This correlation chart aligns 4 reading assessment levels: Lexile, MAP Reading RIT, Fountas & Pinnell Guided Reading, and Accelerated Reader. I searched high and low for a correlation chart that aligned RIT's to Guided Reading levels. When I couldn't find one (for standard MAP, not Primary MAP), I created my own. MAP RIT's correlate to Lexile Levels, and Lexile levels correlate to Guided Reading Levels, etc. We use this chart to determine starting points for assessments (such as running records), as well as to diagnostically look at our assessment data reliability. Color coding on this one is random. The chart we use has an additional column with "AR Colors" and the levels align to those.
