BACKGROUND AND OBJECTIVES Despite longstanding efforts to design, implement, and study parenting interventions early in life to address disparities in school readiness, gaps remain related to understanding their long-term effects and pathways of influence on child development. Here we describe sustained impacts at child age 6 of the innovative, tiered birth to age 3 Smart Beginnings (SB) model. METHODS We performed a single-blind, 2-site randomized clinical trial of the SB model. SB integrates PlayReadVIP, a universal, pediatric primary care–based program, and Family Check-Up, a targeted secondary home-based parenting intervention. Mother-infant dyads (N = 403) were randomized at birth to standard pediatric care or the SB model. In line with SB’s theory of change that supporting parents will promote their children’s development, single and serial mediation pathways evaluated intervention effects of SB on age 6 child academic skills through parental cognitive stimulation at age 2 and child academic functioning at age 4. RESULTS We found significant single and serially mediated indirect effects of SB on academic outcomes through parental cognitive stimulation in toddlerhood and preacademic skills in preschool. The total indirect pathways were positive and statistically significant for all academic outcomes at age 6, including receptive vocabulary (effect size ES = 0.04, P = .04), oral comprehension (ES = 0.05, P = .04), letter-word recognition (ES = 0.04, P = .04), phonemic decoding (ES = 0.04, P = .04), and applied problems (ES = 0.05, P = .04). CONCLUSIONS Findings build on the demonstrated scalability of the SB model, support the cumulative process of academic functioning in childhood, and offer a promising model to address disparities early in life.
