This is what our state documents say is required to get classified as LD”:
” A student who exhibits a discrepancy of 50 percent or more between expected achievement and actual achievement determined on an individual basis shall be deemed to have a learning disability”
Can someone give me an example of how to look at the 50%? Given an IQ of 120, say, what reading achievement score would be necessary? Thanks!
Re: IEP discrepancy question.
thanks! I looked everywhere for this information and just couldn’t find it. Appreciate it!
Karen,
If you look at the chart of standard scores and % tile in Pete Wright’s Test and Measurement document you will see how standard scores map to %tile. The document can be found at:
http://www.ldonline.org/ld_indepth/assessment/tests_measurements.html#anchor813501
The IQ of 120 maps to a %tile of 91. Take 91 - 50 which equals 41. So a child would have a descrepancy according to NY at 41 %tile. 41 %tile maps to > 87 standard score. My guess is the child would have to be below 87 to have the 50% descrepency. The federal law also states that you can’t just use one measure and that you have to look at other information; teacher observation, work samples.
