After substantial literature review 60 items were selected covering all important aspects of fruit production. The prepared item was precisely examined and revised by a panel of experts in the fi eld of horticulture and extension education. Some items were reframed based of the suggestions made by the experts. The 58 items were considered for initial testing for developing a knowledge scale and were put down for item analysis. The prepared test was administered to 90 tribal farm women of Upper Subansiri district of Arunachal Pradesh for pre-testing through personal interview method from September- October 2021. Scores of one (1) and zero (0) were given for correct and incorrect responses respectively. For item analysis, item difficulty index and item discrimination index were calculated.
