Error Rate on Running Record is a literacy assessment tool that measures reading accuracy by calculating the percentage of errors made while reading a text passage. It helps educators evaluate a student's reading proficiency and identify areas needing improvement.
The calculator uses the Error Rate formula:
Where:
Explanation: The formula calculates what percentage of words were read incorrectly, providing a quantitative measure of reading accuracy.
Details: Calculating error rate helps educators assess reading fluency, identify specific reading difficulties, track progress over time, and determine appropriate reading levels for instructional materials.
Tips: Enter the number of reading errors and the total word count from the running record. Both values must be positive integers, with total words greater than zero.
Q1: What constitutes an "error" in running records?
A: Errors include mispronunciations, substitutions, omissions, insertions, and repetitions that change the meaning of the text.
Q2: What is considered a good error rate?
A: Generally, error rates below 5% indicate independent reading level, 5-10% instructional level, and above 10% frustration level.
Q3: How does error rate relate to reading accuracy?
A: Reading accuracy = 100% - Error Rate. For example, 95% accuracy means 5% error rate.
Q4: When should running records be administered?
A: Running records are typically used during guided reading sessions, reading assessments, and progress monitoring throughout the school year.
Q5: Are self-corrections counted as errors?
A: No, self-corrections are not counted as errors since the reader identified and corrected the mistake independently.
