Abstract
Objectives Ultrasound departments in Canada frequently reduce patient bookings to support student training, which impacts not only patient care but also revenue generation. Therefore, physicians and employers are reluctant to host student sonographers, and educational programs struggle to find sufficient clinical placements for their students. Two research questions were investigated: (1) Can a pair scanning technique effectively integrate the student sonographer into the workplace without impacting patient volumes? (2) Does the pair scanning technique prepare the student sonographer for entry‐level practice faster than traditional practice? Methods This research project was divided into 2 phases. The first phase used action research to develop the pair scanning protocol at a single site with a single preceptor and student. The second phase used a mixed methods approach to test the transferability of the pair scanning protocol across multiple sites, preceptors, and students. Results In phase 1, the student sonographer performed a greater number of total examinations than the rest of her cohort (who were at different placement sites), and the higher performance of independent examinations by the student sonographer under the pair scanning technique was statistically significant [H (4) = 36.297; P < .01]. In phase 2, the pair scanning group and the control group performed equally, with no statistically significant differences. Conclusions The pair scanning protocol is effective at integrating the student sonographer into the work flow without impacting patient care. It prepares the student sonographer for entry‐level practice equally with traditional practice and may be most effective with the weak to average student.

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
