Abstract
Most jurisdictions worldwide have a single specific cut-off date which determines when a student can enter primary school. For example, in Ontario, a child is eligible to enter kindergarten if s/he turns four years old by January 1st of the relevant school year. These cut off dates create a distribution of ages of children within each cohort at school entry, where the oldest child will be approximately one year older than the youngest child. Studies have found that children who are relatively older than their classmates at the beginning of primary school have a variety of short- and medium-run advantages such as scoring higher on standardized exams through primary and secondary school, having higher development of non-cognitive skills, and being less likely to commit a crime as a teenager or an adult. These findings suggest that early differences in maturity can propagate through the human capital accumulation process into later life and may have important implications for adult outcomes and productivity. This presentation will explore the effects of school entry age on children's outcomes and provide evidence on the optimal age to enter primary education.

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.
