The information gathered while doing a running record is used to determine error, accuracy, and self-correction rates.
Directions for calculating these rates are given below. The calculated rates, along with qualitative information and the
student's comprehension of the text, are used to determine the student's reading level.
The qualitative analysis is based on observations that you make during the running record. It involves observing how
the student uses the meaning (M), structural (S), and visual (V) cues to help her/him read. It also involves paying attention
to fluency, intonation, and phrasing. Think back to the prompts you offered and how the student responded. These observations
help you form a picture of the student's reading development.
Error rate is expressed as a ratio and is calculated by using the following formula:
Total words / Total errors = Error rate
99 / 8 = 12.38, or 12 rounded to nearest whole number
The ratio is expressed as 1:12.
This means that for each error made, the student read approximately 12 words correctly.
Accuracy rate is expressed as a percentage. You can calculate the accuracy rate using the following formula:
(Total words read - Total errors) / Total words read x 100 = Accuracy rate
(99 - 8) / 99 x 100 = Accuracy rate
91/99 x 100 = Accuracy rate
.919 x 100 = 91.9%, or 92% rounded to the nearest whole number
You can use accuracy rate to determine whether the text read is easy enough for independent reading, appropriate to use without frustration during reading instruction, or too difficult for the reader. The breakdown of these three categories is as follows:

Self-correction rate is expressed as a ratio and is calculated by using the following formula:
(Number of errors + Number of self-corrections) / Number of self-corrections = Self-correction rate
(8 + 3) / 3 = Self-correction rate
11 / 3 = 3.666, or 4 rounded to the nearest whole number
The self-correction rate is expressed as 1:4. This means that the student corrects approximately 1 out of every 4 errors.
If a student is self-correcting at a rate of 1:4 or less, this indicates that he or she is self-monitoring his or her reading.
