More high school students are seeking, and being offered, enrollment in accelerated curricula that prepare them for college and/or yield college credit than in previous decades. Two such accelerated curricula are Advanced Placement (AP) and International Baccalaureate (IB) classes and programs (Thomas, Marken, Gray, & Lewis, 2013). There is increasing diversity among students enrolled in AP/IB in terms of ethnic and linguistic backgrounds, socioeconomic status (SES), academic preparation, and prior experience managing rigorous academic coursework (Handwerk, Tognatta, Coley, Gitomer & ETS, 2008; McKillip & Mackey, 2013). In evaluating student success within these more diverse programs, researchers have raised questions of how success should be defined in terms of domains and indicators. Completion of accelerated courses was once considered the primary indicator of student success (Adelman, 2006), but performance on end-of-course exams has been argued by some as a more accurate indicator of student success (Ackerman, Kanfer, & Calderwood, 2013) than mere participation in AP or IB courses. An exclusive focus on academic skills and test performance may be too narrow, however. Students' quality of life and mental health outcomes are also relevant within a holistic definition of student success. The importance of considering such indicators of emotional well-being is due in part to the recognition that high school students in AP and IB classes report significantly higher levels of stress associated with intense curricular demands compared to students in general education (Suldo & Shaunessy-Dedrick, 2013b; Suldo, Shaunessy, Thalji, Michalowski, & Shaffer, 2009). Examining the emotional well-being of a population with greater stress is justified by research with general samples of youth that has established positive associations between stress and mental 758443G CQXXX10.
