Generational patterns in Mexican Americans' academic performance in an unwelcoming political context

•Immigrant students did less well in school at 5th grade but caught up by 7th grade.•Language hassles, English usage, and discrimination explained the early deficit.•Economic hardship mediated longer term academic performance.•Maternal educational expectations contributed to better immigrant achievement.

Research has shown that immigrant students often do better academically than their U.S.-born peers from the same ethnic group, but it is unclear whether this pattern holds for Mexican Americans. We examined the academic performance of four generations of Mexican American students from 5th to 10th grade looking for generation differences and explanations for them. Using data from 749 families, we tested a model with 5th-grade variables that differed by generation as potential mediators linking student generation to 10th-grade academic performance. Results showed that immigrants were academically behind at 5th grade but caught up by 7th. Only economic hardship mediated the long term relation between student generation and 10th-grade academic performance; maternal educational expectations and child language hassles, English usage, discrimination, and mainstream values helped explained the early academic deficit of immigrant children. The results identified potential targets for interventions to improve Mexican American students' academic performance.
