Guernsey's Education, Sports and Culture Committee will begin looking for a new member after Deputy Jayne Ozanne announced her decision to leave.
Deputy Jane Ozanne says she is stepping down from ESC for personal reasons.
Her successor is expected to be chosen later this month or in December.
She will remain Vice-President of Employment & Social Security, and a part of the Transport Licensing Authority.
"Sadly I feel that I must, for personal reasons, step down from the Committee for Education, Sport & Culture at the earliest opportunity.
"The last two months have been particularly difficult for me, and I now need to give time to sorting out matters to do with my late mother's estate and to grieve.
"It has been a real privilege and joy to work with my fellow ESC Committee members under the excellent leadership of Deputy Montague on what I see as one of our most critically important committees, which has a very broad and far-reaching mandate."
Committee President, Deputy Paul Montague, said Deputy Ozanne had been a valued Member of the Committee who would be missed.
"I was sorry to learn of Jayne’s decision because she has been a valued Member of our Committee and we will miss her contribution.
"However, I fully understand her reasons given her personal circumstances.
"I want to publicly thank Jayne for her efforts while on the Committee and wish her well.
"The Committee will shortly begin discussions with States Members about the vacant seat on the Committee before nominating a candidate for consideration by the Assembly."
