What this is

Most curriculum data is either a flat list of standards or locked inside a product. This dataset is a connected graph of learning:

• 1,858 micro-topics — a single, teachable idea (e.g. “Building sentences”, “Apparent brightness of stars”), each with a plain-language description, mastery evidence criteria, a type (conceptual / procedural / representational / language / meta), a subject + domain, and an approximate age range.
• 3,994 prerequisite dependencies — a directed acyclic graph: “topic X depends on prerequisite Y”, each edge tagged hard/soft and carrying a one-line reason.
• Curriculum alignment — each micro-topic links to the standards it was distilled from (NGSS, Common Core, the UK National Curriculum, and more).
• Teaching research — 1,049 records. Coverage is partial; 809 topics have no research in this release.
• Domain clusters — 176 parent-friendly one-paragraph summaries per (subject, domain, age band).
