Data downloads
Every table on this site is downloadable as a CSV and every figure as an
SVG — free, CORS-enabled, CC BY 4.0.
Reuse them anywhere, including commercially; the only condition is a link
back to the page you took them from. All files are regenerated from the
13,258-assignment corpus on every build, so a file
you fetch is never staler than the page.

Figures (SVG)

- book-length-by-grade.svg Median assigned-book length for every grade — the 3rd-grade cliff.
