Are national percentiles available?
We do provide a technical report on our website with the system-wide percentiles from the 2001-2002 school year. Go to our Technical Reports page and download the following report: Good, R. H., Wallin, J. U., Simmons, D. C., Kame’enui, E. J., & Kaminski, R. A. (2002). System-wide Percentile Ranks for DIBELS Benchmark Assessment (Technical Report No. 9). Eugene, OR: University of Oregon. In developing the system-wide percentiles reported in Technical Report 9, we have limited information regarding the demographics of the students and schools. The data were generated based upon all of the students currently in the data system, so we cannot guarantee it matches your local situation nor to national demographics. Considering the very large sample of students (number of student per grade average over 20,000) in the sample, a reasonable interpretation would be that the sample is similar to most schools across the country. Further discussion on this is in the Technical Report. Do remember that
