In a recent state-of-the-art (SoA) article (Stoynoff 2009), I reviewed some of the trends in language assessment research and considered them in light of validation activities associated with four widely used international measures of L2 English ability. This Thinking Allowed article presents an opportunity to revisit the four broad areas of L2 assessment research (conceptualizations of the L2 construct, validation theory and practice, the application of technology to language assessment, and the consequences of assessment) discussed in the previous SoA and to propose tasks I believe will promote further advances in L2 assessment. Of course, the research tasks I suggest represent a personal stance and readers are encouraged to consider additional perspectives, including those expressed by Bachman (2000), Chalhoub-Deville & Deville (2005), McNamara & Roever (2006), Shaw & Weir (2007), and Stansfield (2008). Moreover, readers will find useful descriptions of current research approaches to investigating L2 assessments in Lumley & Brown (2005), Weir (2005a), Chapelle, Enright & Jamieson (2008), Lazaraton (2008), and Xi (2008).
On the value of homogeneous constructs for construct validation, theory testing, and the description of psychopathology.
