What does the reading fluency prorating formula calculate?

The reading fluency prorating formula is designed to calculate a reading fluency score based on the number of words read correctly within a specified time frame. This score provides insight into a student's reading efficiency, which is a critical component of overall literacy development. By measuring fluency—how quickly and accurately a student can read—it allows educators to assess not just the speed of reading, but also the ability to process text smoothly and with expression.

This can be vital for identifying students who may struggle with reading as they may read more slowly or make more errors, which can impact their overall comprehension and enjoyment of reading. The other choices do not relate directly to the core purpose of assessing reading fluency; for example, measuring handwriting speed or tracking the number of books read does not assess the fluency of reading itself, nor does it evaluate comprehension directly, which involves deeper cognitive processes beyond merely reading the words.
