This study aims to describe the pedagogical content knowledge (PCK) and teaching performance of junior secondary language teachers based on the tests administered during the teacher certification program, and identify the correlation between both variables. It involved 124 junior secondary school teachers, consisting of 70 Indonesian language teachers and 54 English language teachers, from various schools in West Java Province, Indonesia. To organize research procedures, this study adopted a descriptive method used to describe the characteristics of teachers who participated in the teacher participation program, their current pedagogical content knowledge and teaching performance based on the test results. Findings show that PCK has a strong correlation with teaching performance. However, other factors such as employment status, academic qualification, and age have significant effects on the mastery of those two main variables. A further study should be conducted to gauge more sound findings.
