Abstract: This study aimed at testing and validating Teacher’s Teaching Practices Questionnaire (TTPQ) of 24 items using Rasch measurement model. The instrument was used to identify teachers’ teaching preference. The 263 Mathematics secondary school teachers were selected to be the sample of this study. They were required to respond to a 5 point Likert scale of 2 constructs that include teacher centred teaching and student centred teaching. The analysis has shown that the person reliability is given by 0.71 and the separation index is 1.56. While the item reliability is at good level of 0.99 and the separation index is 8.29, the Rasch Model has given the empirical evidence that TTPI is valid and reliable according to psychometric characteristics.
