The present study estimates the global validity of existing constructs and serves as the basis for the development of the "Self-Reported Study Habits for International Students (SR-SHI)" used to identify at-risk students in international programs. One-year classroom observations, recollection of study habits though interviews with high performing students show that they are mainly from low-context and individualistic countries while most low performing students come from high-context and collectivistic countries. Among other aspects, high performing students give opinions based on reading material and class content, use the expression "I think", ask questions in class, are on time, ask for feedback regarding assignments, take notes in class and while studying, look for the professor after class, sit at the front of the classroom and attend every class, study in silence and alone at regular times along the whole semester, read the material about two weeks before the exam, review notes before the exam, talk about the content with other students. On the other hand, low performing students remain quiet the whole semester, miss at least three classes per semester, are normally late, sit at the back of the classroom, don't take notes in class and never look for the professor after class hours. It seems that specific training programs at the start and during the semester as well as training on cultural intelligence were identified as necessary.
