The present study examined whether students' perceptions of two major facets of parental and teacher academic involvement (i.e., academic support and academic monitoring), contribute to the process of students' achievement goals adoption. French junior high-school students completed two questionnaires assessing first their perceptions of parental and teacher academic involvement, and then their achievement goals three months later. Factorial analyses showed that students differentiated parental academic monitoring from parental academic support, while predominantly perceiving their teacher academic involvement as reflecting monitoring. Multilevel modeling analyses indicated that, as expected, students' perceptions of parental academic support were positively related to mastery goals while unrelated to performance goals. Also as expected, perceived academic monitoring was associated with performance goals, although the findings revealed an equal contribution of perceived parental and teacher involvement. This new insight about the antecedents of students' achievement goals emphasizes how important is the role of parental and teacher academic socialization.
