Team Software Process is an integrated framework that guides development teams in producing highquality software-intensive systems. This paper analyzes the effects of TSPi training and the improvements achieved by 44 teams, comprising fourth-year students on the software engineering degree programme, corresponding to two academic years. This study shows the benefits of using defined models such as TSPi to improve the students' skills and knowledge. The metrics of size and effort estimation, defects, productivity and costs are collected to measure the improvements through two development cycles. © 2008 IEEE.
