Five of the 23 students in 2013's year 6 class have been accepted into Smith's Hill High School, the only selective high school in the region.

Bridget McCormack, Grace Mahon, Tom Behl-Shanks, Aidan Hedges and Alex Swan all begin their first day of high school tomorrow, buoyed by the knowledge there will be several familiar faces in the playground.

To earn a place at the school, students sat a test early last year that assessed their ability in reading, writing, mathematics and general skills.

Tom, 12, said he was excited to expand his drama, sport and public speaking abilities at high school.

"It will definitely be a big change, I know everyone really well at Jamberoo and know it's going to be much bigger there," he said.

"I'm really excited about it and I can't quite wait."

Classmate Bridget, 12, said she was looking forward to more challenging mathematics.

"I was really excited when I found out and it's really hard to get in. I think it will be really fun and there will be a lot more opportunity there, but it's a bit scary because there's so many kids."

Justine Doorn-McCormack, Bridget's mum and a teacher at Jamberoo, said the students had all earned their place at the selective school.

"They've just been a group that have excelled in a lot of ways. They're a very highly motivated group."

A Department of Education spokesman said 13,102 of last year's 58,387 year 6 students applied for one of the 4188 vacant spots at selective high schools across NSW.

This means around 7 per cent of all NSW public primary school students were accepted into selective schools for 2014, an average Jamberoo Public School easily eclipsed.

School resumes for most students tomorrow.
