Parafield Gardens High School has a growing international program. The school has great cultural diversity, with staff and students from over 40 Non English-speaking backgrounds international students are made to feel welcome, and generally fit in very quickly. Their Australian experience at PGHS can be a truly multicultural one. With many local students studying ESL (English as a Second Language), international students can undertake necessary English language learning in a mainstream class. In addition, teachers from all subject areas have been trained to provide some ESL support.
The school enrolls students into several programs available for overseas students.
