As of now, this study includes only the four samples from the 2001 Student Guide for Arizona's Instrument to Measure Standards. Grade 8, November 1st in the KISS Grammar Workbooks includes scans of the original documents from the Arizona stnadards and material for using these passages for teaching. Four is a very limited number of samples, so I intend to find more samples and add them to this group. However, even with such a small sample, it is impossible to miss the wide range of ability among the students. 
     The material in the Workbooks includes the evaluations of these samples by the Arizona Department of Education.
