This study explored global patterns and pathways in the award of the International Baccalaureate (IB) bilingual diploma (BD) and examined the relationship between several variables and the award of the BD. The sample comprised students from 139 countries, who earned the IB diploma between 2007 and 2012. The most common combination of languages studied in pursuit of the BD was English and Spanish. Results of logistic regression analysis revealed that a student’s native language is the strongest predictor of earning a BD. Non-native English speaking students are 17.7 times more likely than native English speaking students to earn a BD. Students from schools outside of the US are 3.5 times more likely to earn a BD than students from the US.
