SUNRISE Christian School's plans to establish a Year 8 level in 2013 have been shelved.
The school did not meet government regulations in regards to student numbers.
The government required 15 students to be nominated as continuing at the school, but Sunrise only had eight.
Campus principal Anne Dolan said she was "disappointed" at the situation. "Unfortunately it wasn't enough," she said.
The school is not making any futher decision on whether to re-apply to the government to expand their school in 2014.
"We're deferring a decision on whether to re-apply," Mrs Dolan said.
"It is a long process."
A parent, who did not wish to be named, hoped the school would be able to get numbers together and branch into the middle school. "I'm hoping that they re-apply. The same environment going between Year 7 and Year 8 was a positive thing."
The parent put their full support behind the school in any future plans, citing high teaching standards as the main reason.
For this year's Year 7 students still seeking Christian education elsewhere next year they will need to travel, either to Hamilton, Mount Gambier or further abroad. The others will go to Naracoorte High School.
Current Year 7 student Fletcher Tully said he'd been enrolled at St Martin's Lutheran College in Mount Gambier. He said he would have liked to stay in Naracoorte rather than travel long distances for his education.
"It would have been good," he said. "Instead of an hour bus ride the school would be right here."
