We have an ethical and a scientific imperative to do research that reflects the views and learning experiences of historically marginalized groups. Most studies that use a critical methodological approach rely on qualitative data. This article describes how a critical approach to recruitment, data collection, and retention can help to ensure that quantitative research accurately reflects the experiences of Latino immigrant families. The authors draw on relevant literature and their recent longitudinal study with 300 Latina mothers and their children from a rural community that focused on parent-child relationships and the development of math interest and achievement. The article includes recommendations to researchers about effective strategies for the meaningful engagement of Latino immigrant families in survey research studies. The strategies are situated within the context of existing discourses of recruitment and retention, as well as the theoretical and cultural considerations that are necessary for culturally competent quantitative research.
