There are a very large number of online English teachers, and the differences between them matter more than the price differences suggest.
Here is what actually separates a teacher who moves you forward from one who is simply pleasant to talk to.
Conversation partner or teacher?
This is the distinction most learners do not make, and it costs them months.
A conversation partner gives you speaking time. Valuable — speaking time is what most learners lack.
A teacher does something different: they identify the specific habits capping your level, and design practice against them.
Everyone has three or four such habits. They are usually invisible from inside your own head, and they are rarely the ones you are worried about. Someone who has taught hundreds of learners at your level spots yours quickly.
Both roles are legitimate. But if you are paying for lessons and receiving conversation, you are paying for the wrong thing.
The test: after two or three lessons, can you name one habit they identified and one thing you are working on? If not, you are getting conversation.
Native versus non-native: mostly the wrong question
The debate is popular and largely beside the point.
A trained non-native teacher has learned English as an adult and solved the exact problems you are facing. They can explain why a structure is hard for a speaker of your language, because it was hard for them.
A native speaker has an advantage on natural usage, register and the instinct for what sounds right.
Teaching training is the variable that predicts outcomes. An untrained native speaker and an untrained non-native speaker will both, in practice, chat with you.
What to look for
They ask about your goal before the first lesson. "I need English for job interviews in six weeks" and "I want to read novels" require completely different lessons. A teacher who does not ask is running the same lesson for everyone.
They correct selectively. Correcting everything stops you speaking; correcting nothing wastes the session. Good teachers correct a small number of things per lesson — usually the ones that affect being understood, plus one recurring habit.
You speak most of the time. In a speaking lesson, the student should be talking substantially more than the teacher. It is worth actually noticing this: teacher-dominated lessons feel productive and are not.
They tell you what to do between lessons. Progress happens between sessions. A teacher who does not shape that is only using a fraction of their influence.
Warning signs
- Every lesson is a free conversation with no structure or progression.
- No corrections at all, or corrections only of vocabulary and never of habits.
- They talk more than you do.
- You cannot say what you are currently working on.
- Lessons feel pleasant but you cannot identify what changed in three months.
That last one is the important one. Enjoying lessons is necessary — you will not sustain lessons you dread — but it is not sufficient.
Getting value from lessons you are already paying for
Most learners could get considerably more from their existing lessons without changing teacher.
Arrive with a specific goal. "I have an interview on the 14th, can we do mock questions?" produces a far better lesson than "let's just chat".
Ask for the diagnosis directly. What are the three things most limiting my English right now? Good teachers answer immediately; the answer is often not what you expected.
Do the between-lesson work. The lesson is where errors get identified and pressure gets applied. The fixing happens in your own practice.
Bring real material. The email you have to send, the presentation you have to give. Lessons built on your actual life transfer to your actual life.
How iTellU handles this
Every teacher on iTellU goes through a structured recruitment process before they take a single lesson — assessment of their speaking, their teaching, and a review of how they actually run a session — because "anyone can sign up and teach" is precisely how learners end up paying for conversation.
Lessons are live and one-to-one, and the AI practice in the app covers the between-lesson repetitions, so the time with your teacher goes on the things only a person can do: diagnosis, pressure and correction.
FAQ
- Native speaker or non-native teacher?
- Teaching skill matters far more than nationality. A trained non-native teacher who has learned English themselves often explains difficulties better, because they have solved them personally. Native speakers have an edge on natural usage and register. Both work; an untrained teacher of either kind does not.
- How often should I take lessons?
- Once a week sustains progress; twice a week creates it. What matters more is what happens between lessons — a weekly lesson with daily solo practice beats three weekly lessons with nothing in between.
- How do I know if a teacher is actually good?
- After two or three lessons you should be able to name one specific habit they identified in your English and one thing you are working on. If you cannot, you are having conversations rather than lessons — pleasant, but not the same thing.
- Are online lessons as effective as in person?
- For speaking practice, yes — and often better, because they are easier to schedule frequently, and frequency is what drives progress. The main requirement is a stable connection and a setup where you can talk out loud comfortably.
