Explanatory Notes
* At the range mid-point, this is the probability students would correctly answer items measuring these concepts and skills. Both data from test items and review by NWEA curriculum specialists are used to place Learning Continuum statements into 
appropriate RIT ranges. Blank cells indicate data are limited or unavailable for this range or document version.
