Methodology

Every book in the dataset is cross-referenced against at least one primary source: the Common Core State Standards Appendix B exemplar list (achievethecore.org), an AP / IB / Cambridge syllabus or course audit, a published state ELA framework, or a public-facing district curriculum page. Each assignment row stores the source URL alongside the book × curriculum × grade × state metadata, so any reader can audit the underlying citation. Reading-level data (Lexile measures, grade ranges) is sourced from MetaMetrics, Open Library, and publisher metadata; banned / challenged status from PEN America’s Index of School Book Bans and the ALA most-challenged list.

For full per-record citation framework, see the ReadingList Classification Standard. The full dataset is browsable across the state, grade, and curriculum hubs, each citing its source (CC BY 4.0).

Finding 1 — The Common Core canon dominates

The top 20most-assigned books in the dataset account for a disproportionate share of citations, confirming what English department chairs have known for decades: the “canon” — a stable set of mid-20th- century American novels — anchors most US high-school ELA curricula. The top entries below appear in Common Core Appendix B, AP English Literature course audits, IB Diploma Programme prescribed lists, and state ELA frameworks simultaneously.

  1. Wonder — R.J. Palacio · Lexile 790L
  2. New Kid — Jerry Craft
  3. Shiloh — Phyllis Reynolds Naylor · Lexile 890L
  4. Out of My Mind — Sharon M. Draper · Lexile 700L
  5. The Crossover — Kwame Alexander · Lexile 750L
  6. Holes — Louis Sachar · Lexile 660L
  7. Escape from Mr. Lemoncello's Library — Chris Grabenstein
  8. The War That Saved My Life — Kimberly Brubaker Bradley · Lexile 580L
  9. Restart — Gordon Korman · Lexile 730L
  10. Smile — Raina Telgemeier · Lexile 410L

Finding 2 — Curriculum coverage is uneven

Of the 67 curriculum frameworks tracked, coverage by book count varies sharply. Common Core State Standards (which 41 states have adopted in some form) leads; AP English Literature and IB Diploma Programme English follow closely. State-specific frameworks (Texas TEKS, Florida B.E.S.T., NY Next Gen) typically overlap heavily with Common Core exemplars but add region-specific titles.

Finding 3 — Banned-book pressure clusters on canon titles

42titles in the dataset have documented removals, restrictions, or formal challenges in at least one US school district per PEN America’s 2022-2024 index. The most-banned titles overlap substantially with the most- assigned canon — books like The Bluest Eye, Beloved, and To Kill a Mockingbird appear simultaneously in Common Core exemplar lists AND on multi-state challenge indexes, suggesting challenges target widely-taught texts rather than fringe selections.

  1. The Bluest Eye — Toni Morrison · documented in 16 states
  2. The Kite Runner — Khaled Hosseini · documented in 12 states
  3. Slaughterhouse-Five — Kurt Vonnegut · documented in 12 states
  4. The Perks of Being a Wallflower — Stephen Chbosky · documented in 11 states
  5. The Hate U Give — Angie Thomas · documented in 10 states
  6. Beloved — Toni Morrison · documented in 8 states
  7. To Kill a Mockingbird — Harper Lee · documented in 8 states
  8. The Absolutely True Diary of a Part-Time Indian — Sherman Alexie · documented in 8 states
  9. I Know Why the Caged Bird Sings — Maya Angelou · documented in 7 states
  10. The Handmaid's Tale — Margaret Atwood · documented in 7 states

See the full per-state breakdown at /banned-books. “Documented in N states” means at least one district within each listed state has formally challenged or removed the title; no state has a universal ban.

Finding 4 — Lexile measures by grade band

Reading-level expectations rise non-linearly through K-12. The K-2 band concentrates around 200-600L (decoding-heavy picture books and early chapter books). Grades 3-5 widen to 500-900L as narrative complexity grows. Middle grades (6-8) mostly fall in the 700-1100L range. By high school (9-12), assigned texts cluster between 900-1300L, with AP/IB texts reaching 1400L+ for dense classics.

  • Grades K-227 books · 210–990L · mean 545L
  • Grades 3-581 books · 360–1020L · mean 758L
  • Grades 6-832 books · 530–1300L · mean 852L
  • Grades 9-1241 books · 590–1420L · mean 933L

Finding 5 — State-level citation density

Citation counts vary by how publicly accessible each state’s ELA framework is. States with publicly indexed, named ELA standards (Texas TEKS, Florida B.E.S.T., Massachusetts ELA Frameworks, New York Next Generation) appear with the most distinct citations because their reading lists are straightforwardly indexable.

Finding 6 — Citations cluster in upper grades

Assignment density rises sharply through middle and high school. Elementary grades (K-5) typically rely on teacher- level title selection rather than formally cited reading lists, while AP / IB / Cambridge frameworks pin specific titles to specific course years in grades 9-12 — producing denser citation records there.

How to use this data

  • Parents + teachers: see grade-level reading lists or state-level reading lists to find exactly what’s assigned in your school context, with cited sources on every book page.
  • Librarians + curriculum coordinators: the curriculum hub shows the Common Core / AP / IB / Cambridge crossover for collection-development decisions.
  • Researchers + journalists: the full dataset is browsable across the state, grade, and curriculum hubs, each citing its source. CC BY 4.0 license; please credit ReadingList.school in published work.
  • Bloggers + educators: the embeddable widgets let you drop a grade / state / curriculum reading list into any site (no JS framework required, CC BY 4.0).
