Parents of children attending a K-3 elementary school in New Mexico were surveyed by mail to examine Mexican-American and Anglo-American parental involvement in the school. Of 264 parents contacted, 24 Anglo-Americans, 19 Mexican-Americans, 1 African-American, and 6 individuals who did not identify their ethnic affiliation completed a questionnaire. Data were reported only for Mexican-American and Anglo-American parents. Results indicate that Anglo-American parents rated their children above average significantly more frequently than did Mexican-American parents. The most frequent type of involvement in the school, reported by both Anglo-American and Mexican-American respondents with annual incomes over $10,000, was attending conferences with teachers. The second most frequent activity for these parents was attending school-sponsored events. The most popular activity for Mexican-American parents whose annual income was below $10,000 was participation in fund raising projects for the school. The most frequent types of involvement for Anglo-American parents with annual incomes below $10,000 were attending parent-teacher conferences and attending school-sponsored functions. The reasons for involvement differ between the two groups: Mexican-Americans get involved because their children wanted them to do so; whereas Anglo-Americans get involved because they "want to help." This study suggests that school personnel should encourage parental involvement since it is associated with improved student achievement. (LP)
