This case study of three female Chilean scientists with distinct levels of scientific writing expertise—novice, competent, and near-expert—investigates their notions about drafts. Interrogation of data—that is, document analyses, an entry questionnaire, a set of semistructured interviews, and member-checks—identified seven different notions about drafts: (1) draft as a canonical structure of scientific research articles, (2) draft as influenced by medium/time, (3) draft as an incomplete text, (4) draft as a process, (5) draft as product, (6) draft as a nondefinitive version, and (7) academic writing as a draft from scientific writing. Findings show that some shared notions about drafts transcend writer profiles and that these notions are rooted in writer identity, their writing practices, and the context of producing scientific research articles.
