Abstract
The objective of the study is to develop or construct a Scientific Knowledge and Aptitude Test. 200 items were initially selected with 60 items from Life Science, 80 items from Physical Science and 60 items from Mathematics. A draft test was administered on 150 boys and girls of Class IX and 50 boys and girls of class X English Medium Secondary Schools of Kolkata. The major purpose of the study was to find out the difficulty value and discriminating power of the items by the method of item analysis, Where N = 150, boys and girls of Class Ix, difficulty value has ranged between .12666 to .79333 and discriminating power between .0118824 and .902439. The difficulty values were determined in terms of the samples passing an item and discriminating power was determined as per difference of such proportion between the top and bottom 27% of the sample groups. 100 items were selected for the final item pool and was administered on 99 boys and 127 grills (N=226 of the standardization sample. The range of Difficulty value and discriminating power of the final 100 item pool was 0.1681415 to 0.7654867 and 0.0044642 to 0.7951388 respectively. From the range of difficulty value and discriminating power of the final 100 items, it can be revealed that the items are spreaded equally on both the sides of .50 the items included was from the easiest to the most difficult the sampling was purposive.
