When assigning custom grade level for progress monitoring oral reading fluency, there should be a chart that explains when to move up or down in Lexile bands. I have students who are making progress on below grade level text (close to the 50th percentile) but I am unsure of when to move them up to the next Lexile range of text. When I do move them up, I have concerns about the new data (or until I figure out which level is best for progress monitoring), that all of the data points will be plotted on the grade. For reviewing data, it is nice to have progress monitoring for each Lexile range per page.
