THE QUESTION
What changes between writing scores—and what can we teach from that difference?
What you can explore
- Explore patterns across grades 3–8, English I, and English II.
- Compare selected anchor essays side by side.
- Toggle writing-structure highlights and explore focused teaching moves.
A deliberate choice
Keep actual writing close to the analysis. Pair patterns with annotated responses so a teacher can inspect the evidence instead of taking a summary on trust.
What it is built on
The published analysis covers 1,419 state-scored responses, with 49 selected anchors. Official scores remain the reference point; anonymized student writing is presented verbatim for calibration.
KEEP IN VIEW
What this can’t tell you
Writing-move signals and highlights are instructional aids, not official rubric scores or automatic grading. Cross-grade responses use different prompts, and small score bands are noisier.
