The cabinet was appointed by the Lieutenant Governor of Alberta on the advice of the Premier.

Members of the council are styled "the Honourable" only for the duration of their membership, not for life.

Klien's last cabinet was sworn in on November 24, 2004, following the 26th Alberta general election.

There was a cabinet shuffle on April 6, 2006, to fill vacancies caused by Lyle Oberg's dismissal and Ed Stelmach's resignation.

Members of the final Klein cabinet are listed in order of precedence.
