The successful candidates taking part in the Presiding Officer's, Dame Rosemary Butler AM, Women in Public Life Development Scheme will be introduced today (9 October).
Dame Rosemary will be joined by 15 mentors and 15 mentees, from across Wales, as she officially launches the scheme.
The aim to encourage more women to apply for public appointments and other roles in public life by providing mentoring, role-shadowing and training opportunities.
Equal opportunities charity Chwarae Teg and Cardiff Business School won the joint tender to run the project on the Assembly's behalf.
"I want to congratulate the 30 women who are taking part in my Women in Public Life Development scheme," said Dame Rosemary.
"I hope they are the pioneers behind which momentum will build and propel Wales towards becoming a society where women are truly represented on an equal footing in public life.
"We have 15 women who are already making their way in their chosen field, and 15 women who are ready to take the next step in reaching their full potential.
"My Women in Public Life campaign aims to ensure the effective development and progression of women into roles that often have a direct influence on people's lives across Wales."
The Presiding Officer will be joined by the mentors and mentees, representatives from Chwarae Teg and Cardiff Business School, and other guests at a launch event at the Senedd, on 9 October, at 12.30.
Joy Kent, Chief Executive of Chwarae Teg, the charity helping to create a Wales where women achieve and prosper, told us: "We are really pleased and proud to be working with the Presiding Officer, our partners and the mentors and mentees on such an important initiative.
"It is hugely important in these challenging financial times that women are represented in decision making in Wales and we believe the mentoring programme can make a real difference, not only to the numbers of women around the table but to what is discussed, how it is discussed and the decisions ultimately made."
