Many large-scale performance assessments include score resolution procedures for resolving discrepancies in rater judgments. The goal of score resolution is conceptually similar to person fit analyses: To identify students for whom observed scores may not accurately reflect their achievement. Previously, researchers have observed that…

Rubric scoring has been gaining traction as an emergent method to assess spoken-language interpreting, with two of the most well-known methods being rating scale-based holistic and analytic scoring. While the former provides a single global score, the latter generates separate scores on different dimensions of interpreting performance. Despite the…

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…

Despite the benefits of performance-based oral communication tests, a plethora of variables, as illustrated in Ockey and Li's (2015) model of oral communication assessment, can create construct-irrelevant variance in test scores. In relation to human participants in the oral communication tests, previous studies mostly focused on the direct effect…

Sparse-rated data are common in operational performance-based language tests, as an inevitable result of assigning examinee responses to a fraction of available raters. The current study investigates the precision of two generalizability-theory methods (i.e., the rating method and the subdividing method) specifically designed to accommodate the…

Purpose: The purpose of this paper is to compare two years of results for one state's performance-based assessments for principal licensure Performance Assessment for Leaders (PAL). This includes the field trial (2014-2015) and first year of statewide implementation (2015-2016) when passing score requirements and fees were added. Survey results on…

Previous research in second language writing has shown that when scoring performance assessments even trained raters can exhibit significant differences in severity. When raters disagree, using discussion to try to reach a consensus is one popular form of score resolution, particularly in contexts with limited resources, as it does not require…

This dissertation is comprised of three papers that propose and apply psychometric models to deal with complexities and challenges in large-scale assessments, focusing on modeling rater effects and complex learning progressions. In particular, three papers investigate extensions and applications of multilevel and multidimensional item response…

Assessors' scores in performance assessments are known to be highly variable. Attempted improvements through training or rating format have achieved minimal gains. The mechanisms that contribute to variability in assessors' scoring remain unclear. This study investigated these mechanisms. We used a qualitative approach to study…

This study explores the utility of analytic scoring for TAST in providing useful and reliable diagnostic information for operational use in three aspects of candidates' performance: delivery, language use and topic development. One hundred and forty examinees' responses to six TAST tasks were scored analytically on these three aspects of speech. G…

This study was designed to compare teachers certified in South Carolina that were trained in two different methods: through traditional college preparation programs and through the Program of Alternative Certification for Educators (PACE). This study explored three research questions. The first question addressed differences in pedagogical…

This study illustrates the use of three least-squares models to control for rater effects in performance evaluation: (1) ordinary least squares (OLS); (2) weighted least squares (WLS); and (3) OLS subsequent to applying a logistic transformation to observed ratings (LOG-OLS). The three models were applied to ratings obtained from four…

Differences in the Texas Teacher Appraisal System scores of teacher subgroups over 2 years were examined for 2,366 teachers for scores on individual domains, sums of scores of the 1st 4 domains, and overall summary performance scores, as well as appraiser differences. Implications for teacher evaluation are discussed. (SLD)

Preliminary data was gathered to guide subsequent research that will shape training procedures and scoring practice for performance assessment activities that integrate multiple content areas. Content area integration is a key feature of many of the tasks in the Maryland School Performance Assessment Program (MSPAP), a large-scale assessment of…

Several common sources of error in assessment that depends on the use of judges are identified, and ways to reduce the impact of rating errors are examined. Numerous threats to the validity of scores based on ratings exist. These threats include: (1) the halo effect; (2) stereotyping; (3) perception differences; (4) leniency/stringency error; and…
