Suggested age, readers, English difficulty and US school grade are separate labels. Age groups are guidance based on source information or editorial review; unreviewed books are “Not assessed”. A US grade is assigned only with source information or a documented assessment; otherwise it is “Not assessed”. Levels use A1–C2 to indicate reading difficulty. StoryWeaver levels 1/2/3/4 use our approximate A1/A2/B1/B2 guide, labelled “estimated”; this is not an official equivalence. A book-specific assessment takes priority. Other unassessed books are labelled “Not assessed”. Source StoryWeaver levels are retained separately. Classics retain their original English.
