Paula Winke is a Professor of Second Language Studies and TESOL at Michigan State University, USA, where she specializes in the assessment of language proficiency for practical uses and the measurement of individual differences for SLA research.Tineke Brunfaut is a Professor of Linguistics and English Language at Lancaster University, UK, where she specializes in language testing and second language reading and listening.

"The Handbook of SLA and Language Testing is a wonderful volume that shows how SLA and language testing combined into one transdisciplinary research space has incredible power to move L2 learning theory into solid, new, and exciting grounds. Paula Winke and Tineke Brunfaut's stewardship over the chapters in this volume has given rise to a Handbook that will be read, consulted, and cited for years to come."--Jamie Schissel, University of North Carolina, USA.
