Our freely accessible test consists of 90 items and is designed for L2 speakers of Estonian. LexEst is modeled after the original Lexical Test for Advanced Learners of English. Similarly to other test variants, our test has been adapted to assess vocabulary knowledge at varying proficiency levels. Our findings demonstrate that LexEst provides an objective measure of the Estonian vocabulary of L2 learners, aligning well with subjective language proficiency indicators, such as self-assessed skills. In addition, higher LexEst scores and shorter response times are associated with higher CEFR-level language courses and a greater daily use of Estonian. Higher LexEst scores are also associated with an earlier age of acquisition in Estonian and a higher perceived importance of learning Estonian.  \nKeywords: Estonian; language proficiency; lexical decision; response times; vocabulary  \nIntroduction  \nEstonian is a Finno-Ugric language of the Uralic language family, with approximately 1.1 million native speakers (L1) . Furthermore, according to the 2021 census, 1 a considerable part of the population in Estonia (about 17%) speaks Estonian as a second language (L2). This number is expected to grow in the coming years as Estonia transitions from a country with a negative net migration rate to one with a steady inflow of migrants who need to learn Estonian as an L2 . Additionally, Estonian schools are in transition from Russian and Estonian medium education to only Estonian medium education. With the increasing number of Estonian L2 speakers comes the need for researchers and educators to find means to measure Estonian language proficiency reliably. However, at the moment, there is no quick and easy way to achieve this. The current study introduces the Estonian version of  \n© The Author(s), 2025 . Published by Cambridge University Press.

It offers a quick and easy way to measure learners’ proficiency through vocabulary assessment.  \nSo far, Estonian language skills, including vocabulary, have been measured via CEFR-level testing2 in schools and by the Education and Youth Board. Regarding freely available assessment options, the Estonian Integration Foundation3 offers online screening and diagnostic tests, allowing language learners to assess their Estonian knowledge by themselves. They include, among other skills tests, a vocabulary assessment test.
