There was no scale available to measure attitude of people about agricultural biotechnology. The present study was undertaken to develop the same during 2016–17. The method of summated rating suggested by Likert (1932) was followed in the development of scale. Fifty statements about agricultural biotechnology were collected. These statements were edited and framed in such a way that they expressed positive or negative attitude. These statements were provided to thirty judges for ensuring relevancy of statements. Based on the jury opinion, 32 statements were found relevant. Item analysis of these 32 statements was done. The ‘t’ value of all 32 statements and mean ‘t’ value were calculated. Statements having higher ‘t’ value than mean t values were selected. In this way, a total of 18 statements (having 8 positive and 10 negative statements) were selected for final attitude scale. This scale was found reliable and valid. It can be used for measuring attitude of people about agricultural biotechnology.
