Educators have relied on levels as a valuable tool to help them match students to texts they can read independently with fluency, accuracy, and comprehension. However, the truth is that leveling books and using levels as a tool to match students to texts isn’t as straightforward as we might hope (Glasswell and Ford 2010; Dzaldov and Peterson 2005; Sibberson and Szymusiak 2008).
We can evaluate books based on a variety of characteristics, but because qualitative leveling is done by humans and is, therefore, subjective, different people examining the same book may draw slightly different conclusions about what level is the best designation. We can use assessments to learn about what text a reader can read with accuracy, fluency, and comprehension—but based on a number of reader and text variables, what may be just right in one text on one day may differ from another text on another day.

A number of variables impact what students are able to comprehend from a text, and based on them, one individual child is likely to be able to read a range of levels and text types with independence. Start combining the variables and it soon becomes clear that matching readers and texts requires more than a single assessment to determine a level and instead requires a knowledgeable teacher who is in regular conversation with readers.
