Eric_Florida Posted June 7, 2016 Posted June 7, 2016 I'm trying to understand some results for an ITBS Level 16 test. This was a Grade 10 test taken in 1992. I'm hoping to use this as a baseline to hopefully correlate to a panel of testing recently to evaluate potential Traumatic Brain Injury. Any help is greatly appreciated. Thank you in advance! Reading Comp: GE - 140, NCE - 68, SS - 201, NPR - 81 Math: GE - 155, NCE - 77, SS - 205, NPR - 90 Writing: GE - 139, NCE - 70, SS - 204, NPR - 83 Using Sources: GE - 175, NCE - 83, SS - 227, NPR - 94 Basic Composite: GE - 156, NCE - 77, SS - 209, NPR - 90 Applied Proficiency: RS - 49 Quote
73349 Posted June 7, 2016 Posted June 7, 2016 (edited) The most helpful thing in that list is NPR - National Percentile Rank. That means, out of 100 typical test-takers that year, how many did this person do better than? This test-taker did above average: Reading Comprehension: 81st percentile = better than 81 out of 100, good Math: 90th percentile, top 10% Writing: 83rd percentile, better than 4 out of 5, good Using Sources: 94th percentile, very good Basic Composite: 90th percentile, top 10% overall, looking at the various tests together. Applied Proficiency: RS - 49 - I don't know what this one means, sorry. Edited May 31 by 73349 Quote
EKS Posted June 7, 2016 Posted June 7, 2016 (edited) In addition to what whitehawk said, since, in general, achievement test results are very well correlated with intelligence test scores, these percentile rank scores could be used as a reasonable proxy for IQ if no actual IQ score exists.

Eric_Florida Posted June 10, 2016 Author Posted June 10, 2016 Thanks whitehawk and EKS. That is good info. The percentile I was familiar with. I have had MANY head traumas/concussions, but growing up in the late 80's/early 90's, it seems the adults thought if you were playing football in the street and your head bounced off the asphalt, that you had a hard head. :( Quote
