To figure out the percentile you can use a calculator like this:

the z-score = (standard score - mean standard score)/standard deviation. The standard deviation of the Naglieri is 15, and the mean standard score is 100, so z = (136-100)/15 = 2.4

Plugging that into the calculator on the website (you want to do the one-sided calculation) gives you 99th %ile.
