Grinds

In Ireland, grinds are a form of private tuition. The grinds industry in Ireland, particularly at secondary school level, acts as a supplement to other forms of schooling and is described in some sources as "shadow education". In 2012, the Revenue Commissioners launched an investigation into a perceived failure of some teachers to declare extra income from giving grinds for tax purposes. The Association of Secondary Teachers, Ireland denied that this was a widespread problem.
