As parent choice expands across states, families need clearer information about what schools actually teach—not just test scores, mission statements, or program descriptions. This article argues that curriculum transparency is essential for meaningful education choice, since parents often struggle to find basic details about the instructional materials, subject content, and learning approach used in local district, charter, or publicly funded private schools. By requiring schools to publicly list curricula by grade and subject, explain their instructional model, and include curriculum information on state report cards, states can help parents make more informed decisions about the education that best fits their children.
