Alina Anca von Davier (born September 11, 1967) is a psychometrician and researcher in computational psychometrics, machine learning, and education. Von Davier is a researcher, innovator, and an executive leader with over 20 years of experience in EdTech and in the assessment industry. She is the Chief of Assessment at Duolingo, where she leads the Duolingo English Test research and development area. She is also the Founder and CEO of EdAstra Tech, a service-oriented EdTech company. In 2022, she joined the University of Oxford as an Honorary Research Fellow,[1] and Carnegie Mellon University as a Senior Research Fellow.[2]

Education

Von Davier completed a M.S. in Mathematics from the University of Bucharest in 1990. In 2000, she earned a doctorate in mathematics from Otto von Guericke University Magdeburg.[3] In 2019 she completed classes in an Executive MBA program at Harvard Business School.

Career

As one of the pioneers of the field of computational psychometrics, von Davier has dedicated her career to advancing the field through her work in both academia and industry. She served as Chief Officer at ACT (test) leading ACTNext, an R&D-based innovation division. Prior to this, she worked for 15 years at Educational Testing Service, where her latest position was Senior Center Director. In 2020, she left her position at ACT and joined Duolingo as Chief of Assessment for the Duolingo English Test.[4]

Von Davier has made significant contributions to the field of psychometrics through her work in academic settings. She was the Chair of the Editorial Council of the Psychometric Society,[5] and an associate editor of Psychometrika. She also served as guest editor for both Applied Psychological Measurement and the Journal of Educational Measurement.[6][7] In 2022 she served as the Chairperson of the global board of directors for the Association of Test Publishers, and was the president of the International Association of Computerized Adaptive Testing from 2019 to 2022.

Von Davier was a member of the Board of Directors for Smart Sparrow, an adaptive learning company from 2018 to 2020. She currently serves as a Director on the Board for MACAT, an education company focused on critical and creative thinking, learning and assessment.

She currently sits on the global board of directors for the Association of Test Publishers and is the president of the International Association of Computerized Adaptive Testing.[8]

Recognition

Von Davier’s work has been widely recognized in the academic community. In 2019, she was a finalist for the Innovator award from the EdTech Digest.[9] In 2020, she received ATP’s Career Award for her contributions to assessment.[10] The American Educational Research Association awarded her the Division D Signification Contribution Educational Measurement and Research Methodology Award for her publications “Computerized Multistage Testing: Theory and Applications” (2014) and an edited volume on test equating, “Statistical Models for Test Equating, Scaling, and Linking” (2011).[11] In 2022 she received the National Council on Measurement in Education's Bradley Hanson award for her work on adaptive testing and for the co-authored book on computer adaptive testing with R.[12]
