Based on the Personality-Job Fit Theory (PJFT), the mismatch of personality-job may cause over-qualification, and perceived over-qualification (POQ) may have a negative impact and affect career satisfaction (CS). This study conducted a questionnaire survey of 404 elementary school teachers in Fujian Province, China, and used the Two-way ANOVA and hierarchical multiple regression analysis to research primary school teachers’ POQ and the relationship between POQ and CS. The results of empirical research show that primary school teachers’ POQ is at the medium level. POQ of primary school teachers has a negative effect on CS, while professional self-identity (PSI) has the mediating effect on the relationship between POQ and CS. In addition, the study also found that new primary school teachers with high educational qualification have a relatively higher POQ, while older primary school teachers with low educational qualification have a relatively lower POQ.

根据人格-工作契合理论（PJFT），人格-工作不匹配可能会导致资格过高，而感知过的资格（POQ）可能会产生负面影响并影响职业满意度（CS）。本研究对福建省404名小学教师进行了问卷调查，并使用双向ANOVA和分层多元回归分析研究了小学教师的POQ以及POQ与CS之间的关系。实证研究结果表明，小学教师的POQ处于中等水平。小学教师的POQ对CS产生负面影响，而职业自我认同（PSI）对POQ与CS之间的关系具有中介作用。此外，
