In Malaysia, sixth form is a post-secondary education that is comparable to pre-university programs such as A-level and Foundation qualifications. Enrolment in sixth forms has dwindled over the past ten years due to assumptions that the curriculum is difficult and because it is offered in regular secondary schools. Thus, the sixth form transformation program was introduced in 2015 with the purpose to rebrand sixth form education to a new setting comparable to other pre-university education, with a focus on improving the school climate and increasing teacher self-efficacy. Therefore, this study was conducted to identify the level and relationship of the school climate on teacher self-efficacy. This survey was carried out using a questionnaire instrument, involving 695 sixth form teachers currently in Selangor. The findings showed that the level of school climate and teacher self-efficacy in all sixth form centers were at a high level. There was also a strong positive relationship between the school climate and sixth form teachers’ self-efficacy. Social and academic dimensions contributed significantly to the teacher self-efficacy of 38%. Hence, further studies looking at aspects that suggestively contribute to the school climate should be given due attention to ensure that transformation planning can be implemented as intended.
