This research examined the range of reading fluency and comprehension scores of 1,149 students in five diverse elementary schools, including a gifted and talented magnet school. Results revealed a range in reading comprehension across all schools of 9.2 grade levels in Grade 3, 11.3 in Grade 4, and 11.6 in Grade 5. A similar wide range of oral reading fluency scores was found across all elementary schools, as students scored from below the 10th percentile to above the 90th percentile. These results demonstrate the wide range of reading achievement in diverse populations of students, including gifted students, and the need for teachers to differentiate both reading content and instruction to enable all students to make continuous progress in reading.
