The results of the sample 9628743respondents' scores were subjected to item analysis, which included calculating the item difficulty index and the item discrimination index. The scale used for the final selection has 17 items with difficulty indices between 36.66 and60 and discrimination indices between 0.58 and 0.73. The reliability of the knowledge test under development was examined using the Split-Half method, and it was found to be 0.722.Aims: To construct a knowledge test to assess rubber growers’ knowledge onRubber Plantation Development and Extension Scheme.Study Design:Descriptive study.Place and Duration of Study:Karimganj, Assam, between January 2021 and December 2022.Methodology: A no. ofitems werecollected and 37 items were kept.
