The computer based Microsoft excel spreadsheet (2007) was prepared to document the obtained score and the same used for statistical analysis. Through recent method of item analysis, Cronbach’s Alpha values were computed using IBM SPSS software. The reliability coefficients were found 0.874(Spearman-Brown) and 0.672(Guttmann Split-Half). Hence, the present pilot study revealed that the scientific aptitude test for secondary students to ignite their scientific temper and also useful in preparing future competitive examinations.
