The result of this research shows that there are two types of interlanguage fossilization that are commonly produced by students’ writing performance. They are syntactical fossilization and morphological fossilization. Syntactical fossilization consists of 71,86% and morphological fossilization consists of 28,14%.  Moreover, the interlanguage fossilization phenomenon in students’ writing performance is caused by the students’ low English proficiency. Therefore, students should be more active to improve their English ability.
