Understanding Running Record Accuracy Rate
A running record is a vital tool for educators to assess a student's reading proficiency. It involves a student reading a passage aloud while the teacher or observer notes specific behaviors, including word recognition, miscues, and self-corrections. A key metric derived from a running record is the accuracy rate, which quantifies how accurately a student is reading the text.
What is Accuracy Rate?
The accuracy rate tells you the percentage of words a student read correctly in a given passage. It is calculated by comparing the number of words read correctly to the total number of words in the passage. A high accuracy rate generally indicates that the text is at an appropriate difficulty level for the student, allowing them to focus on comprehension. A low accuracy rate might suggest the text is too difficult.
How to Calculate Accuracy Rate
The formula for calculating the accuracy rate is straightforward:
Accuracy Rate = ((Total Words Read – Number of Errors) / Total Words Read) * 100
In this formula:
- Total Words Read: This is the total number of words in the passage the student attempted to read.
- Number of Errors: This includes any misread words, omissions, or substitutions that were not self-corrected.
A commonly accepted benchmark for independent reading is an accuracy rate of 90-95%. For instructional level reading, 95-99% accuracy is often targeted.
Example Calculation:
Let's say a student reads a passage with 100 words and makes 5 errors (misreads, omissions, etc.).
- Total Words Read = 100
- Number of Errors = 5
Using the formula:
Accuracy Rate = ((100 – 5) / 100) * 100
Accuracy Rate = (95 / 100) * 100
Accuracy Rate = 0.95 * 100
Accuracy Rate = 95%
This means the student read the passage with 95% accuracy, which typically falls within the instructional or independent reading range, indicating the text is likely at an appropriate level of challenge for them.
