request.

Who Should You Interview During a Complaint Investigation?

The people who can answer the numbered questions, and no more than that.

Speak to the complainant first if you can. It’s frequently the most useful hour of the investigation, and parents who feel heard at that stage will accept a finding they don’t like far more readily.

Interview staff properly rather than in a corridor. Give notice, say what it’s about, and record what was said. We cover this in how to conduct investigation interviews in schools.

Think carefully before speaking to a child. Where the complaint concerns a pupil’s experience it may be necessary, and it needs planning with your safeguarding lead rather than being arranged casually. In a special school or alternative provision, communication needs have to shape the approach entirely.

How Do You Reach Findings on a Parent Complaint?

Take each numbered point separately and reach one of three positions: upheld, partly upheld, or not upheld.

Apply the balance of probabilities. Is it more likely than not that this happened? That’s the standard for an internal process, and it’s a lower bar than people assume.

Set out the evidence, then the finding, then the reasoning that connects them. The reasoning is what’s usually missing, and it’s what allows a parent, a panel or a regulator to test your conclusion rather than simply accept or reject it.

Be willing to uphold. A school that has never upheld a complaint isn’t a school with no problems, and parents can tell.

How Do You Write to a Parent With the Outcome?

Plainly, point by point, and in language a worried parent can read in one go.

Address each numbered point with the finding and a short explanation. Say what you’re doing as a result, because that’s what most parents actually want. An apology where one is warranted costs nothing and resolves a great deal.

Set out the next stage of the procedure and how to access it, including the timescale. A parent who has to go looking for that will assume you hoped they wouldn’t find it.

Avoid two things. Defensive language, which parents read instantly and which turns a complaint about an incident into a complaint about the school’s attitude. And legalistic phrasing, which signals that you’ve moved into dispute mode.

Where a complaint proceeds to the panel stage, our guide to school complaints panels and the independent panel member covers what follows.

When Should a Parent Complaint Be Investigated Independently?

Where nobody internal can look at it and be believed.

That usually means the complaint concerns the headteacher or the proprietor, the person who’d normally investigate has already expressed a view, the parent has said in terms that they don’t trust the school to be fair, or the complaint is about culture rather than an individual event.

Capacity counts too. A rushed internal investigation is worse than an independent one, and sometimes the honest answer is that nobody has the time to do this properly.

Where there’s no headteacher in post, the practical arrangements need thinking through separately. We cover that in handling parent complaints when you have no headteacher.

From Our Experience

The complaints that escalate are almost never the ones with the strongest substance. They’re the ones where the parent felt dismissed.

We often see a school investigate carefully, reach a defensible finding, and write an outcome letter that answers the points and never acknowledges the experience behind them. The parent escalates, not because the finding was wrong, but because nobody said “I can see why that was upsetting.”

Many leaders tell us the single most useful thing they did was phone the parent before investigating. Ten minutes of listening frequently reduces a nine point complaint to two real issues, and the parent has already been heard by the time the finding arrives.

The other pattern is scope. Investigations that never defined what they were looking at run for months, expand as new points arrive, and finish with a document nobody can act on.

A Common Misconception

“If we uphold it, we are admitting fault and inviting a claim.”

It’s an understandable worry and, in our experience, the reverse is usually true.

Parents who receive an honest finding, an apology where it’s warranted and a clear account of what’s changing rarely escalate. Parents who receive a defensive letter that upholds nothing frequently do, and by then they’re complaining about the school’s integrity rather than about the original matter.

There’s a more important point underneath it. A complaints procedure is one of the main ways a school finds out what a child is actually experiencing. Treating it as a threat to be managed shuts down the information you most need, and the pupil at the centre of it is the one who loses.

Questions for Leaders and Governors

  • Have we read our published procedure, and can we meet its timescales?
  • Have we written the scope in numbered points and confirmed it with the complainant?
  • Does anything in this complaint belong in the safeguarding process instead?
  • Does our outcome letter give the reasoning, or just the finding?
  • When did we last uphold a complaint, and what does the answer tell us?

Our Perspective

A complaint is uncomfortable to receive and it’s genuinely useful information about your school.

Investigate it properly. Define the scope, gather the documents, listen to the parent early, reach findings point by point with the reasoning shown, and be willing to uphold. Say what you’re changing.

Schools that handle complaints well aren’t the ones that receive fewest. They’re the ones where families believe raising something will lead somewhere, and that belief is worth protecting, because it’s how you hear about the things affecting a child before they become serious.
