Early reader books are for beginner readers who are developing their comprehension skills. Most children who read these books are from the age of three to six.  They are able to use the decoding skills they have learned without having to worry about an extensive plot.   Children with learning disabilities and attention disorders can also benefit from the simplicity and clarity of these books.

In addition, early reader books characterize situations that are familiar to the readers and which can help them improve their abilities to follow a sequence of events.  Lastly, the illustration of the text helps readers focus on the subject at hand.
