Protocol for a Systematic Review of the Impact of Test Preparation Practices on L2 Test Performance and Language Proficiency
Bibliographic record
Abstract
Every year, millions of second language (L2) learners worldwide invest substantial time and resources in preparing for high-stakes language proficiency tests, the outcomes of which significantly influence crucial decisions regarding their educational pursuits, career opportunities, and immigration prospects. Learners’ performance on such tests is intrinsically linked to their test preparation practices which are affected by various factors; however, the efficacy of these practices remains a subject of debate and requires a systematic investigation. To examine the characteristics of test preparation influencing its effectiveness and to determine the extent to which test preparation practices affect L2 learners’ language test performance and language proficiency, we will conduct a systematic review of 24 primary studies that have investigated these issues. Guided by four review questions, this systematic review will follow the PRISMA guidelines to provide a comprehensive examination of the research methodologies and key findings of the primary studies. By carrying out this investigation, we hope to offer valuable insights that can potentially inform more effective test preparation practices, test design considerations, and future directions for research in this domain.

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.
