Subject- verb agreement is very basic knowledge in making an English sentence. To produce a complete sentence, the students at least have to put one subject and one verb, and here is the importance of subject-verb agreement. This research aims at knowing the error types and calculating the production of subject-verb agreement error in students’ writing. However, the researcher limits the subject-verb agreement sentences on seven subjects, namely I, we, you, they, she, he, and it and later called as keywords. The data were collected from 99 essays from International Relations essay writing class batch 2016 at Language Training Center of Universitas Muhammadiyah Yogyakarta. In this research, the researcher used error analysis as design of this research, based on Corder (1967) in Agustina (2016) that was determining the data, identifying the errors, classifying the errors, explaining the error and quantifying the error.
