Duolingo published Q3 results last week. Revenue from the Duolingo English Test amounted to $9,649,000 for the quarter. If we divide that number by the cost of taking the test ($70) we get a total of 137,842 tests for the quarter. That’s a decline of 17% compared to the same quarter last year. This figure tracks with what we’ve seen so far this year: Q1 was down 17% and Q2 was down 12%.
Just keep in mind that this is a rough estimate, as some people pay less for the test by purchasing a bundle and others pay more for the test by purchasing express scoring. Others pay nothing at all by using a waiver from the Duolingo Access program (25k waivers were distributed last year).
How does this compare to the industry as a whole? By my data, PTE volumes were down 10% in the first half of 2025, while IELTS volumes at IDP were down 11% for the first half of 2025.
IDP will publish a new half-year report in February.
We might learn about IELTS volumes at the British Council if they publish their annual return in January, as required (but they probably won’t). ETS doesn’t publish TOEFL test volumes, but keep an eye out for the release of the organization’s annual audit in early January.
