This scale was developed using the Likert method, a technique for the measurement of attitudes (Likert, 1932). Likert items are useful and effective means of determining opinions and attitudes. Likert’s technique was preferred over Thurston’s technique because the former is easy to construct and less time-consuming. The instrument is categorized in several aspects of attitude toward Physical Science: (1) enjoyment, (2) confidence, (3) anxiety, (4) career, and (5) importance of science. PSAS is suitable to be used for both Upper Primary (Classes VI to VIII) and Secondary (Classes IX to X) school students across India and other Asian countries. It can be administered either individually or to a group.
