The study was aimed to measure the strength and rationality of the compiled indigenous practices to explain their science and technology content. There existed high correlation and significant relationship between the perceived effect and scientific rationality of each ITK as perceived by ESS and RSS. Hence it could be concluded that majority of the ITK item with high perceived effect were perceived to have high scientific rationality also though a few showed no relation at all. This indicates that perceived effect of an ITK is highly influenced by its scientific rationality and vice versa.
