The researchers organized parental influence into five distinct constructs grounded in Developmental Systems Theory: parental characteristics such as age, ethnicity, and marital status; the home learning environment, meaning the structural resources and routines that surround a child; parental involvement, defined as direct behavioral engagement like shared reading, storytelling, and educational play; parent-teacher collaboration, the bidirectional partnership between families and schools; and socioeconomic status, encompassing income, education, and occupational standing. The theory frames development as the dynamic interplay of genetic, environmental, biological, and cultural factors, with parents providing the knowledge, resources, and supportive conditions that prepare children for formal schooling.

The search strategy was exhaustive. Following the PRISMA guidelines, the team queried Web of Science, Scopus, and ProQuest for studies published between 2016 and 2025, initially retrieving 22,906 records. After removing duplicates, screening titles and abstracts, and conducting full-text reviews with inter-rater reliability reaching a Cohen’s kappa of 0.97, only 26 studies survived. Eligible studies had to examine children aged two to eight, include at least one parental or household predictor, and assess school readiness across at least three dimensions such as early literacy, numeracy, and writing. The included samples ranged from 65 to 11,326 participants and spanned North America, Central Europe, Latin America, the Middle East, East Asia, and Africa.

Methodological rigor anchored the analysis. The researchers converted correlation coefficients and standardized regression weights into a common metric using Fisher’s z transformations, applied inverse-variance weighting so that large-sample studies carried proportionate statistical weight, and employed random-effects models to account for genuine variation across studies. Publication bias was checked with Begg’s and Egger’s tests, and sensitivity analyses confirmed that no single study distorted the pooled estimates. Non-significant associations were retained and coded as zero, ensuring that the synthesis did not silently inflate positive findings.

The headline result is striking in its simplicity. Parental involvement showed the strongest association with school readiness, with a pooled effect size of r = 0.21 (95% confidence interval: 0.12 to 0.29, p < 0.001), a small-to-moderate but highly robust correlation. Socioeconomic status and the home learning environment tied for second at r = 0.17 each, followed by parent-teacher collaboration at r = 0.135 and parental characteristics at r = 0.108. When all five factors were combined across the full set of 26 studies, the pooled effect was r = 0.157, with every included study reporting a positive correlation ranging from 0.04 to 0.34. In plain terms, the everyday things parents do reading books, telling stories, playing educational games consistently outperform demographic advantage as predictors of whether children arrive at school prepared.

This finding carries real weight because it challenges a persistent narrative that a child’s academic trajectory is largely fixed by family income. SES certainly mattered, and the mechanism is intuitive: higher-income and better-educated parents can purchase learning materials, access enriching opportunities, and enjoy the time and emotional bandwidth for daily learning. But the meta-analysis shows that engagement, the proximal process of parent and child interacting over shared activities, exerts a stronger direct effect. Under Developmental Systems Theory, this fits precisely: SES and parental characteristics operate indirectly, creating conditions that make close interactions possible, while involvement is the interaction itself. Children’s development, the evidence suggests, depends most on the quality and frequency of those everyday encounters.

The moderation analyses added a second surprise. Child age significantly and negatively moderated the effect of parent-teacher collaboration (r = −0.171, p = 0.011), meaning that the benefit of family-school partnership diminishes as children grow older. Young children entering preschool appear to profit most when parents and teachers coordinate closely, attending meetings, volunteering, and communicating about progress, while older children, perhaps gaining independence in their learning, require less of it. This gives educators a concrete developmental window: structured collaboration programs, such as the Getting Ready for School intervention cited in the review, should be concentrated in the earliest years rather than spread thin across elementary education.

Gender produced a subtler pattern. Child gender significantly moderated the relationship between parental involvement and school readiness (r = −0.161, p = 0.019), indicating that boys and girls derive different benefits from parental engagement, possibly due to differing learning preferences or parental expectations. For every other parental factor, socioeconomic status, home learning environment, parental characteristics, and the combined effect, neither gender nor age reached significance, suggesting that the advantages of a supportive home and adequate resources are broadly consistent across demographic groups. Only involvement, the strongest lever of all, appears to work somewhat differently depending on whether the child is a boy or a girl, hinting that family-centered interventions may benefit from tailoring.

The authors are candid about limitations. Heterogeneity was substantial across analyses, with I-squared values exceeding 80 percent in most, indicating that contextual factors such as culture, measurement tools, and unmeasured moderators shape the underlying effects. The reviewed studies varied in methods, samples, and cultural settings, and some parental factor categories rested on few studies, so the findings should be read as indicative rather than definitive. The analysis also did not probe specific parenting styles, such as authoritative versus permissive approaches, and left moderators like teacher characteristics and school resources for future work. Culturally responsive interpretation remains essential, since involvement, home environments, and family-school relationships are expressed differently across societies.

Even so, the practical implications are difficult to ignore. The evidence supports prioritizing direct parental engagement in learning activities over policies focused solely on economic relief, though the authors note that accessible early childhood education and parental leave indirectly strengthen parent-child interaction. Home-visiting programs such as Parents as Teachers and Early Head Start, home-based literacy initiatives, parental training workshops, and frameworks like the Dual Capacity-Building Framework for Family-School Partnerships all align with what the data show works. For a generation of parents anxious about kindergarten readiness, the message is quietly empowering: the most powerful tool for preparing a child for school is not the bank account, but the daily, deliberate act of learning together.
