Education is conceived as a powerful agency for any national development. Development of a nation largely depends on the adequate availability of appropriately trained teachers and Trainee teachers of Teacher Education Institutions. Interest in teaching profession is a must to achieve the best aspect of development. Only, if there is interest towards teaching profession, a Trainee teacher can execute his/her varied teaching skill effectively from simulated environment to natural setting. An Inventory measures only selected aspects of personality contributing to the total behaviour of an individual. Teaching Interest Inventory attempts to provide a score indicating feelings of pleasantness-unpleasantness or like-dislike to varied teaching environmental stimuli, makes an important contribution to counseling thereby modifying the behaviour of trainee teachers and will more frequently cause the trainee teacher to investigate how she/he can develop his aptitudes in teaching.
