Mela is the Hindi language word for fair, which is a traditional media to learn, earn, participate and share information. The paper describes perception scale development process and identification of different prospects of perception of the participants by administrating the tool on 60 randomly selected participants, during the three-day event of national dairy meals from 25th to 27th February 2015 at NDRI, Karnal. Final scale consisted of 20 statements (14 positive and 6 negatives) for which the t-values were found to be significant at one percent level of significance at 18 df and Cronbach’s alpha value of reliability was 0.851. Two other reliability tests were accomplished and Cochran's test of ANOVA was performed to test the signifi cance level of all 3 reliability test and it was signifi cant at 1 percent level (p<0.001). Content validity of the scale (S-CVI value) was 0.831. PCA extracted 4 prospects viz., ‘recognition prospect’, ‘learning prospect’, ‘get better prospect’, and ‘supportive prospect’. This methodological pathway viz., t-values cut-off for selection of statements based on the degree of freedom rule, reliability triangulation, Cochran's test for reliability signifi cance and extracting the latent constructs through PCA, can be followed by stakeholders for constructing different types of psychological scales. The attributes identified ed through PCA can be utilized in effective management and planning for organizing successful animal fairs.
