The values and principles underpinning the "Leadership for Learning: Cambridge Network" support the distribution of leadership to all members of the school community. This paper introduces the HCD (Highest Common Denominator) Student Partnership as a key way in which the "Leadership for Learning" team learns from, explores and extends student leadership and participation within the current educational context. The paper opens with a consideration of current issues within the field of student voice before locating the contribution of the HCD Student Partnership within this field. Examples from recent projects with primary- and secondary-aged students are used to reflect on and illustrate the work of the Partnership with a view to sharing new practice and collaborating with new partners.
