"Over my decades in education, mainly in single-sex schools, I realised that something was missing for girls," principal Julie Peterson said.
"Our excellent academic programmes are not able to fully prepare them for the increasingly unpredictable world beyond their school years."
So, she created an advisory team of students and staff which conducted research to determine the 12 Shine Strengths and what the best way girls could learn about them.
The programme consists of workshops, six modules and masterclasses. Later in the year the team are also going to launch "Shine Field Studies" and "Shine Start Ups" which will allow the girls to use the strengths they have learnt.
Mentors meet with the girls in groups to share stories then smaller groups are formed to continue discussion.
Shine Programme manager Hannah Coltart said every woman they have talked to about the programme wants to be part of it.
"They understand how valuable these strengths are in finding personal satisfaction in life and are motivated to help girls gain this insight as early as possible.
"We have not even begun formal recruiting and we already have more than 50 women who have signed up."
Peterson is piloting the initiative at the school but plans to share the programme, materials and mentor infrastructure with other schools and organisations.
