Holy Trinity Lutheran College has proudly served Horsham and the surrounding local communities with quality independent education since 1978. Located in the heart of the Wimmera, in western Victoria, the college was established by the Holy Trinity Lutheran Church as a co-educational, independent Christian school. At the time it was known as Horsham Lutheran Primary School. It began with 58 students and 3 teachers and lessons were conducted from the church hall.
Holy Trinity Lutheran Church purchased land and built a primary school facility on the current school site, opening in 1979. The school community continued to flourish during its early years and the school expanded to double stream for all classes in Foundation to Year 6. In 2008 the school changed its name to Holy Trinity Lutheran School to further strengthen its connection with the local Lutheran church.
Middle schooling was introduced in 2014 and from 2017 educational programs through to the senior years of education were delivered with the aim of providing a leading educational pathway for all students from Foundation to Year 12. To reinforce its identity as a Foundation to Year 12 educational facility, the school rebranded to Holy Trinity Lutheran College in the second half of 2017.
Building of the Senior School commenced in 2018, with the precinct operational in Term 2 of 2019. The final stage of the Senior Centre was completed in 2021, completing the college's transition into offering Senior schooling.
The college’s history has been one of rich tradition and it continues to honour the strong foundations that have been established in the past, while creating a contemporary and vibrant school environment for the future.
