We collected data on parental involvement from 101 American Indian parents in the Southeastern United States with children enrolled in kindergarten-12th grade. We analyzed the data using Pearson product-moment correlation coefficients and multiple regression modeling. Findings suggested that parental involvement is related to student achievement. Rational beliefs accounted for a significant amount of variance explained in authoritative parenting. School counselors familiar with the impact of parenting on student achievement are best positioned to support the success of American Indian students.
