Abstract
This article explores an approach for test score validation that examines test takers’ strategies for taking a reading comprehension test. The authors formulated three working hypotheses about score validity pertaining to three types of test-taking strategy (comprehending meaning, test management, and test-wiseness). These hypotheses were formulated in terms of the use of three types of test-taking strategy and their relationships with performance on specific task types (testlets) and overall test performances. We illustrated the proposed method for validation using example data from the Canadian English Language Proficiency Index Program-General (CELPIP-General) reading pilot test. The findings were that (a) test takers were engaging more in processing the texts for comprehending meaning, less in test-management skills, and least in test-wiseness; (b) at the task level, task characteristics (e.g., difficulty) had implications on test takers’ engagement with different types of strategies, which, in turn, led to differences in predicting task performances; and (c) at the test level, higher engagement in comprehending meaning led to higher test performance, engagement in test management showed a small negative association with test performance, and higher engagement in test-wiseness led to poorer performance. The high congruence between the working hypotheses and the empirical results offered plausible evidence that supported the validity of CELPIP-General reading scores. Revisions to both hypotheses and research design that might improve the proposed validation method are reviewed in the “Discussion” section.

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.
