Parent involvement is often cited as an essential component of effective dual language bilingual education (DLBE), yet we have limited understanding of the ways parents participate in DLBE or how parent experiences differ between Latinx and non-Latinx families, who often have different reasons for enrolling their children in bilingual programs. Addressing these gaps, this article presents findings from a national survey of parent engagement and satisfaction for Latinx and non-Latinx parents whose children attend DLBE programs in Catholic schools. Findings revealed that parents viewed their involvement as important, although they reported being more involved in participation-oriented activities (e.g. volunteering in the classroom) than engagement-oriented activities (e.g. co-developing academic initiatives). Latinx parents reported similar or higher levels of involvement than non-Latinx parents in all areas except for school leadership. Parent satisfaction was extremely high, with Latinx parents expressing slightly higher satisfaction than non-Latinx parents. While parents were largely satisfied with school communication, many reported that certain communication was only available in English. These findings led researchers to conclude that high levels of reported satisfaction, particularly from Latinx parents, might obscure equity issues and that DLBE schools must look beyond satisfaction to understand parent experiences and to cultivate more equitable parent engagement.
