The Cornish Language Board was founded in 1967 by the joint resolution of the Gorsedd of Cornwall and the Federation of Old Cornwall Societies to continue the work of promoting Cornish which had been the responsibility of those two bodies. It is an elected Board with official representatives from Cornwall Council and the two founding organisations. Elections take place every three years, the electorate being the members of Kowethas an Yeth Kernewek (The Cornish Language Fellowship) world-wide,
The Language Board organises examinations each year, in May (oral) and June (written). There are four levels. For each of the grades one to three there are two parts – an oral examination and a written examination. For grade four there are three parts – oral, language and a literature/history paper.
