Writing is one of the language skills that senior high school students in Indonesia seek to develop. One of the genres that students are required to learn is analytical exposition writing. However, present studies have found that students still frequently struggle to write this kind of text. The present study investigates the use of needs analysis to determine the needs of students in writing analytical exposition. The study was conducted with quantitative research which employed survey methodology. The instrument used was a questionnaire. The participants were 35 male and female eleventh grade students in one public school located in Bogor, West Java, Indonesia. The results showed that in terms of present situation analysis, students perceived studying writing as being very important. Moreover, the results from target situation analysis showed that students have the highest needs in using the present tense correctly, collecting evidence in research to gather data, elaborating ideas in pre-drafting, linking the sentences with conjunctions, and brainstorming, taking notes, and outlining ideas in pre-writing. In contrast, students considered publishing, revising and editing, as well as reflecting on the writing lessons, as moderately needed in the process of learning to write analytical exposition text.
