What NPS Is and Why Sky Autokool Measures Instructor Trust

Choosing a driving school
Driving instructor
NPS

A score like 4.8 and a sentence like “I’d recommend this instructor to a friend” are not the same thing. The first can mean that nothing went badly. The second means real trust.

A standard rating shows different parts of the job: lesson depth, timing, communication, and how the instructor handles mistakes. We covered those criteria in detail in the article on driving instructor ratings.

After lessons, we ask one more question: How likely are you to recommend this instructor to a friend?

Those answers form our NPS.

What is NPS?

NPS stands for Net Promoter Score. In plain words, this is net promoter score explained: it shows how willing people are to recommend someone.

A rating is about one person’s experience. A recommendation is stronger. If a student is ready to send a friend to the same instructor, they are putting their own name behind that choice. If the lessons go badly, they may have to explain why they made the recommendation. That is why NPS filters out polite scores and shows real trust.

How NPS is calculated

We use a five-point scale and sort the answers into three groups:

  • 5 - Promoters: would recommend the instructor
  • 4 - Passives: no complaints, but no recommendation either
  • 1, 2, 3 - Detractors: would not recommend

The formula is simple: promoters minus detractors. Passives do not count. They do not bring new students in, but they do not push people away either.

Here is a simple example. If an instructor gets 100 ratings, with 85 fives, 8 fours, and 7 scores from 1 to 3, the NPS is 78. That is 85% promoters minus 7% detractors.

The example above is only illustrative. NPS can also be negative if detractors outnumber promoters.

How NPS differs from an average rating

An average score is sensitive to outliers. A single 1 can drag the result down more than a 3, even if both mean the same thing in practice: the student is unhappy and will not recommend the instructor.

NPS handles those scores differently. It puts 1, 2, and 3 in the same group. That means one emotional low score after a bad lesson does not distort the picture as much. You get a steadier answer to the main question: do students trust this instructor?

NPS does not replace the detailed rating. It complements it. Together, the three tools answer three different questions:

  • the criteria breakdown - what is strong and what is weak;
  • NPS - the overall level of trust;
  • the comments - why the score is what it is.

A high NPS and a low timing score is not a contradiction. It usually means students like the teaching but find the schedule hard to manage. You only see that when you look at all three sources together.

Sky Autokool instructors score 78.9

As of the latest collected responses, our instructors’ internal NPS stands at 78.9. Students who would recommend their instructor clearly outnumber detractors.

One important note: we use an adapted five-point scale. Classic NPS uses a 0 to 10 scale, and only 9s and 10s count as promoters. The method is close, but not identical. Because of that, our number is best compared with our own past results, not with scores from companies that use classic NPS.

We would rather explain how we count than publish a nice-looking number with no context.

What this gives you

When you choose an instructor, you already compare the language of instruction, the area, the car, the gearbox, and the available slots. NPS adds one more signal: whether past students would vouch for this person.

That does not mean you should always pick the highest score. People need different things. Some want a calm pace. Others want a stricter push. If you are reading driving school Tallinn reviews, NPS gives you one more way to judge trust. It is a reference point, not a rule.

What it gives us

For an instructor, the score is a clear signal. If it rises, things are moving in the right direction. If it falls, it is time to check the detailed criteria and see what changed.

For the school, NPS is part of our driving school quality measurement. We cannot sit in on every lesson, so NPS helps us see where problems repeat, where quality shifts, and where a teacher may need support or more training.

We do not want to claim that we are the best driving school in Tallinn. We want a way to test that claim. That means measuring quality, collecting feedback often, and making decisions from data, not guesswork.

For students, that means clear information. For instructors, it means feedback. For us, it helps us spot problems early and keep quality steady as the school grows.

Look at the scores yourself

Ratings, response counts, student comments, and course details are open in every instructor’s profile. Compare them and choose the person you feel comfortable learning with.
