What is meant by "omission" during a running record?

In the context of a running record, "omission" specifically refers to a situation where a reader leaves out or skips over a word while reading. This is significant in assessing a student’s reading fluency and comprehension, as it indicates that the reader may not be fully engaged with the text or may not have a complete understanding of the material. An omission can affect the meaning of the text, suggesting that the reader may need additional support or strategies to increase their accuracy and comprehension skills. This understanding helps educators identify areas where a student may require targeted intervention or instruction to improve their reading abilities.
