Heathdale Christian College will offer classes up to grade six at its Melton campus next year.
The school, which celebrated its first anniversary last week, operates out of the former Mowbray College site.
In its first year it offered classes from prep through to grade four and is keen to continue toward its goal of offering a kinder to year 12 curriculum by 2021.
Heathdale Christian College enrolment officer Annisa Croxon said the school was “serious about growing”.
“I think the Mowbray experience has hurt the local community and there is a suspicion about whether we are serious or able to do all we plan,” she said.
“I hope that the community will notice we are there. We are doubling [student] numbers next year and we are serious about seeing it grow.”
The school hopes to keep up with the fast pace of growth of the western suburbs and start classes for year seven students by 2017.
“The usual problem with fast growth corridors is that infrastructure rarely keeps pace,” Ms Croxon said.
“We feel we are well placed to help the community in at least one of those infrastructure tight spots.”
There were 33 pupils at Heathdale Christian College this year.
