Abstract
The main objective of this research is to develop a standardized evaluation for Scientific Knowledge and Aptitude. A total of 100 items were given to 226 students (99 boys and 127 girls, N=226) from classes X, XI, and XII. The study employed Purposive Sampling. To determine reliability, the KR-21 formula was used, resulting in a reliability of .93614 for Life Science, .81553 for Physical Science, .85806 for Mathematics, and .88750 for the overall test. Validity was assessed through inter-item consistency using the inter-correlation method across all subgroups and subtests, with correlations ranging from .488 to .729, and the inter-correlation between subtests and the full test ranged from .773 to .940. For External Validity, the scores from the Madhyamik Examination (class X school leaving certificate examination conducted by the West Bengal Board of Secondary Education) in Life Science, Physical Science, and Mathematics were correlated with the standardized test scores, with correlations ranging from .266 to .663. The study suggests that more randomization is needed in the sampling process.
