In this grounded theory qualitative study, we interviewed 34 graduates from one cohort of 51 students from a prestigious early college entrance program in China. Based on the interview data, we identified distinct convergent and divergent patterns of lived experiences and changes. We found several dominant themes, including peers' mutual stimulation for excellence, academic competition, big-fish-little-pond effect, coping with academic challenges, transition to college life, developing intrinsic interests, and making critical career decisions. Based on the thematic analysis, we developed a Cope-and-Grow model of strivings for academic excellence while developing one's self-identity. Three interrelated claims are made about the unique situation in which early college entrants found themselves, individual differences in coping and growing experiences, and intrapersonal changes over time. Rich connections are made between the Cope-and-Grow model and the extant empirical research and theories, such as aptitude theory, developmental asynchrony theory, and talent development theory. We also discussed the implications of the findings for curricular and instructional adaptation, counseling interventions, and future research.
