How we measure the level

Two things make text harder: longer sentences, and less familiar words. We measure both on every book and record what we found, then show you the number rather than a claim. If a draft misses the level it was written for, it gets rewritten before any pictures are drawn.

We store a grade estimate, a reading measure in the style of the ones schools use, and a banding letter. They are estimates. They are useful for matching a child to a book, and they are not a judgement about a child.

The order the sounds come in

For a child learning to decode, every word in a story has to be one they can sound out with what they have been taught, apart from a small set learned by sight and the character names. This is the order we follow.

  1. 1. First soundss · a · t · p · i · n

    Learned by sight: I, a, the, to

  2. 2. More single lettersm · d · g · o · c · k

Decodable text is a scaffold, not a reading programme. It comes off as a child moves on, which is why the restriction applies to one age band and not to the rest.
