How to Hire a Tentor for a Bimbel, and What the Trial Lesson Actually Tells You

What does a CV actually tell you about a tentor?

The candidate with the best transcript is the one whose Tuesday class has quietly gone from nine students to five, and nothing in the folder you read beforehand predicted it. A CV is a coverage document. It tells you which subjects a person can teach and which level they are comfortable at, and you do need both of those.

What it cannot tell you is whether they notice the child at the back who stopped writing four minutes ago, or what they do next. That noticing is most of the job and it is invisible on paper.

So give the CV one job and no more, which is to decide who you spend a Saturday morning watching. Screen for subject and level, screen out anyone who cannot work the slot you are actually trying to fill, then stop reading.

The advert decides who applies

Most of a weak shortlist is made before anybody applies. An advert written about the subject attracts people who like the subject, and an advert written about the room attracts people who can work in it. Name the level, the size of the class, the day, the hour, and whether the work is one long block or sessions scattered across the week.

Be specific about the slot you need covered, because that is where late withdrawals come from. A candidate who is only free on the evenings you have already staffed will get all the way to an offer before either of you notices. Three weeks of process then disappears into a detail that belonged in the first line of the advert.

Ask for one thing in the application that costs a little effort. A few lines on how they would explain one specific topic to a student who has already failed it twice will separate the shortlist from the mass applicants in an afternoon, and it is the one part of an application nobody can lift from a template.

How do you run a trial lesson that is actually a test?

Put the candidate in front of your real students rather than a room of your own staff playing the part. Staff cannot fail to understand something on cue, and the entire point of the exercise is to watch what happens when a child genuinely does not follow. A room of adults being helpful tests nothing.

Give them a topic from the syllabus you are actually running, and give it to them the day before rather than the week before. You are not testing whether somebody can build a showpiece lesson given seven days. You are testing whether they can prepare a normal Thursday under the conditions your tentors work in every week.

Ask for the middle of a topic, never the introduction. An opening lesson is the easiest one anybody teaches, because nobody in the room is behind yet.

Sit at the back, take the register yourself so your hands have something to do, and do not step in. If a candidate loses the room and you rescue them, you have learned nothing except that you can teach. Twenty minutes is enough.

Watch what happens the first time a student says they do not understand. The weak version repeats the same explanation more slowly and slightly louder. The version you want drops that explanation and reaches for a different example, and it does so within a sentence or two.

Watch where they stand and who they are facing. Long stretches of writing on the board with their back to the room is the mark of somebody who has taught adults, or nobody. Watch whether the back row gets a name, a question, or any eye contact at all.

Watch the clock, and let them finish rather than telling them when to stop. Running well over a twenty minute slot is not enthusiasm, it is the reason your Thursday evening runs late every week of term.

The twenty minutes after the lesson

Take the candidate somewhere quiet straight afterwards and ask what they would change. Someone who says nothing either was not watching the room or will not take a correction, and both cost you the same in the end. Someone who names the exact moment it went flat has told you they can see their own class, which is the hardest thing on this list to train.

Then ask what they would do if a parent messaged at nine at night about that lesson. You are not looking for the right answer, because there is not one. You are looking for whether it occurs to them that the message is the centre's problem before it is theirs.

What should you ask a reference?

Ask for the person who built their timetable, not the person who signed them. A coordinator knows who cancelled on a Friday, who arrived after their students, and who had to be chased for a make-up class. A director mostly knows the interview.

One question does most of the work, and it is whether they would put this person in front of their hardest class. A pause before the answer is usually the answer.

After that, ask only about ordinary things that have ordinary answers. Did they turn up before the students, did they say something when they could not come, did any parent ever ask for them by name. Vague warmth about attitude is not a reference and should be read as one.

How do you know in the first term whether you chose right?

You will want to know inside a term rather than at the end of a year, and three things are worth watching. None of them is a test score, and all three sit in records a bimbel already keeps.

The first is whether the sessions actually ran. Your class schedule holds what was meant to happen and your attendance register holds what did, and the gap between the two is the earliest signal you get. Digital attendance with timestamps is entered by staff on a staff device, a parent cannot check their own child in, and none of it records without a connection, so what you are reading is what your staff logged rather than who walked through the door.

The second is whether the students came back. Read it per class and per term rather than across the centre, because a centre-wide retention figure averages a strong tentor and a struggling one into a number that tells you nothing about either. A class that loses two students in its first month is a conversation, not a verdict.

The third is whether parents have started asking for this person by name. It shows up in reschedule requests, in what gets asked at the desk, and in which class a younger sibling is enrolled into. It is the slowest of the three to appear and the one worth weighting most heavily.

Two things the record will not settle

None of this tells you how many adults a room needs. Happy Kamper does not track staff-to-child ratios, so that number stays a judgement you make against your own rules and your regulator's, and the software has no view on it. Do not let a schedule that looks full stand in for the calculation.

And no signal settles whether a slow first term is the tentor or the slot. Move them once, to a different day and a different level, before you decide it is them. A Thursday evening class nobody could ever fill is not evidence about a person.
