Central Sydney Intensive English High School

Central Sydney Intensive English High School (CSIEHS), formerly known as Cleveland Street Intensive English High School, is an ESL high school located in the Inner Sydney suburb of Alexandria, New South Wales, Australia and operated by the New South Wales Department of Education. The school provides intensive English language, settlement, orientation and welfare programs to secondary aged, newly arrived permanent, temporary resident and international students. Settlement support and partnership programs are provided for the school's culturally and linguistically diverse parent community. The school's student and parent community come from more than 30 language backgrounds other than English. Bilingual staff support student learning and parent programs. The school's motto "Harmony and Progress" reflects the proactively inclusive education and welfare programs designed to enhance student resilience and achievement.

In 2018, the school moved into temporary buildings on the Park Street campus of the Alexandria Community School, to vacate the historic Cleveland Street Model School site on the corner of Cleveland and Chalmers streets, Redfern for a new, 14-storey inner city high school on that site, to be called Inner Sydney High School. The CSIEHS school relocated to its new, permanent campus on Mitchell Road early in 2019.
