Simbi's Reading Levels : Emerging Readers, Grade 1 to 8
There are fluency passages for each grade level to benchmark reading levels. Our literacy experts carefully level each book according to Fountas & Pinell’s text descriptions, as well as Adrienne Gear’s Gear Levels.
We have a helpful Simbi Reading Levels Correlation Chart to help you switch from many other reading programs!
Simbi uses Words Correct per Minute (WCPM) scores to align with grade level standards.
What is a Words Correct Per Minute (WCPM) score?
A WCPM score is a ratio of correctly-read words to total-attempted words divided by the time taken to read the passage.
How does the scoring work?
Simbi uses industry standard oral reading rates, as determined by Hasbrouck and Tindal, to gauge readings on the Simbi platform.
Please refer to the chart below to gauge spoken words correct per minute against North American school grade levels.

Simbi's technology is always improving, but WCPM scored can be affected by self-corrections, background noise, and audio quality of recordings, Simbi recommends teachers use professional judgment in assessment of student reading.
