TL;DR: "Fluent in eight weeks" is a promise about someone else's effort. Show what past learners did instead: dated exam results with the number who sat, level changes with the taught hours and homework behind them, tasks learners can now do, and their own words with written consent. State the time a level step usually takes in your school, and follow the rules on reviews and testimonials.
A parent calls a language school in March. Her daughter needs B2 for a university application and the exam is in June. "Can you get her there?" The owner looks at the school's own advertising, which says "Reach your goal level in 12 weeks", and realises she cannot say yes honestly. The daughter's current level is unknown, and so is how much she will practise.
How do you show results without promising fluency in weeks? You show what has happened, with its conditions, instead of what will happen. This article covers why time promises are a risk, the proof formats that stay honest, how to state time and effort, the rules on reviews and testimonials, and a list of phrases to replace. It is part of our guide to language school marketing in the age of AI.
Why are "fluent in X weeks" promises a problem?
Because the result depends on the learner, not only on the school: their starting level, the hours they attend, the practice they do and the skill measured. A time promise ignores all four. It also draws the kind of attention that consumer authorities pay to language-learning marketing, and it disappoints the learners who believe it.
The Hungarian competition authority (GVH) opened proceedings against a language-learning app in September 2025. Among the questioned practices were an unfounded "best" slogan and a misleading result promise ("9 out of 10 after 1 month"), along with unclear information about the free version and pressure messages; opening proceedings does not mean an infringement was found (Telex, 2025).
Accreditors set the same bar from another direction. Accreditation UK criterion M22 requires all publicity to be accurate and give realistic expectations about premises, location and services, and inspectors read it to include photos, videos and the school's social media (English UK / British Council, 2019). A result promise is an expectation; it has to be realistic.
What counts as honest proof of results?
A result that names who, from where, with what effort, measured how, and when. Five formats meet that test: dated exam results with the number of candidates, level changes with taught hours, tasks learners can now do, learners' own words with consent, and your own completion figures. Each needs its conditions written next to it.
| Format | What it must include | Example of the wording |
|---|---|---|
| Exam results | Exam, level, date, how many sat and how many passed | "June session: 9 of our 11 candidates passed the B2 exam." |
| Level change | Start and end level, taught hours, test used | "B1 to B2 on our end-of-course test, after 72 taught hours and homework." |
| Task achieved | What the learner can now do, in their words | "I presented our quarterly report in English for the first time." |
| Learner story | Start, effort, now, date, consent | Five lines, with a first name and the month |
| Completion | Share of learners who finished the course | "Of 40 learners who started in September, 33 finished." |
Two rules make these formats honest. Show the whole group, not the star learner: "9 of 11" tells the reader more than one star pupil. And date every result, so nobody mistakes last year's group for a promise about next term's.
For the learner-story format, the template and the consent steps are in adult education marketing ideas.
How do you state time and effort honestly?
From your own records, as a range with its conditions: "learners who moved from B1 to B2 in our groups needed between this many and that many taught hours, plus about an hour of homework a week." That sentence answers the parent's question better than any promise, and you can prove it.
The calculation needs only your attendance and test records:
- List the learners who completed a level step in the last two years (for example B1 to B2 on your end-of-course test).
- For each, add up the taught hours they actually attended.
- Note the lowest and highest values, and the middle value.
- Write the range, the condition (homework, attendance) and the test you used.
Example (illustrative, not a real case): a school finds 18 learners who moved from B1 to B2 on its end-of-course test in two years. Their attended hours run from 64 to 140, with a middle value of 96, which is about two and a half terms of two evenings a week. The website now says: "In our evening groups, learners who moved from B1 to B2 attended between 64 and 140 taught hours, about 96 for most, and did roughly an hour of homework a week." To the parent in March, the owner can now say: "From B1, June is unlikely for most learners; let's test her level first and look at an intensive option."
What are the rules on reviews and testimonials?
Ask everyone, reward no one, write nothing yourself, and keep proof of consent. Platforms remove reviews from staff and from selective campaigns, Hungarian and US law ban fake or unverified reviews, and accreditors expect evidence that a learner agreed to be quoted. All four point to the same routine.
- Google. Google removes conflict-of-interest reviews, such as those from current or former employees, and bars selectively soliciting positive reviews (Google Maps contribution policy, 2026). Teachers should not review their own school, and the request goes to every learner, not only the happy ones.
- Hungary. The Unfair Commercial Practices Act blacklists claiming that reviews come from real customers without checking it, and writing or commissioning fake reviews (Fttv. annex, points 34–35).
- United States. The FTC's 2024 rule bans fake and AI-generated reviews, buying positive or negative sentiment, undisclosed insider reviews and review suppression (FTC, 2024).
- Accreditation. Good practice under Accreditation UK criterion M22 is testimonials and student videos backed by evidence of permission (same Accreditation UK source as above).
If you show reviews on your site, say where they come from and do not hide the critical ones. A page with only five-star quotes looks selected, because it is.
Which phrases should you replace?
Any phrase that promises a result, a speed or a qualification. Replace each with the fact behind it: hours, level, test, date. The table below covers common examples; use it to check your own site, your ads and your agents' brochures.
| Promise | Honest version |
|---|---|
| "Fluent in 8 weeks" | "Eight weeks, 32 taught hours, focused on speaking at work" |
| "You will pass your exam, we promise" | "June session: 9 of our 11 candidates passed" |
| "Reach B2 in one term" | "One term covers part of the step from B1 to B2; see our hours range" |
| "Learn faster than anywhere else" | "Two evenings a week, homework set and checked by your teacher" |
| "Certified course" | "You receive a certificate of attendance; the language exam is separate" |
| "Every learner succeeds" | The real figure, with the number of learners and the date |
The "certified" row touches a legal line in Hungary. Under the Adult Training Act, advertising and information material may not use a training name identical to a vocational qualification, and may not refer to a qualification the course does not give (Fktv. 17/A. §); the register number belongs on the training documentation and the documents you issue (Fktv. 17. § a)) (Fktv., Nemzeti Jogszabálytár, 2026). A course certificate is not an accredited language exam, and the page should not blur the two.
Check what your education agents publish too. Their brochures and social media speak for you, and under Accreditation UK good practice the school monitors agents' materials and social media (English UK / British Council, 2019).
Action plan: a one-afternoon results audit
Open your website, your last three ads and any agent brochure, and mark every result claim. For each, either replace it with a dated fact from your records or delete it. Then build one results page with the formats above, and link it from every course page.
- Search your site for "fluent", "promise", "fast", "weeks", "every learner" and "certified".
- Replace each hit with a fact from the phrase table, or delete it.
- Pull the last two exam sessions' results and the hours range for one level step.
- Ask three learners for a story with written consent.
- Publish one results page and link it from each course page.
- Set a date to update it after the next exam session.
For the course descriptions that sit beside these results, use the course description template; for answering applicants who ask about AI, see why pay for language lessons when there is ChatGPT. The wider picture is in the language school marketing guide.
If you want prompts and checklists for honest results pages, course pages and ads, we are building the Conversion Copywriting Pack. Get notified when it launches.
FAQ
Can a language school say how long it takes to reach a level?
Yes, if you state it as a range from your own records, with its conditions. Count the taught hours that past learners attended to move one level on your test, and give the lowest, highest and typical values, plus the homework involved. That is a fact about past learners, not a promise about the next one, and you can show how you got it.
Is it allowed to publish exam pass rates?
Yes, if the figure is true, dated and complete. Say which exam, which session, how many of your learners sat it and how many passed. Do not leave out learners who failed or count only those you advised to sit. A small, honest number such as nine out of eleven is more convincing than a round claim nobody can check.
Can teachers leave Google reviews for their own school?
No. Google removes conflict-of-interest reviews, including those from current or former employees, and in Hungary and the US fake or unverified reviews are banned practices. Ask every learner at the end of a course, the same way, with a review link or QR code, and let teachers reply to reviews on the school's behalf instead.
