As the County Association of Local Councils (CALC) for the county of the Isle of Wight, IWALC provides representation, infrastructure and support to town and parish councils on the Isle of Wight. IWALC is a part of the national structure of the National Association of Local Councils (NALC), which provides centralised legal and other advisory services to parish and town councils. IWALC is also affiliated to the Local Government Association (LGA) which works with councils at all levels to support, promote and improve local government. Both of these organisations campaign and lobby direct to the National Government.
Representatives of IWALC are elected from its Executive Committee to serve on other bodies including the Isle of Wight Council's Scrutiny Committee, the IW Health and Well Being Board, Community Action Isle of Wight, The IW Area of Outstanding Natural Beauty and the South East Regional County Association Forum as well as to be the Island's delegates to NALC and the LGA.
One of IWALC's main tasks is to facilitate and finance the work of the County Association Training Partnership which provides training for local councillors. Recent courses have included Code of Conduct, Planning and Chairmanship skills.
