Does
peer factors do affect your academic performance? This is one of the most
important issues in social science. We use panel data of Taiwan Education
Panel Survey (TEPS), First-Difference model, and other statistical
analysis methods to avoid four statistical problems which may bias the
results. The result indicates that peers’ academic performance has a
positive effect on individual academic performance, especially for
high-performance students. We also find peers’ study climate would affect
individual academic performance negatively for students in tracking system
or whose academic performance in second quarterlies. Generally, we
conclude peer factors affect individual academic performance, but the
effects would difference according to individual academic performance, or
whether students is in tracking system.
