The purpose of this study was to explore 11th- and 12th-grade students' expectations in the International Baccalaureate Diploma Program (IB DP) at a high school in the Western United States. Study participants included 92 of 94 high school students currently enrolled in the IB DP. Each participant completed a researcher-created, paper survey with 24 questions, using a 5-point Likert-type scale, as well as four demographic questions. Overall, students reported high expectations and beliefs for the program in helping them prepare for postsecondary education. Findings also suggested that females experienced more stress and feelings of being overwhelmed, while enrolled in the program as compared with males, despite a larger percentage of females reporting of postsecondary plans. In addition, Spanish-speaking students aspired to community college more than their peers, suggesting possible disparities in equity. A discussion of these findings and their implications are provided.
