While CJ produces valid and reliable results, it often requires many judgments before quality scores become reliable. In this study, we examine whether natural language processing (NLP) can improve the efficiency of CJ by warm-starting the estimation of quality scores and the selection of essay pairs. We predict essay quality by fine-tuning a transformer model and use these predictions to construct informative priors in a Bayesian Bradley-Terry-Luce model. We then introduce three selection rules based on predicted scores and essay embeddings. In this study, we focus on Dutch writing assessments in secondary and higher education in two settings: one-off assessments and recurrent assessments. Warm-start estimation reduced the number of judgments required to reach a reliability of .70 by approximately 40%-68% compared with likelihood-based cold-start estimation and by approximately 24%-64% compared with Bayesian cold-start estimation. To reach a reliability of .90, warm-start estimation yielded smaller reductions of around 15% compared with cold-start estimation. The warm-start selection rules we constructed yielded smaller additional gains. In practice, a reliability of .70 was reached after two to four judgments per essay, and a reliability of .90 after seven to fourteen judgments.

We compare a modern Transformer encoder, ModernBERT, with a linear-time state-space model, Mamba-130M, which supports efficient long-context processing. Evaluation follows the standard framework for the evaluation of automated scoring using Quadratic Weighted Kappa, exact agreement, and standardized mean difference.

By contrast, the state-space model shows favorable distributional behavior and much lower inference latency as sequence length grows, while maintaining competitive scoring performance.

This article distinguishes three such quantities in item response theory (IRT) scoring: the conditional standard error (CSE), which summarizes variability of a reported estimate under repeated measurement at fixed proficiency; the posterior standard deviation (PSD), which summarizes uncertainty about proficiency conditional on observed responses; and the conditional standard error of prediction (CSEP), which summarizes uncertainty in a future reported estimate under specified future administration, scoring, and reporting conditions. The central argument is that uncertainty summaries should be defined by their random quantities, conditioning, and intended uses, with estimation guided by those definitions. CSEP receives particular attention because it is less commonly discussed in operational IRT scoring. Building on classical test theory's standard error of prediction and Bayesian posterior predictive ideas, CSEP is defined as the standard deviation of the posterior predictive distribution of a future reported estimate produced by the operational reporting rule. A posterior predictive Monte Carlo/parametric bootstrap procedure is described for estimating CSEP under arbitrary scoring and reporting rules, with a nested law-of-total-variance extension for decomposing predictive uncertainty into future measurement variability and propagated proficiency uncertainty.

However, the relative behavior of RDIF compared with more flexible residual-based procedures remains unclear, especially under less ideal conditions such as shorter tests, skewed ability distributions, sample imbalance, difficult item profiles, and nonlinear DIF. The present study compares three complementary procedures within a unified residual-based framework: RDIF as a parametric method, spline likelihood-ratio (Spline-LR) as a semi-parametric method, and mutual information (MI) as a nonparametric method. Two simulation studies were conducted in a two-group DIF setting. The first adapted standard RDIF benchmark conditions, whereas the second served as a targeted stress test. Across the simulations, RDIF provided a strong and robust benchmark, showing stable error-control behavior under both conventional and less ideal conditions. Spline-LR and MI showed higher sensitivity under some complex DIF conditions, but these gains were accompanied by substantial losses in specificity and precision.

Such methods may be inadequate when examinees exhibit multiple behavioral transitions during a test. This study developed a multiple change-point detection method for response behavior based on the Pruned Exact Linear Time (PELT) algorithm. To address the limitations of fixed penalty criteria in balancing detection power and Type I error control, this study employed an adaptive penalty calibration method based on the false-positive rate.
