Parental trust and support are machineries for children's cognitive growth and behaviors exhibited at a later age. Their influence on students' learning engagement at school has been reported, but little is known about the mechanisms through which such a proposed causal effect occurs. This study tested 2 major proposed hypotheses; (1) general self-esteem (GSE) mediates the causal relationship between parents' trust and support (PTS) and Learning engagement (LE). (2) The mediation effect is further moderated by students' college grade level. Data was collected from 1139 college students in Tanzania (Mage = 22.5, SDage = 0.681) who filled out an online-designed questionnaire. SPSS (Statistical Package for Social Science), PROCESS macro of SPSS, and JASP (Jeffrey's Amazing Statistical Program) were used for analyzing data. The results indicated that GSE had a mediating effect (β = .0912, SE = 0.0134, P < .001) on the causal relationship between PTS and LE. The unmediated (direct) effect of PTS on LE (β = .2125, SE = 0.0419, P < .001) was lower than the total effect (β = .3037, SE = 0.0553, P < .001) after the mediation. The interaction effects of PTS (β = .0463, P < .001) and GSE (β = .0495, P < .001) on students' college grades were statistically significant, indicating that the mediation effect of GSE on the causal relationship between PTS and LE was moderated by college grades. Parental trust and support enhance students' behavioral learning at school through their general self-esteem, built from the family level (parenting).
