Where can I get information about the difficulty level of the ORF passages?
The reading passages within a grade are all of approximately equivalent difficulty. For a detailed summary of the readability levels for the 1st-3rd grade reading passages, go to our Technical Reports page and download the following report: Good, R. H. & Kaminski, R. A. (2002). DIBELS Oral Reading Fluency Passages for First through Third Grades (Technical Report No. 10). Eugene, OR: University of Oregon. We have not received information on the difficulty levels of the 4th-6th grade passages yet.
