This research aims to identify the Public Relations (PR) measurement and reporting best practices for Arts and Culture-related CSR programmes in Southeast Asia. Interviews were conducted with senior PR consultants and in-house communicators to identify these practices. The author found, through in-depth interviews that (at the time the interviews were conducted), the PR practitioners and the organizations they represent, did not use any specific measurement and reporting methodologies for Arts and Culture related CSR programmes. The methodologies used to measure and report Arts and Culture-related CSR programmes were the same for other PR programmes. And despite the debate and criticism surrounding its use, the Advertising Value Equivalent remained the most popular measurement method.
