How We Rate
"HootRated helps parents find books that match their child's reading ability AND emotional readiness. We provide data. You make the decisions."
The Two-Axis Model
Every book on HootRated is rated on two independent axes. This is our core innovation — no other tool rates on both. For a data-backed walkthrough of why this matters — including a breakdown of every book in our catalog across the two-axis grid — see Reading Level Isn’t Enough.
Axis 1: Reading Level
How cognitively demanding is the text? Measured as a grade equivalent (K-12), drawn from established leveling measures and HootRated's own reading-level model.
Axis 2: Content Intensity
How emotionally/thematically intense is the content? Measured on a 1-5 scale from Gentle to Very Intense. Not a quality judgment.
Content Intensity Scale
Our 5-level scale is calibrated specifically for children's and young adult literature. Each level corresponds to a letter used in the HootRating code:
Gentle (Level 1)
No conflict beyond everyday childhood experiences. Themes: friendship, family, nature, learning.
Example: Frog and Toad, Goodnight Moon
Mild (Level 2)
Light conflict or tension. Mild peril, temporary sadness, gentle suspense. Characters face challenges but are never in serious danger.
Example: Charlotte's Web, Magic Tree House
Moderate (Level 3)
Real stakes and emotional weight. May include sustained danger, loss of a pet or family member, bullying, divorce, moderate violence in context.
Example: Harry Potter, Percy Jackson
Intense (Level 4)
Heavy themes explored in depth. Death of major characters, graphic war/violence depictions, abuse, discrimination, substance use, intense emotional distress.
Example: The Giver, Number the Stars
Very Intense (Level 5)
Graphic or sustained depictions of trauma. Sexual content, graphic violence, torture, self-harm. Typically YA crossover or shelved incorrectly in children's sections.
Example: The Hate U Give, Speak
The HootRating Code
Every rated book gets a short HootRating code that describes its content: how intense it is and what kind of content drives that intensity. The code says nothing about age or reading difficulty: the reading level and the age range have their own badges on every book page.
How to Read a HootRating
The First Letter
The content intensity, one letter per level of the scale above.
- C = Gentle (Level 1)
- L = Mild (Level 2)
- M = Moderate (Level 3)
- I = Intense (Level 4)
- V = Very Intense (Level 5)
The Second Letter
The primary dimension — what kind of content drives the rating.
- E = Emotional (grief, fear, trauma)
- P = Physical (violence, peril)
- S = Social (prejudice, substances)
- T = Thematic (dark/complex topics)
Gentle books (C) have no second letter.
Examples
The Dimension Breakdown
On every book page, you'll find a four-bar breakdown showing how each dimension scores independently: Emotional, Physical, Social, and Thematic. The primary dimension (the one that most defines the book's content) is highlighted with an arrow. This lets you see exactly what kind of content drives the rating — not just how intense it is.
This is especially useful for parents who know their child's sensitivities. A child who handles fantasy violence well but is sensitive to grief can use the breakdown to distinguish between a book rated MP (moderate physical — battles) versus ME (moderate emotional — loss).
Content Descriptors
Every book also gets tagged with specific themes present, using neutral, factual language. These are not judgments — they're descriptions to help you make informed decisions.
Examples include: Loss & Grief, Divorce & Family Change, Bullying, Mild Peril, Fantasy Violence, Identity & Self-Discovery, Romantic Content, War & Conflict.
How Ratings Are Built
Each rating combines several independent inputs, never a single opinion. The specific models and weightings are HootRated's own; what we publish is what each axis measures, the scale it uses, and how confident we are in a given book's rating.
| Rating element | Basis | Typical confidence |
|---|---|---|
| Reading level (measured) | Established leveling measures, where a publisher or leveling service provides one | High |
| Reading level (estimated) | HootRated's proprietary reading-level model, applied to the book's bibliographic profile | Medium |
| Content intensity | HootRated's rating process over the book's descriptive metadata, applied identically to every title | Medium |
| Content intensity (adjustment) | Independent, community-sourced content advisories, credited on each book page | High |
| Content descriptors and themes | Rating process plus community data and bibliographic metadata | Medium-High |
Confidence Badges
- High Confidence — Multiple data sources, community verification, full description
- Standard Confidence — Description + subjects available, some verification
- Preliminary — Limited data, clearly labeled for transparency
What We Are NOT
We are not a censorship tool.
- ✗ We never recommend removing books from any library or school.
- ✗ We never treat the existence of diverse characters as "content" to warn about.
- ✗ We never use words like "objectionable," "inappropriate," or "problematic."
- ✗ We never assign moral judgment to any content.
Intensity is not quality. A Level 5 book isn't a bad book. The Kite Runner is brilliant literature. It's also intensely graphic. Both things are true.
Representation is not a warning. A book having a transgender protagonist is tagged under "Identity & Self-Discovery" as a theme, not flagged as a concern.
Context matters. Our analysis considers the work as a whole, not cherry-picked passages. A book about the Holocaust will rate "Intense" for content, but our descriptors explain why — so you can decide if your child is ready for that important topic.
How We Compare
| Feature | HootRated | Common Sense Media | BookLooks |
|---|---|---|---|
| Reading Level | Yes (grade equivalent) | No | No |
| Content Rating | Yes (1-5 scale) | Yes (age-based) | Yes (0-5) |
| Specific Warnings | Yes (community-sourced) | Some | Some |
| Politically Neutral | Yes | Mostly | No |
| Transparent Methodology | Fully transparent | Partially | Opaque |
| Free Access | Yes | Yes | Was free |
The Reading Gap Score
Because we measure reading level and content intensity independently, we can also compute the Reading Gap Score — the distance between the two axes. It flags the books where the two pull apart:
- Sweet Spot (Score +3 to +5): Advanced reading with gentle content — for kids who read above their age but aren't ready for heavy themes
- Hi-Lo Books: High interest themes at accessible reading levels — for readers with dyslexia or processing differences
- Short + Complex: Rich themes in shorter formats — for readers with executive function challenges

Our Commitment
- Transparent methodology — this page exists so you can understand exactly how we work
- Open to feedback — we welcome correction and community input on every rating
- No political affiliation — we serve all parents, regardless of their beliefs
- Data over opinions — multiple sources, never a single reviewer's judgment
For librarians & educators
HootRated is free, needs no account, and shows every children's book's reading level and content intensity side by side, so families can find a book that fits a reader on both. It is a tool for choosing books, never for challenging or removing them (see What We Are NOT).
