Parents' involvement in their children's education and parental warmth have been linked to many positive child outcomes. In addition to these positive associations, contemporary developmental theory stresses the interaction between different parenting variables and the interaction between parenting and broad contextual factors such as family socioeconomic status (SES). Thus, the purpose of this study was to examine main and interaction effects of parent home-based involvement and parental warmth on achievement outcomes. Additionally, we evaluated whether these variables also interacted with SES to predict students' achievement growth. Using the Early Childhood Longitudinal Study - Kindergarten Cohort of 2010-11 (N = 2352), growth of academic outcomes was modeled from kindergarten to the fourth grade. We then used latent variable interaction (Maslowsky, Jager, & Hemken, 2015) procedures to examine interaction effects of our primary study variables. Few significant effects were noted for children's reading and mathematics scores, but more substantial main (home-based involvement) and interaction (parental warmth and SES) effects emerged for science achievement. At high SES levels, warmth negatively predicted growth in science, whereas at lower SES levels, warmth positively predicted growth. Findings are discussed in relation to importance of parent involvement, differential effects across SES contexts, and curricular emphasis in contemporary schools.
