Given the lack of research on measurement models used to operationalize parental involvement with secondary students, the goal of this research is to examine the measurement properties of the three-domain conceptualization of parental involvement including school-based involvement, home-based involvement, and academic socialization, compared to a more nuanced six domain conceptualization school-based (1) school/parent communication, (2) attending school activities, home-based (3) home activities, (4) homework help, academic socialization, (5) parent–child communication about education, and (6) parental aspirations for child's education. When comparing the fit among the models, the six-factor model had best fit indices and indicated varied correlations among the subdomains. The six-factor model allowed for more nuanced variations among the subdomains that may be helpful when assessing parental involvement with high school students.
