Quick answer (55 words): Private and matriculation schools hire mainly on the demonstration lesson. Your qualification gets you into the room; what decides it is whether you can hold a class, explain something clearly to children who do not yet understand it, and answer a question you were not expecting. Everything else is secondary.
This page is written from the school's side of the table, which is the side nobody describes to students.
It covers private and matriculation hiring. Government recruitment works completely differently and is covered separately — there, a competitive examination does most of the deciding.
The demonstration lesson decides it
If you remember one thing, this is it.
Most schools will ask you to teach — a real class or a simulated one, usually twenty to thirty minutes, often on a topic given to you shortly beforehand. The people watching have seen a great many of these and they form a view quickly.
What they are actually watching for:
Can you be heard and understood at the back? Basic, and the most common failure.
Do you check whether anybody has followed you? A candidate who explains for twenty minutes without ever finding out what landed is teaching at the room, not to it.
What happens when a child does not understand? Explaining the same thing louder is the wrong answer. Explaining it a different way is the whole job.
Can you handle an interruption without losing the thread? Something will go wrong. They want to see what you do next, not that nothing went wrong.
Do the children respond to you? Fifteen minutes in a room with a class tells an experienced head more than an hour of interview.
What matters less than students expect
Said plainly, because a lot of anxiety is spent in the wrong places.
Marks. Beyond meeting the eligibility threshold, your percentage is rarely the deciding factor. Nobody in a staffroom knows what anybody else scored.
Which college you attended, unless its approval is in question — in which case it is disqualifying rather than merely unhelpful.
A long list of certificates. A workshop certificate does not tell a head whether you can hold a class. The demonstration lesson does.
Confidence, as a performance. Schools are not looking for polish; they are looking for somebody who can be told something and adjust. Over-rehearsed candidates often do worse than nervous, responsive ones.
What helps more than students expect
The asymmetry runs both ways.
Your teaching-practice record file. Actual lesson plans, observations and reflections are the most concrete evidence you have of what you can do. Bring it. Very few candidates do, and the ones who do stand out immediately — which is one more reason record work is worth doing properly.
A reference from somebody who watched you teach. Worth more than any number of general references. Your supervising teacher is that person.
Knowing something about the school. Its board, its size, its intake. Two minutes of preparation, and it distinguishes you from candidates applying everywhere identically.
Willingness to take the classes that exist. Schools have gaps in specific subjects and specific years. Flexibility about which is a genuine advantage.
Honesty about what you have not done. Heads hire people who will ask for help in their first term. A candidate who claims to find nothing difficult is a risk, and an experienced interviewer knows it.
How to read a placement claim — including ours
We are going to apply this to ourselves, because a page telling you to be sceptical while exempting itself is worth nothing.
Four questions for any placement percentage you see, from any college.
Of what? The percentage of what denominator — everybody admitted, everybody who graduated, everybody who registered for placement, or everybody who wanted a teaching post? These give very different numbers from the same cohort.
For which year? A claim with no year attached cannot be checked and cannot go stale, which is precisely why undated claims are common.
Placed as what? Teaching posts, in schools, in the subject trained for — or any employment at all?
Measured when? On the day of graduation, six months later, a year later? The number moves a great deal.
Now ours. This college publishes a placement claim in its own records, and it carries no year. By the test above, that makes it a claim you cannot verify — so we are not going to repeat it here as though it were evidence, and we have asked internally for the year to be added. If a figure matters to your decision, ask the department for the cohort, the denominator and the date, and treat any college that will not give you all three — including us, if we do not — as not having answered.
What the school is actually deciding
Useful to understand, because it explains why the process is shaped the way it is.
A school appointing a teacher is committing an entire class of children to that person for a year. Nobody can undo it in November. That single fact drives everything else.
They are hiring for reliability more than brilliance. A teacher who is competent every Tuesday matters more than one who is exceptional twice a term. This is why the demonstration lesson rewards steadiness over flourish.
They are assessing risk, not ranking candidates. The question in the room is closer to "can this person be left with 9B in March" than "who is the best of these five".
They are hiring somebody they will work beside. Staffrooms are small. How you treat the office staff on the way in is noticed, and it is noticed by people who will be asked afterwards.
They are looking for somebody who will still be there next year. A candidate who is visibly using the post as a stopgap while waiting for something else is a cost, and heads have learned to spot it.
None of this argues for pretending. It argues for showing the parts of yourself that are actually relevant — which most candidates, understandably nervous, forget to do.
Preparing properly
Five things, in the fortnight before you start applying.
Practise a twenty-minute lesson on a topic you did not choose. With somebody watching, out loud. This is the actual test and almost nobody rehearses it.
Assemble your file. Lesson plans, observations, reflections, certificates, the reference from whoever watched you teach.
Prepare for the two questions everyone is asked: why teaching, and what you would do about a child who is disengaged. Have an answer built from something that actually happened to you.
Have a question of your own. About the classes, the year groups, how new teachers are supported. It signals that you are choosing too.
Apply before the academic year is arranged. Private school hiring runs on the school's calendar, and the strongest positions are filled early.
Your first year of teaching covers what happens after all this, which is the part nobody prepares for at all.
If it does not go your way
It happens to most people at least once, and how you take it matters more than the rejection does.
Ask what you could have done better. Many heads will tell you, briefly and usefully, if you ask without arguing. It is the single most valuable feedback available to you and it costs one polite question.
Do not read one rejection as a verdict on your teaching. Schools appoint for a specific gap — a subject, a year group, a timetable. A strong candidate for the wrong vacancy is still the wrong candidate, and that is not about your ability.
Apply again next year if it was a school you wanted. Being remembered as somebody who improved is a real advantage, and heads do remember.
Keep teaching in the meantime, in any setting you can. Substitution, tuition, part-time work. Time in front of children is the thing that improves the demonstration lesson, and nothing else substitutes for it.
Where we sit
JKKN College of Education is an NCTE-approved, NAAC-accredited B.Ed college in Namakkal district, Tamil Nadu 638183, founded in 2016 under the J.K.K. Rangammal Charitable Trust.
Approvals, NAAC grade and founding year from the JKKN facts master sheet, 30 July 2026. Name, trust and contact details read live from edu.jkkn.ac.in on 1 August 2026. No placement percentage is quoted on this page, by design. The affiliating university is not currently published on this site and is therefore not stated here.
If you are our student, the most useful preparation available to you is free: ask a member of staff to watch you teach a full lesson and tell you honestly what they saw. Contact the department or the college office and ask for it. Almost nobody does.
Frequently asked questions
What do schools look for when hiring a teacher?
Mainly the demonstration lesson — whether you can be understood, whether you check that children have followed you, what you do when somebody has not, and how you handle something going wrong. The qualification gets you into the room; the lesson decides it.
Do my marks matter when applying to schools?
Beyond meeting the eligibility threshold, rarely. What matters far more is evidence that you can hold a class, which comes from the demonstration lesson and from your teaching-practice record.
What should I bring to a teacher interview?
Your teaching-practice record file with real lesson plans, observations and reflections; a reference from somebody who actually watched you teach; and your certificates. The record file is the item most candidates leave at home and it is the most useful one.
How is private school hiring different from government recruitment?
Private and matriculation schools hire directly, usually before the academic year, and decide largely on an interview and a demonstration lesson. Government recruitment is a competitive examination run by a recruiting authority on its own schedule, with posting decided by allotment rules.
How should I read a college's placement percentage?
Ask four questions: of what denominator, for which year, placed as what, and measured how long after graduation. A claim missing any of the four cannot be verified, and undated claims in particular should carry no weight in your decision.
Does JKKN College of Education quote a placement percentage on this page?
No, deliberately. The college's own recorded placement claim carries no year, which by the test set out on this page makes it unverifiable. Ask the department for the cohort, the denominator and the date if the figure matters to your decision.
