Teachers usually teach according to how brains naturally learn. In this way, not only do their learners learn, retain, and recall quickly, but also the teaching becomes more joyful. Increased attention to the worthwhile role of the mind in learning/teaching in recent times Due to the lack of a valid scale for estimating teachers' awareness of brain-friendly teaching, the current study intended to construct and validate a 54-item brain-friendly teaching inventory by the implementation of the Rasch model. The test was administered to 200 Iranian EFL teachers from different educational contexts. The results revealed that all the 54 items of the scale had a good fit to the Rasch model. Infit and outfit values were within the acceptable range which indicates unidimensionality of the scale. Furthermore, it is asserted that the inventory enjoyed suitable reliability. This demonstrates that the Brain-Friendly Teaching Inventory is valid and can be applied as a scale for assessing the teachers' awareness of brain-friendly teaching.
