In modern software development, communication is one of the key success factors in software project development and team performance. However, software engineering (SE) students and educators may not have fully considered its significance in comparison to technical skills. The objective of the study was to determine the influence of communication self-efficacy and factors related to the theory of planned behavior (TPB) on the intention to pursue a career in software development. A survey was used to collect data from senior SE students at six universities in Thailand. The partial least squares-structural equation model (PLS-SEM) was used to analyze the data. The findings indicate that attitudes toward software development careers and communication self-efficacy for software development had a positive influence on the students' intention to pursue a career in software development. This study is the first attempt to investigate how communication self-efficacy in software development affects intention to work in a software development career. Educators can use the findings to improve curricula to foster students' communication self-efficacy and encourage them to pursue a software development career.
