The research was carried out to estimate the psychometric properties of the social intelligence inventory (SII), developed by Lacanlale in 2013. Researchers adapted SII comprised of six subscales: Social Sensitivity, Social Communication, Social Influence, Social Efficacy, Social Catalyst, and Social Advancement. It encompassed of15 items in each subscale and three three-point Likert scale which was converted to 5 point Likert scale. The number of items was also reduced. After incorporating the changes suggested by the experts SII was administered to the 450 prospective teachers selected from the pool of population to run the CFA on the adapter version of the inventory. For the confirmation of the structure of the SII in the Pakistani scenario, Confirmatory Factor Analysis (CFA) was run. In the light of the results of factor loading against each item twelve items SS1, SS2, SS8, SC2, SC9, SI4, SI5, SI6, SE7, SE8, SE9, and SE10 were excluded as their loading value < .05. After deleting items with poor loading, 43 items were remained in the overall inventory. All items are uni-dimensional and have no negative items. CV of SII was assured by calculating AVE and CR after factor loading estimate. Both AVE and CR values of each factor lie in the accepted range. The internal consistency of SII was calculated with the help of Cronbach Alpha. Its value against each factor of SII as well as its overall value are in the range of accepted value (0.70 to 0.95).
