Alicia Blagg and Rhea Gayle progressed to Friday evening's women's 1metre final at the European Diving Championships in Eindhoven.
Blagg, 15, produced her international-best score of 255.65 to qualify in fifth just behind world-renowned names such as Tania Cagnotto and Anna Lindberg.
"I'm still not comfortable diving alongside these divers, I am kind of on a good day," said Blagg, who missed the final at the Euros two years ago.
"I'm just trying to get as much experience so to reach a final is great."
British champion Gayle, making her European debut, had to battle to go through in 11th with a score of 236.10.
"It's my first major international meet, I was nervous to begin with but I'm happy and excited to make it through," she said.
"I can improve on that (score) so hopefully I'll be calmer tonight and do my best."
Chris Mears and Nick Robinson-Baker will look to join them in the finals session when they compete in the men's 3m springboard synchro later on.
They won silver at the final World Series leg in Mexico last month, behind the all-conquering Chinese, to provide hope they could grab a second medal for Great Britain at this week's competition.
Women's 10m platform synchro team Tonia Couch and Sarah Barrow won gold on Thursday, ending Britain's 74-year wait for a female European diving title.
