First Minister Rhodri Morgan is to face a two-hour grilling from senior AMs next month on care for older people.
Mr Morgan agreed to establish the Scrutiny Committee
The question-and-answer session is the first sitting of the new Scrutiny Committee, giving top AMs the chance to quiz the first minister every 16 weeks.
The committee, comprising the chairs of 10 committees, can name any policy area it wishes to discuss and can ask for further written evidence.
The Thursday 30 June session in Cardiff Bay is open to members of the public.
Mr Morgan agreed in February to establish the Scrutiny Committee.
It has the power to question the first minister on any matter for which ministers are responsible, other than Business Minister's responsibilities for business.
The subject of the first meeting will be 'Services for Older People'.
Committee Chair, Janet Davies AM, said: "I am delighted that this committee has been established with the agreement of the first minister, to allow members to question him in detail on issues that impact on the lives of people in Wales.
"It is an important step forward for the assembly, further enhancing the current process of parliamentary accountability of the Welsh Assembly Government."
The committee consists of the seven subject committee chairs and the chairs of the Audit Committee, the Committee on Equality of Opportunity and the Committee on European and External Affairs.
