Rossmoyne Senior High has cemented its reputation as WA's flagship public school by having more students in the top one per cent of last year's TEE achievers than any other school in the State.
The Education Department said 27 Rossmoyne students - or 11 per cent of those who sat exams - achieved a tertiary entrance rank of 99 or above, earning them places in its exclusive "99 club".
They were among the top-ranked students out of more than12,000 from public and private schools who sat exams in four or more subjects last year.
The department said it was one of the best performances in the past few years. Rossmoyne had 21 students in the 99 club in 2008 and 25 in 2007.
Hale School, a private school which regularly produces some of WA's top performers, had 19 students, or 10 per cent, achieve 99 plus.
Rossmoyne can also boast two students who were among just 15 in the State to attain the highest possible rank of 99.95.
Ruwani Rajapaksa and Saksham Gupta said they did not believe it when they first saw their ranking.
"I screamed and ran around the house," Ruwani said.
The two students, who both hope to study medicine, took applicable maths, physics, chemistry and calculus. Ruwani also did English literature and French, while Saksham took English and human biology.
They were members of Rossmoyne's gifted and talented program and said their teachers had played a big part in their success.
Acting principal Terry Sanbrook said the school had expected to get about 20 students over the line, so 27 was a surprise.
He attributed Rossmoyne's success to its dedicated students and teachers who knew the courses.
"The whole ethos of the school is built around academic success and I think that culture is inculcated into the kids," he said.
