An empirically derived, binary-choice, boundary-definition scale (EBB scale; Turner, 2001; Turner& Upshur, 1996; 2002; Upshur &Turner, 1995) consists of an ordered set of binary questions which guides raters through the decision-making process. As opposed to scales based on theorised or hypothesised language levels, EBB scales are empirically developed with reference to sets of authentic learner or test taker performance samples. Research on the original EBB scales has demonstrated their efficiency, their high degree of inter-rater reliability, and their accessibility for raters of varied backgrounds. While some scholars have attested to the benefits of EBB scales(e.g., Hirai & Koizumi, 2013; Plakans, 2013; Ewert & Shin, 2015), language assessment professionals are less familiar with the format and development process of this scale compared to other types, as well as the potential of this scale option for their contexts.This proposed workshop would give participants the chance to learn more about EBB scales, to try using them, and to draft their own, making use of authentic performance samples.

Participants will be introduced to the concept of dimensionality in language tests. They will learn how dimensionality of language tests can be examined through confirmatory factor analysis.They will also learn how to run different models of confirmatory factor analysis using the “lavaan” package in Randhow to interpret the out put suchas what model best represents the factor structure of a language test.
Gholam Hassan Khajavy (PhD) is Assistant Professor of Applied Linguistics at the University of Bojnord, Iran. His main research interests are the psychology of language learning and research methods in Applied Linguistics. He uses advanced statistical procedures such as structural equation modelling, multilevel modelling, and latent growth curve modelling in his research. He is the consulting editor of Educational Psychology (Routledge) and has recently co-edited a special issue on the role of grit among language learners which was published in the Journal for the Psychology of Language Learning. He has conducted several workshops on conducting structural equation modelling and multivariate statistics in different universities. Moreover, he has published in different international journals such as TESOL Quarterly, Studies in Second Language Acquisition, Language Learning, and Contemporary Educational Psychology.
David Wei Dai, PhD, FHEA (Monash University) completed a PhD on assessing interactional competence where he proposed the Sequential-Categorical Analysis approach. He has developed a publication record on this topic, including journal articles, an edited special issue, book chapters, a monograph under contract with Peter Lang, and a second book project currently under external review with Routledge. He has been invited to give talks on assessing interactional competence by universities in Australia,the UK, Norway, and China. He also delivers training workshops to industry partners on this topic.
