The International Secondary School Bridging Program is a preparatory English language and academic skills course designed specifically for international students from non-English speaking backgrounds who wish to enrol in an Australian secondary school. These programs focus on developing the four core macro-skill areas — reading, writing, speaking, and listening — within the context of secondary school subject content, enabling students to transition smoothly into mainstream Year 9 to Year 12 classes. Students are placed based on assessed English proficiency levels and progress through structured language units that mirror the curriculum demands they will encounter in their high school studies. In Australia, these programs are typically offered by specialist English language colleges, government school international student programs, and registered ELICOS (English Language Intensive Courses for Overseas Students) providers across all major cities.

The program suits international students aged roughly 13 to 17 who have received an offer of placement at an Australian secondary school but require additional English language and academic preparation before entering mainstream classes. Participants come from a wide range of countries, with particularly strong cohorts from Asia, the Middle East, South America, and Europe. Employers and stakeholders connected to this field include government education departments, private and independent schools, English language colleges, international student support organisations, homestay placement agencies, education agents, and state and territory registering authorities for international students. The broader international education sector in Australia is one of the country's largest export industries, meaning qualified professionals who work in and around these bridging programs are in sustained demand.

Most International Secondary School Bridging Programs in Australia require students to demonstrate a minimum level of English language proficiency before admission, though entry thresholds vary depending on the level of bridging program and the provider. Students enrolling in a junior high school bridging stream (targeting Years 7–10) typically need an IELTS score of at least 5.0 overall, while those preparing for senior high school (Years 11–12) are generally expected to achieve a minimum IELTS of 5.5 or an equivalent result in approved tests such as TOEFL iBT, AEAS, or Eiken. Where students fall below intermediate English level, they may first be placed in a General English class until they reach the proficiency level required for secondary school placement.

Academically, students are expected to have completed the equivalent level of schooling in their home country appropriate to the year level they are targeting in Australia. Providers typically conduct an initial assessment or placement test on arrival to determine the correct class level and identify specific learning needs. All international students must hold a valid student visa (Subclass 500) and provide a Confirmation of Enrolment (CoE) issued by their education provider. Additional requirements may include proof of age, certified school transcripts, parental consent documentation, and evidence of suitable accommodation arrangements such as homestay with an approved family or living with a parent or approved guardian. Some programs also require students to complete a pre-arrival health check and provide evidence of Overseas Student Health Cover (OSHC).
