The indicators of parental involvement in children's education vary co
nsiderably across studies, most of which treat parental involvement as
a unidimensional construct. This study identified four dimensions of
parental involvement and assessed the relationship of each dimension w
ith parental background and academic achievement for a large represent
ative sample of U.S. middle school students. The findings provide litt
le support for the conjecture that parents with low socioeconomic stat
us are less involved in their children's schooling than are parents wi
th higher socioeconomic status. Furthermore, although schools varied s
omewhat in parental involvement associated with volunteering and atten
dance at meetings of parent-teacher organizations, they did not vary s
ubstantially in levels of involvement associated with home supervision
, discussion of school-related activities, or parent-teacher communica
tion. Yet the discussion of school-related activities at home had the
strongest relationship with academic achievement. Parents' participati
on at school had a moderate effect on reading achievement, but a negli
gible effect on mathematics achievement.
