The introduction of the community school model in the 1970s controversially removed the denominational basis of the schools, but religious interests were invited to be represented on the Boards of Management. Community schools are divided into two models, the community school vested in the Minister for Education and the community college vested in the local Education and Training Board. Community colleges tended to be amalgamations of unviable local schools under the umbrella of a new community school model, but community schools have tended to be entirely new foundations.

What didn't the community school system remove from the comprehensive school model?
