Postsecondary students' well-being is closely linked to success, which has predominantly been viewed from institutional perspectives rather than student experience. Addressing this gap, students and educators at a New Zealand postsecondary institution identified elements of overall success. Two existing measures were integrated with the student/educator feedback to form a 27-item questionnaire that was piloted twice via social media using snowball recruitment (n=225, n=237). There was strong internal consistency, and factor analysis identified five main factors of influence. The survey is found to be a comprehensive measure of perceptions of success and could be useful in identifying learners' levels of success-promoting attitudes and strategies, which may be of particular relevance during the COVID-19 pandemic.
