The objective of the survey was to examine the relationship between perceived teacher competencies in the era of Education 4.0 (TCEdu4.0) and teacher attitudes toward change (TATC) in Malaysian secondary schools. A total of 1,293 teachers from 80 secondary schools that were chosen using disproportionate stratified sampling method completed the questionnaires with valid data. The results demonstrated that, i) there was a significant, positive and strong correlation between TCEdu4.0 and TATC; and ii) except "Functional and Research Competency," "Self-Management and Interactive Competency," "Leading Learning and Mentoring," "Problem Solving, Technological and Digital Competency," and "Pedagogical Psychology and Assessment" were the five predictors of TATC that contributed 49.20% to the total variation. The study re-affirms the practicality of the competency and planned behavioural theories, provides evidence that teacher's individual factor is a major determinant of attitudes toward change. Moreover, it expands the understanding among educational practitioners regarding the interplay between these two variables and is a significant resource for Institut Aminuddin Baki in developing future training programmes for school leaders in enhancing TCEdu4.0 and TATC. In summary, the study offers valuable insights for driving school change effectively that sustainable school change is correlated to individual factors.
