Of 67 adults who have taken a one-to-one Spanish class with us since 2020, 13% stopped after their first class and 55% went on to take ten or more. Between those two groups sits the moment that decides which one a new student joins, and it arrives much earlier than we expected.
Language learning statistics usually come from apps with millions of users and three-minute sessions. This is a different kind of record: 1,896 real classes, one teacher and one student at a time, sixty minutes each, booked and paid for over six and a half years. It is a small sample by design, because there is no large one.
Key takeaways
- 13.4% of students never take a second class. Nine of 67.
- After that first drop, the curve nearly flattens. Of students who take a second class, 94.8% take a third.
- 71.6% of students reach a fifth class. Of those, 77.1% reach ten or more and 22.9% pass fifty.
- Students who reach ten classes stay a median of 512 days, about 17 months. The longest-running student is at 289 classes across six and a half years.
- Of 70 people who booked a free roadmap consultation, 40 went on to book paid classes, a rate of 57.1%.
The short version
Adult language learning is not a motivation problem spread evenly across a year. It is a decision made in the first two or three weeks and then rarely revisited. Nearly all of our attrition happens at class one. Past class five, students behave like people with a habit rather than people trying something out, and they stay for well over a year.
Why nobody publishes this number
Retention data for adult language learners comes almost entirely from apps, and an app session is not a lesson. Schools that teach one to one hold the relevant records, and they are small, private businesses that have no reason to publish them. We looked for a comparable published figure from another one-to-one school before writing this and did not find one, which is why this study reports its own sample size in every sentence rather than claiming to describe the field.
There is a useful public benchmark for the other half of the question, how much taught time a level takes. Cambridge English publishes guided learning hours per CEFR level: roughly 180 to 200 hours to A2, 350 to 400 to B1, and 500 to 600 to B2. Our committed students, the 37 who reached ten classes, take a median of 33 classes at a median pace of 29.3 classes a year. At that pace, class time alone would take well over a decade to reach the B1 band. That is not a discouraging fact, it is the argument for what happens between classes, and it is why our own teaching puts so much weight on what a student does in the other 167 hours of the week.
What we measured
Our scheduling system holds one record per client with their completed class count, their first and last class dates, and whether they ever booked a free consultation. We exported it, merged duplicate records by email address (the system had 12 duplicate pairs, one person appearing twice under different spellings), and analyzed every person with at least one completed class. That is 67 students and 1,896 classes between January 6, 2020 and July 24, 2026.
How many adults quit after one class?
Nine of 67 students, or 13.4%, never booked a second class. That is the largest single loss anywhere in the data. The next largest is the step from class four to class five, where five students stop. Restricting the sample to students whose first class was at least 180 days before our data cutoff, which removes anyone too new to have had the chance, the figure barely moves: 14.1% of 64 students.
What the record cannot tell us is why. Our scheduling data holds no exit reason, and it would be easy and dishonest to fill that gap with a story about motivation. What we can see is timing, and timing points at the first three weeks.
What happens after the second class
Students who book a second class almost always book a third: 94.8% of them. The continuation rate stays above 90% at nearly every step from there to class twelve. In plain terms, the question is not whether a student will stay for a year. The question is whether they come back once.
| After class | Students who reached it | Took the next one | Continuation rate |
|---|---|---|---|
| 1 | 67 | 58 | 86.6% |
| 2 | 58 | 55 | 94.8% |
| 3 | 55 | 53 | 96.4% |
| 4 | 53 | 48 | 90.6% |
| 5 | 48 | 44 | 91.7% |
| 10 | 37 | 34 | 91.9% |
The full table to class twenty is in the CSV.
How long does an adult actually study?
Among students who reach ten classes, the median relationship lasts 512 days, about 17 months. The mean is 629 days, pulled up by students who have been with us since 2020. The longest is 2,388 days and 289 classes, one person.
That number is the one we wish every adult knew before they started. The marketing of language learning runs on thirty-day challenges. The actual shape of getting comfortable in a second language, at one hour a week with a teacher, is measured in years, and the students who get there are not the intense ones. They are the ones who kept a weekly slot through two vacations and a busy season at work.
Does a free consultation convert?
Seventy people have booked our free roadmap consultation and 40 of them went on to book paid classes, a rate of 57.1%. We offer it because adults arrive embarrassed about their level and want to know what a realistic plan looks like before they pay for anything. The conversion rate suggests that a structured first conversation about goals and level does most of the work that a sales page usually tries to do.
Where adult students come from
Of the 14 prospective students who filled in our intake form, 11 said they found us through Google search. One came from Instagram, one from a friend, and one from somewhere else. Fourteen responses is far too small a sample to publish as a rate, and we are including it because the direction is worth knowing next to the search data in our zero click study: almost everybody arrives through a search engine that now sends us 0.19% of the people it shows us to.
The same fourteen forms record what people expect to spend on lessons each month. Six said $50 to $149, four said $250 or more, three said $150 to $249, and one said under $50. Again, fourteen answers, so treat it as a shape rather than a statistic.
Six cohorts, one consistent pattern
Every yearly cohort since 2020 has sent at least 58% of its students past class five. The 2020 group, eleven students who started when the world moved indoors, is the strongest at 90.9%, and it is also the group with the most time to accumulate classes. Later cohorts are smaller because the school moved toward fewer students at more hours each.
| First class in | Students | Classes taken | Reached class 5 | Reached class 10 |
|---|---|---|---|---|
| 2020 | 11 | 753 | 90.9% | 63.6% |
| 2021 | 7 | 139 | 71.4% | 57.1% |
| 2022 | 12 | 145 | 58.3% | 50.0% |
| 2023 | 14 | 366 | 71.4% | 57.1% |
| 2024 | 12 | 380 | 75.0% | 66.7% |
| 2025 | 5 | 33 | 60.0% | 40.0% |
| 2026 | 6 | 80 | 66.7% | 33.3% |
The 2025 and 2026 rows are still filling. A student who started in March cannot have taken fifty classes yet, so read those two rows as incomplete rather than as decline.
What we changed because of it
We rebuilt the first month. A new student now leaves the first class with something they can say to a real person that week, not with a grammar overview, because the data says the first class is the whole decision. We also book the free consultation before anyone pays, since more than half of those conversations turn into a student and the ones that do not usually reveal a mismatch we would rather find early. The fifth class is now a deliberate checkpoint where we look at what has changed since class one.
How we counted this
Source: the Speak Better Spanish class ledger, built from our scheduling system’s client list. One record per client with completed class count, consultation count, first and last class dates.
Window: January 6, 2020 to July 24, 2026, the date of the most recent completed class in the export.
Sample: 138 client records, merged to 126 unique people by email address (12 duplicate pairs), of whom 67 have at least one completed class. 1,896 completed classes. Consultations, workshops and immersion trips are excluded from the class count.
Definitions: a “student” is a person with at least one completed one-to-one class. “Continuation rate” at class n is the share of students reaching class n who also reached class n+1. “Tenure” is the number of days between a student’s first and most recent class. A committed student is one with ten or more completed classes.
Intake form: the acquisition and budget figures come from 14 completed intake forms, a separate and much smaller dataset, and are labeled as such in the text. The form does not ask about level or prior study, so we have nothing to publish on either.
Limits: 67 students is a small sample and every percentage here moves by more than a point when one person changes category. The ledger records no reason for leaving, so nothing in this study explains why anyone stopped. Students who started recently are still accumulating classes, which pulls the most recent cohorts down; the censored sample described above is our check on that. All figures are aggregate and anonymized.

Questions people ask about this data
What percentage of adults quit language lessons after the first one?
In our school, 13.4%, or nine of 67 students since 2020. We have not seen comparable published figures from other one-to-one schools, which is part of why we published ours. Treat it as one school’s rate, not an industry number.
How many lessons does it take before a student sticks?
Five is where the risk drops sharply in our data. 71.6% of students reach a fifth class, and of those, 77.1% go on to ten or more. The step that actually matters most is smaller than that: booking a second class at all.
How long do adults keep taking Spanish classes?
Among our students with ten or more classes, the median is 512 days from first class to most recent, about 17 months. The mean is 629 days. One student has been with us for 2,388 days and 289 classes.
Do free consultations actually turn into students?
For us, 57.1% of the time. Forty of the 70 people who booked a free roadmap consultation went on to book paid classes. We do not run the consultation as a sales call, which we think is why it works, but that is an opinion and the 57.1% is the measurement.
