Complete the manuscript — story, structure, and age range confirmed
4–8 weeks (picture book); 8–16 weeks (middle grade chapter book)
Write the complete picture book or early reader manuscript. Children's picture books are typically 500–1,000 words (ages 3–7), early readers are 1,500–5,000 words (ages 5–8), and chapter books for middle grade are 20,000–50,000 words (ages 8–12). The age range determines the word count, vocabulary level, and page structure. A picture book manuscript is complete when every page turn is planned — picture books are not illustrated prose, they are a collaboration between words and images, and the page structure must be planned before illustration begins.
Proof required
Share your completed manuscript. State the target age range and word count. If this is a picture book, include a page-turn breakdown — note what happens on each page or spread. Write one sentence on what emotion or question you want a child reader to carry away from the book.
What gets checked
- Complete manuscript is shared — not an outline or a draft of the first few pages.
- Target age range and word count are stated and consistent with each other.
- For picture books: page-turn breakdown is included.

What a verifier looks for
- Word count and age range must be internally consistent — a 3,000-word picture book is structurally problematic for the format.
- For picture books: the page-turn breakdown is the most important structural element — ask whether each page turn creates a reason to turn the page.
- The emotional purpose of the book should be articulable — ask 'what do you want a 6-year-old to feel on the last page?'
Revise with feedback from at least one child reader and one adult reader
2–4 weeks (revision)
Revise the manuscript after receiving feedback from two real readers: at least one child in the target age range, and at least one adult (parent, teacher, or librarian). Children's books are unusual in that the buyer (adult) and the reader (child) are different people with different criteria: the adult needs to trust the content and want to read it aloud; the child needs to find it engaging, understandable, and emotionally resonant. Both feedback sources are necessary. The proof is the feedback itself and the revisions made in response to it.
Proof required
Share the feedback you received from: (1) one child in the target age range — what did they say, what questions did they ask, where did they lose interest if anywhere; (2) one adult reader — what did they think worked, what would they change. Share the revised manuscript and write one paragraph on the most significant change you made in response to feedback and why.
What gets checked
- Child reader feedback is shared — specifically noting where they engaged or lost interest, not just 'they liked it'.
- Adult reader feedback is shared — from a parent, teacher, or librarian, not just a friend.
- Most significant revision is described — the change and the reason for it.
Resources
What a verifier looks for
- Child feedback: ask how old the child was and what specifically they said — 'my nephew is 4 and he asked what happened to the dog at the end' is useful; 'kids loved it' is not.
- Adult feedback: ask whether the adult works with children in a professional capacity — a teacher or librarian will give more useful feedback than a parent alone.
- The most significant revision: ask whether the change was suggested by the child or the adult reader — this reveals where the most important feedback came from.
Submit to 5+ publishers or self-publish with public availability
4–12 weeks (self-publish); ongoing (traditional submission)
Either submit the manuscript to at least 5 publishers (or literary agents who represent children's books) or self-publish the book and make it publicly available for purchase. Traditional submission is a years-long process for most picture books — the evidence at M3 is the submissions themselves, not acceptances. Self-publication is a fully valid alternative that demonstrates the same craft commitment with a shorter feedback loop: a self-published book that is publicly available and has received at least one review from a reader outside the author's personal network is evidence of real publication.
Proof required
Share one of the following: (a) a submission tracker showing 5+ submissions to publishers or agents, with dates and submission materials; or (b) the link to the self-published book available for purchase (Amazon KDP, Ingram Spark, or equivalent) with at least one reader review from outside your personal network. Write one sentence on which path you chose and why.
What gets checked
- For traditional: 5+ submissions with dates and submission materials logged.
- For self-published: book is publicly available for purchase with a live URL and at least one external reader review.
- Which path and why — the reasoning demonstrates a deliberate publication strategy.

What a verifier looks for
- Traditional submissions: ask to see the submission tracker — each entry should have an agent/publisher name, submission date, and submission materials sent.
- Self-published: visit the book's URL directly and confirm it is publicly purchasable.
- External review: ask whether the reviewer is someone the author personally knows — a verified purchase review on Amazon from a stranger is more credible than a review from a family member.
