Abstract
This study sought to determine if Canadian Dental Aptitude Test Perceptual Ability (PA) and Carving Dexterity (CD) scores have any practical utility as predictors of psychomotor performance. Simple linear regression and multiple regression analyses were performed and prediction intervals plotted. Efforts were made to expand the range of the predictor and dependent variables and to improve the accuracy and consistency and prevent contamination of the dependent variables. Results for both PA and CD varied markedly across years. Weak, but statistically extremely significant, correlations were observed for both PA and CD with specific technique grades and the year-overall pooled data. PA correlations loaded on exams at the start, and CD correlations loaded on exams at the end of the year. Manual average scores exhibited the strongest correlation with year-overall technique grades, but could explain no more than 7.2 percent of observed variance. Prediction intervals for year-end grades spanned at least 38 percentage grade points for both PA and CD. Within the context of the present study, PA and CD scores demonstrated no practical utility as predictors of psychomotor performance.

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
