How to use this tool
A running record gives you more than a percentage. It helps you see how accurately a student is processing text, how often miscues occur, and whether the text is likely independent, instructional, or frustrating for that reader.
This calculator handles the routine math so you can focus on what the miscues actually mean instructionally. Use the output as a fast planning aid, then pair it with your observations about phrasing, decoding, and comprehension.
