Vocabulary underpins reading, writing, speaking, and listening, while academic vocabulary forms a central part of students’ academic literacy. This paper presents the design and initial validation of the Productive Academic Vocabulary Test, a new instrument that closely follows the Productive Vocabulary Levels Test but uses updated definitions and scoring principles. Validation with 232 participants at three Swedish universities shows the test differentiates knowledge levels and provides nuanced measurement.

Vocabulary is a key aspect of language proficiency, underpinning the four skills of reading, writing, speaking and listening. In academic contexts, of particular importance is academic vocabulary, the part of the lexicon which is better represented in academic than in general discourse, and which constitutes a key dimension of students’ academic literacy. The present paper details the design and initial validation of a new test of controlled productive knowledge of English academic vocabulary. The test design closely follows that of the Productive Vocabulary Levels Test (Laufer & Nation, 1999) but the new instrument – named the Productive Academic Vocabulary Test – uses a different basis for defining academic vocabulary and employs an updated set of scoring principles. The test was validated using scores from 232 participants at three Swedish universities. Findings indicate that the test can discriminate levels of knowledge of English academic vocabulary amongst the target population and that the scoring principles provide a nuanced measure of vocabulary knowledge. Pedagogical and research implications are discussed.  \nKeywords: academic vocabulary; vocabulary testing; language education; Productive Academic Vocabulary Test (PAVT); English for academic purposes (EAP)  \nEtt test av kontrollerad produktiv akademisk engelskordkunskap  \nSammanfattning  \nAv både pedagogiska skäl och för forskningsändamål är testning och utvärdering av språkfärdighet ett viktigt område inom språkdidaktik. Ordkunskap är en central dimension av språkfärdighet eftersom den ligger till grund för samtliga fyra färdigheter: läsa, skriva, tala och lyssna. I akademiska sammanhang är det särskilt viktigt att ha ett akademiskt ordförråd, det vill säga ord som förekommer oftare i akademisk diskurs än  \ni allmänna sammanhang. Denna artikel beskriver utvecklingsprocessen för att skapa och validera ett nytt test för kontrollerad produktiv engelsk akademisk ordkunskap.  \nTestformatet följer Productive Vocabulary Levels Test (Laufer & Nation, 1999), mendetta nya test, benämnt Productive Academic Vocabulary Test, använder en annan definition av akademiskt ordförråd och ett mer nyanserat sätt att bedöma testsvar. Testet validerades med resultat från 232 deltagare vid tre svenska universitet. Resultaten visaratt testet kan mäta olika grader av ordkunskap hos deltagare och att bedömningsprinciperna ger en nyanserad bild av ordkunskap.
