In the present study, an effort is taken to translate the standardised Metacognitive Awareness Inventory of Schraw and Dennison to Odia language for the higher secondary school students of Odisha. By considering the implications of metacognition for higher secondary school students, this study was undertaken for cultural adaptation and validation. So far as the related literature available in Odisha about metacognition awareness inventory is concerned, the researchers did not find any instrument in Odia language, and as the higher secondary students in Odisha prefer both Odia and English language during instruction, and also realizing the need of a metacognitive awareness inventory in Odia language, this cross-cultural study was conducted. This study focused on examining the psychometric properties of the translated version of MAI and its validation. For the pilot study, 135 higher secondary school Odia medium students were selected randomly, and ten higher secondary school teachers were selected purposively to examine the test of comparability of language, the similarity of interpretation, and the degree of understandability of the translated MAI. Both forwards and backward translation of the MAI was done consulting both language and subject experts. The psychometric properties of the translated MAI were estimated. The KR-20 reliability and split-half reliability were 0.895 and 0.944, respectively, which revealed high internal consistency of the inventory. The opinion of the experts showed a high degree of comparability, similarity and understandability between English and Odia version of the inventory. The factor analysis by the principal component method with varimax rotation and Kiser normalisation extracted twelve principal components, and the implications of the study were discussed.
