Script concordance testing: a review of published validity evidence
Bibliographic record
Abstract
CONTEXT: Script concordance test (SCT) scores are intended to reflect respondents' competence in interpreting clinical data under conditions of uncertainty. The validity of inferences based on SCT scores has not been rigorously established. OBJECTIVES: This study was conducted in order to develop a structured validity argument for the interpretation of test scores derived through use of the script concordance method. METHODS: We searched the PubMed, EMBASE and PsycINFO databases for articles pertaining to script concordance testing. We then reviewed these articles to evaluate the construct validity of the script concordance method, following an established approach for analysing validity data from five categories: content; response process; internal structure; relations to other variables, and consequences. RESULTS: Content evidence derives from clear guidelines for the creation of authentic, ill-defined scenarios. High internal consistency reliability supports the internal structure of SCT scores. As might be expected, SCT scores correlate poorly with assessments of pure factual knowledge, in which correlations for more advanced learners are lower. The validity of SCT scores is weakly supported by evidence pertaining to examinee response processes and educational consequences. CONCLUSIONS: Published research generally supports the use of SCT to assess the interpretation of clinical data under conditions of uncertainty, although specifics of the validity argument vary and require verification in different contexts and for particular SCTs. Our review identifies potential areas of further validity inquiry in all five categories of evidence. In particular, future SCT research might explore the impact of the script concordance method on teaching and learning, and examine how SCTs integrate with other assessment methods within comprehensive assessment programmes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
