Literature Review on Policies to Support Early Childhood Development
Bibliographic record
Abstract
The purpose of this report is to provide an overview of what we know as scientists about the developmental dimensions in early childhood that are particularly predictive of academic achievement and future well-being, the effect of formal child care on development and the barriers to access, and the interventions that can be made with parents to support their development, always with particular attention to the impacts on inequalities of outcomes. It consists of 4 chapters, each of which is the result of a systematic review of the literature. The first chapter will provide a conceptual map of the different dimensions that appear in the literature as particularly important for child development. These dimensions will then serve as a methodological grid for two of the other three chapters, which will systematically refer to them. The second chapter will focus on the effects of formal childcare arrangements on children's development. The third chapter will discuss the barriers to accessing these different forms of formal care, as well as the interventions that can be made to overcome these barriers. Finally, the last chapter will focus on the primary mode of care for children, namely their families. This will be a review of interventions that improve their child's development in each of the key dimensions identified in the first chapter.

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.
