How important is the ISF score in Kindergarten?

A kindergarten teacher is concerned because the ISF scores of her kindergartners overall were very low. Children she sees as low achieving scored higher on ISF than children who are reading on Levels 2 and 3. Possible reasons for this? What is the reliability of the ISF scores for kindergarten?

I'm sorry it has taken me so long to get back to you regarding the reliability and validity of the ISF measure, but here it goes: The alternate form reliability for ISF ranges from .65 if you administer only one probe, to .90 if you administer 3 probes. The criterion-related validity ranges from .44 to .60 when compared with published norm-referenced tests such as the Woodcock-Johnson, SDRT, MAT, TOPA, IQ tests, etc. ISF is the weakest of the DIBELS measures in terms of reliability and validity, but still pretty strong, especially when looking at at least 3 data points over time. As for why lower-achieving students are scoring higher than higher-achieving students, I would look back to the raw data and see if the lower-achieving students are in a pattern of randomly picking a picture quickly rather than carefully selecting a picture, thus resulting in a slower time and lower score.
