This study aimed to determine which types of context clues exist in children's texts and whether it is possible for experts to identify reliably those clues. Three experienced coders used Ames' clue set as a foundation for a system to classify context clues in children's text. Findings showed that the adjustments to Ames' system resulted in 15 clues that can be used to capture the majority of clues found in children narrative and expository text. This study adds to the limited empirically validated systems available for classifying different context clues. A usable classification of context clues has application to reading research that considers or controls for text factors as well as teaching reading strategies in K-12 classrooms.
