The trial is the one hour that decides the next year of your child's schedule. Most families waste it watching the teaching. Here is what to watch instead.

Parents recommend trial lessons to each other constantly, and then most of us use them badly.
The usual approach is to watch whether the teaching looks good, the materials look thorough, and the centre looks organised. All of that is real, and none of it is the thing that determines whether your child improves.
What determines that is fit with one specific person. Families leave centres when a good teacher leaves, which tells you the teacher was the product all along.
If you can observe, resist grading the teaching. Watch these four things instead.
| Watch for | A good sign | A warning sign |
|---|---|---|
| When your child is wrong | The teacher asks what they were thinking, then corrects the thinking | The teacher gives the right answer and moves on |
| Who is doing the work | Your child is talking, writing and attempting | The teacher is explaining beautifully while your child watches |
| Diagnosis | The teacher spots the actual weakness within the hour and names it | The lesson is generic and could have been taught to anyone |
| Your child's face | Leaning in, asking one question, willing to be wrong | Polite, quiet, waiting for it to end |
Three questions, and the quality of the answers tells you most of what you need.
Ask it on the way home, before anyone else's opinion lands: did you understand more at the end than at the start?
Not whether they liked the teacher, because likeable and effective are different, and a child who enjoyed a comfortable hour may have learnt nothing. Not whether it was easy, because easy usually means it was pitched below them.
Understanding more is the only outcome that matters, and children answer that question honestly when it is asked plainly.
Do not sign in the corridor. Go home, and give it a week only if you are genuinely unsure, because the answer rarely improves with delay.
If you go ahead, write down the gap you named and the change the teacher predicted, then diary a check for six weeks out. That note is what stops a subscription running for a year on autopilot, which is the failure mode we wrote about in when tuition is not the answer.
And do trial more than one place if you can. A single trial tells you whether that teacher works, while two tell you what fit actually feels like for your child.
Watch your child in the trial, not the teacher. I know that sounds backwards when you are the one paying and the teacher is the one being assessed, but the teacher will be good in a trial almost every time, and that tells you very little.
What tells you everything is the moment your child gets something wrong. A teacher who asks what were you thinking is going to be useful for a year. A teacher who simply supplies the right answer will produce a child with beautiful notes and no independence, and you will not find out until the exam. The correction is where teaching actually happens, and it takes about ninety seconds to observe.
So use the free hour for what it is worth. Name the gap before you go, bring the last paper, and on the way home ask one question: did you understand more at the end than at the start? If your child says yes, you have found something worth paying for. If they hesitate, you have just saved yourself a year, and that is exactly what a trial is for.
No, and centres expect it. Trials exist precisely so both sides can check fit, and a centre confident in its teaching would rather you arrive convinced than sign reluctantly and leave in two months.
Children often agree to avoid disappointing you. Ask for something concrete instead of a verdict: what is one thing you can do now that you could not do this morning? If nothing comes, the hour did not land, whatever they said about liking it.
In the real class, if you are considering group tuition. A solo trial tells you how the teacher performs with undivided attention, which is not the product you would be buying. We compare the formats in one to one versus group.
