Abstract

fetched live from OpenAlex

PURPOSE: This study investigates (a) whether items within the Multiple-Choice Questions component of the Medical Council of Canada's Qualifying Examination Part I exhibit local dependencies and (b) potential sources of such dependencies. METHOD: The dimensionality of each of six discipline-based subtests was assessed based on exploratory nonlinear factor analyses. A standardized Fisher's z statistic was used to test residual item correlations for local item dependencies. The characteristics of pairs of items flagged as possibly locally dependent were reviewed. RESULTS: Some items in the Pediatrics and Public Medicine/Community Health subtests are locally dependent; these tend to be the more difficult items on the subtests. DISCUSSION: While these results are encouraging, the possible causes and potential impacts of any local dependencies should be investigated further.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
