Abstract
The recent increase in the use of constructed-response items in educational assessment and the dissatisfaction with the nature of the decision that the judges must make using traditional standard-setting methods created a need to develop new and effective standard setting procedures for tests that include both multiple-choice and constructed-response items. The Body of Work (BoW) method is an examinee-centered method for setting cut-scores that applies a holistic approach to student work in order to estimate the cut-scores that differentiate examinees according to their level of performance in situations where both item formats are used. A detailed review of Version 1 and the recent modification, Version 2, are first presented followed by a critical evaluation of the two versions in terms of Berk’s (1986) 10 criteria for defensibility. The results reveal that the BoW method appears to be a promising method for setting cut-scores that could be used on a wider scale in Canada. However, as with other methods, the experience gained from using the BoW method in the field will probably lead to further modifications in an attempt to increase efficiency without sacrificing accuracy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
