The Irish Second–Level Students' Union (ISSU)[3] is Ireland's national umbrella body for second-level students working through the student council network in second-level schools.[4] ISSU represents post-primary school students nationwide.[4]
ISSU's activities have three stated strands: it aims to provide training, guidance and advice to students and to equip them with the skills needed to become involved in the decision-making processes in their own school communities; and it aims to work with other organisations to bring the views of secondary school students to the attention of policy-makers and the media; and it aims to provide services to the membership of ISSU on the principle that control of those services lies with the membership.[5]
During September 2009, ISSU modified its name from the Irish Secondary Students' Union to the Irish Second–Level Students' Union to encompass all Irish post-primary schools.[9]
