This study examined associations between Latino parents' cultural orientation and their behaviors in support of their 9th grade adolescents in science (n= 104). Parents reported their orientation to mainstream U.S. and Latino culture, traditional cultural values, and immigration status. Adolescents reported how often their parents engaged with them in science related behaviors, such as general positive support in science, school involvement, teaching them things about science, discussing the future, and engaging in science-related co-activity. Results indicate that adolescent boys whose parents lack U.S. documentation are in greatest need of parent support in science.
