This single table has become the most referenced reading benchmark in American education—and understanding it correctly can mean the difference between a student getting the help they need and falling through the cracks. The Hasbrouck-Tindal Oral Reading Fluency Norms, first published in 1992 and regularly updated, represent data from hundreds of thousands of students nationwide.

For background on what WCPM means and how it's calculated , see our complete guide. How the Hasbrouck-Tindal Norms Were Developed The Hasbrouck-Tindal norms are based on data from hundreds of thousands of students across the United States. Researchers collected WCPM scores from students in grades 1-8 during fall, winter, and spring assessment windows. This massive data set allows the norms to show what typical performance looks like at each grade level and time of year, broken down by percentiles.
