The main objective of this Methods Showcase Article is to show how the technique of adaptive comparative judgment, coupled with a crowdsourcing approach, can offer practical solutions to reliability issues as well as to address the time and cost difficulties associated with a text-based approach to proficiency assessment in L2 research. We…

For agencies that deliver high-stakes Second Language (L2) proficiency exams, a research agenda has been undertaken for years to examine the role of rater, task, and rubric as sources of variability into their performance assessments (Lee, 2006; Sawaki & Sinharay, 2013; Xi, 2007; Xi & Mollaun, 2006). However, these challenges are more…

In language performance tests, raters are important as their scoring decisions determine which aspects of performance the scores represent; however, raters are considered as one of the potential sources contributing to unwanted variability in scores (Davis, 2012). Although a great number of studies have been conducted to unpack how rater…

The study investigated the alignment process of the International English Language Competency Assessment (IELCA) suite examinations' four levels, B1, B2, C1 and C2, onto the Common European Framework of Reference (CEFR) by explaining and discussing the five linking stages (Council of Europe (CoE 2009). Unlike previous studies, this study used the…

A large data set of L1 psycholinguistic norms (Balota "et al." 2007) was used to assess spoken L2 English lexical proficiency in cross-sectional and longitudinal learner corpora. Behavioral norms included lexical decision and word naming latencies (i.e. reaction times) and accuracies for 40,481 English words. A frequency measure was…

There is emerging evidence that collocation use plays a primary role in determining various dimensions of L2 oral proficiency assessment and development. The current study presents the results of three experiments which examined the relationship between the degree of association in collocation use (operationalized as t scores and mutual…

An assumption underlying speaking tests is that scores reflect the ability to produce online, non-rehearsed speech. Speech produced in testing situations may, however, be less spontaneous if extensive test preparation takes place, resulting in memorized or rehearsed responses. If raters detect these patterns, they may conceptualize speech as…

The aim of the study was to investigate how raters come to their decisions when judging spoken vocabulary. Segmental rating was introduced to quantify raters' decision-making process. It is hoped that this simulated study brings fresh insight to future methodological considerations with spoken data. Twenty trainee raters assessed five Chinese…

The present study discusses the relevance of measures of lexical diversity (LD) to the assessment of learner corpora. It also argues that existing measures of LD, many of which have become specialized for use with language corpora, are fundamentally measures of lexical repetition, are based on an etic perspective of language, and lack construct…

Research in second language speech has often focused on listeners' accent judgment and factors that affect their perception. However, the topic of listeners' application of specific sound categories in their own perceptual judgments has not been widely investigated. The current study explored how listeners from diverse language backgrounds weighed…

Think-aloud protocols (TAPs) are frequently used in research on essay rating processes. However, there are very few empirical studies of the completeness of TAP data and the effects of this technique on rater performance (i.e., rating processes and outcomes). This study aims to start to address this research gap. As part of a larger study on rater…

Second language (L2) oral performance assessment always involves raters' subjective judgments and is thus subject to rater variability. The variability due to rater characteristics has important consequential impacts on decision-making processes, particularly in high-stakes testing situations (Bachman, Lynch, & Mason, 1995; A. Brown, 1995;…
