The school was founded by the
Evangelical Lutheran Church of Hong Kong in April 1958 and initially borrowed 28B Grampian Road,
Kowloon City, to operate, adopting a half-day timetable. 2 years later, as the church that owned the address stopped renting it out to the school, they moved to a vacated campus at 23 Ho Man Tin Hill Road. In 1959, the school was approved to build a new campus at 52
Waterloo Road, which remains their address. They also opened a branch campus in Yuen Long, now
ELCHK Yuen Long Lutheran Secondary School. As the permanent campus was completed in 1964, the school officially moved into it. In its early days, the school had both Chinese and English classes and switched to using English as the sole
medium of instruction from 1981 to 1998. In recent years, the school has used both Chinese and English as mediums of instruction. ==Campus==
