Parafield Gardens High School has a growing international program. The school greatly values its cultural diversity, with staff and students from over 40 non English-speaking backgrounds, and many cultural events acknowledged and celebrated. International students are made to feel welcome and their Australian experience at PGHS is a truly multicultural one. With many local students studying EALD (English as an Additional Language or Dialect), international students are supported with English language learning in EALD classes from years 7-12. In addition, teachers from all subject areas have been trained to provide some EALD support.
The school enrolls students into several programs available for overseas students.
