Maths tutor, private tutor or homework help: how to choose in the canton of Vaud

A parent looking for help for their child rarely types the same thing twice into Google: maths tutor, private teacher, homework help, academic support. Behind these words the need is identical: someone competent, who understands where the student is stuck, rebuilds what is missing and is accountable. And behind these words lies the real difficulty: nothing in an online listing tells you about the person's actual ability to teach.

Let us say it upfront: there are excellent independent teachers, just as there are excellent teachers in centres. This article does not set out to tell you who is good and who is not, which would be dishonest. It sets out to give you the criteria that genuinely make the difference, so that you can choose knowingly. The real question is not 'who is best?', it is 'what level of selection, follow-up and continuity do you want around your child's teacher?'.

The rest of this article explains why these six points matter, what the different options available in the canton are worth, and how we answer them at SOS. You can use it to assess us just as much as anyone else.

01Becoming an online tutor takes ten minutes

Open any matching platform: creating a tutor profile requires a photo, a few sentences of introduction and a price. Some platforms verify identity or the diplomas claimed, and that is useful. But verifying a profile or a diploma says nothing about how the person teaches in front of a student, and nobody will observe what happens during the lessons. The platforms themselves are open about it: they are directories that connect people, not schools that supervise.

The consequence lands on you. You have to assess, in someone you do not know, the hardest skill there is to judge: not knowing maths, but making maths understood. Without a test or a common benchmark, the measuring instrument left to you arrives months later: your child's report card. By the time it arrives, the semester is gone.

02Knowing a subject and knowing how to teach it: two different professions

This is the most expensive misunderstanding in tutoring. Having passed maths, even brilliantly, does not qualify anyone to teach it. Teaching is something else: diagnosing where understanding stopped, sometimes years earlier; re-explaining a notion differently from the class, then differently again if the second explanation does not land; choosing the right exercise at the right moment; keeping a discouraged student at work who has decided they are 'bad at maths'.

A student who is excellent in their field can be a remarkable teacher. They can also be a mediocre one, who explains the way they themselves understood and grows impatient when that is not enough. Without a teaching test, nobody can know in advance. Not even them.

“A student does not progress because their teacher knows. They progress because their teacher knows how to transmit.”

03The six questions that separate the offers

Whether you choose SOS or anyone else, ask these six questions. A serious counterpart answers them precisely and without taking offence. Evasive answers are, in themselves, an answer.

• Has the teacher passed a teaching test, not just an interview? A diploma shows they know the subject. A teaching test assesses, before a student is entrusted to them, how they explain it.
• Who looks at the teacher's work over time? A teacher working alone can be excellent and self-critical; you simply depend on their own self-assessment. Ask whether a second pair of eyes exists, and how often it is applied.
• What do you receive after each session? If the answer is 'nothing', you will discover in October what you could have known in September.
• How is the origin of the difficulties diagnosed? 'We will go over what is seen in class' treats the symptoms. A real diagnosis goes back to the source, often older than the current school year.
• Is the price displayed, complete, comparable? Beware of teaser rates that state neither the level, nor the duration, nor extra fees.
• What happens if it does not click? The right answer is a simple, quick replacement. The wrong one: a commitment that locks you in with the wrong person.

04The three main options in the canton of Vaud

Matching platforms first. Their strengths are real: hundreds of profiles, quick comparison, often low rates, and someone found within days. They are a good tool when the need is one-off, revising a chapter before a test, for example. Their limit is not a manufacturing defect, it is their model: the platform connects, it does not supervise. Selection, tracking of progress and the reaction when things do not work remain your responsibility.

Word of mouth next: the student from the neighbourhood, the acquaintance with a science degree. Sometimes excellent, often cheap, and the direct relationship has real virtues: continuity, flexibility, trust already established. It is a very good choice when you personally know the person and know that they can teach. The limit is dependence: everything rests on them alone, and if it does not click, nothing will have flagged it before the marks do.

Centres with a teaching team, finally. Their value fits in one sentence: quality there depends less on a single person. The teacher is tested before meeting their first student, their work is reviewed by supervisors, sessions are documented, and they can be replaced if the profile does not fit. It is the most relevant option when difficulties persist, span several topics or require months of follow-up. It costs more than hiring a student directly, and that is logical: you are not paying only for the hour of teaching, you are paying for the selection, the follow-up and the continuity that surround it.

05How SOS selects and supervises its teachers

Rather than asking you to believe us, here is precisely what we impose on ourselves, point by point. Compare it with any other offer: that is exactly the exercise we recommend.

• A teaching test before the first lesson. Our candidate teachers sit demanding assessments before teaching with us: mastering the subject is not enough, they must demonstrate in front of an assessor that they can explain it.
• Assignment decided from the assessment. We do not send 'an available teacher': starting from the initial assessment, we look for the teacher best suited to the subject, the level, the difficulties identified and the student's profile.
• Teaching supervisors who review the teachers' work. Our teachers do not work alone in their corner: their sessions, their reports and their students' progression are regularly reviewed by teaching supervisors.
• A written report to parents after every session. You know what was worked on, what is improving and what remains fragile. It is also an instrument of control: a teacher who documents every session is a teacher who exposes themselves to your scrutiny, and to ours.
• Continuous evaluation. Our teachers are evaluated over time, through the reports, the students' measurable progress and the families' feedback. Teaching well at SOS is not an acquired status, it is a permanent requirement.
• A simple replacement if the profile does not fit. No chemistry? We change teacher, simply and quickly. Your commitment is to your child's progress, not to one person.

06Trust is not declared: it is verified

Anyone can write 'qualified teachers' on a website. Here are three concrete ways to verify us before paying anything. The free educational assessment first: you meet our team, you see our diagnostic method, and you leave with a recommendation, whether you continue with us or not. Google reviews next: they are public, verified, left on our centres' listings by real families, and we never publish an invented testimonial. Fees finally: they are fully displayed on our site, identical for every family, with no mystery quotes.

And once lessons have started, the checking continues: the report after every session lets you see, week after week, whether the support really matches what you were told.

07The special case of maths

Maths stacks up, and the chain is easy to picture: division, then fractions, then algebraic manipulation, then equations, then functions. Each link assumes the previous one. That is why an apparent difficulty with functions in Year 9 can originate several years earlier, in fractions or algebraic manipulation, without anything flagging it at the time. Redoing the week's exercises calms the symptoms; finding the link where the chain broke, and rebuilding from there, treats the cause.

This is the criterion that best separates maths offers: ask how the person intends to identify the origin of the difficulty. If the answer is 'we will go over what is seen in class', you have a répétiteur in the strict sense. If the answer starts with a diagnosis of the real level, you have genuine support.

08Homework help, private lessons, supervised study: which formula for which need?

One last point of method: the right teacher in the wrong formula delivers far fewer results. If the difficulty is focused on one subject, a one-to-one or semi-private lesson with a private teacher is the most direct answer. If the need is broader, homework done and understood every week, a regular working frame, several subjects to hold at once, then it is the structured homework help of our supervised study you should look at: homework is done, checked and understood at every session, tests are anticipated, marks followed all year, with the same report to parents. And if the need is genuinely one-off, a few hours before a test may be enough: we say so when that is the case. The initial assessment exists precisely to point to the right formula, not the most expensive one.

09How it works at SOS, concretely

Everything starts with a free, no-obligation educational assessment, which establishes your child's real level and the origin of their difficulties. We then assign the teacher suited to their profile, one-to-one or semi-private, at our centres in Vevey, Lausanne and Montreux, at home across the Riviera and the Lausanne region, or online. After every session, you receive your written report.

Rates are fully displayed: CHF 70.- per hour for one-to-one lessons at the single-session rate (80.- at secondary II level), 50.- per hour per student in semi-private, and hour packs that bring the price down to 48.40 per hour one-to-one and 30.80 in semi-private. Supervised study starts at 240.- per month. No mystery quotes: everything is on the pricing page.
