Running Records

Running records are formative assessments undertaken in person with students as they read texts aloud. They are a swift and accurate method of checking reader progress as they are reading. Running records are the brainchild of Marie Clay, a developmental psychologist and one of the earliest literacy experts, who developed Reading Recovery.

Scoring a Running Record

You can score a child's reading performance for assessment in the following manner:

1. Do not count anything but the running words within a text. This means you don't count captions, subtitles, titles, etc.

2. Each of these should be counted as one error:

  • Substitutions
  • Permissions
  • Incorrect attempts
  • Unsuccessful appeals
  • Told words
  • Insertions

These should not be counted as errors:

  • Self-correction
  • Repetition
  • Accurate attempts
  • Successful appeals
  • Words that the child pronounces in a different way owing to their accent/dialect

3. If a child skips a line, count every word as one error.

4. If a child skips a whole page, count that as one error and take off that page's word count from the total.

5. If a child reads a proper noun incorrectly, only count mistakes as one error. With all other words, count all repeated mistakes as one error per mistake.

6. To produce a record, make a calculation of the Error Ratio that can then be reduced to the simplest expression.

We can calculate the Error Ratio with this formula:

Error Ratio = Errors ÷ Running Words

For meaning to be conveyed, the reader should have an Error Rate of 1:10 or less.

7. The Accuracy Percentage in a record can be calculated by subtracting all errors from the total of running words within the text, dividing the answer by the running word number and multiplying by a hundred:

(Running Words − Total Errors) ÷ Running Words ×100 = Accuracy %

8. Calculate the record's Self-Correction Rate. This Rate shows us the extent to which a child is monitoring his/her reading.

This rate can be calculated by adding together number of errors and number of self corrections, and dividing it by the number of self corrections:

(Total Errors + Total Self-Corrections) ÷ Total Self-Corrections = Self-Correction Rate

Self-Correction Rates of 1:5 or less indicate that a student is monitoring their reading and employing decoding is introduced.

9. Having made a calculation for accuracy percentage and self-correction rate, it is possible to assess whether for a specific student a book classified as being hard, instructional, or easy. These categories can be assessed thus:

  • Independent Level: Reasonably easy reading for the student (95 – 100% word accuracy)
  • Instructional Level: A challenge but one the reader can cope with (90 – 94% word accuracy)
  • Frustration Level: A problematic text for the student (less than 90% word accuracy)
