 In 1995 they were fully integrated into the polytechnic subsystem (Administrative Rule 205/95 of 5 August 1995 - "Decreto Lei n.º 205/95, de 5 de Agosto"), and in 1999 the new courses in nursing were approved, conferring a "licenciatura" diploma (Administrative Rule 353/99 of 8 September 1999 - "Decreto Lei n.º 353/99, de 8 de Setembro").Between 1918 and 1974, some older schools that are today integrated into the polytechnic subsector were industrial and commercial schools of vocational education, as well as intermediate schools for primary-education-teacher training, schools of agriculture, or nursing schools.Current establishments for polytechnic studies in engineering such as the "Instituto Superior de Engenharia de Lisboa", "Instituto Superior de Engenharia do Porto", "Instituto Superior de Engenharia de Coimbra", the nursing schools, and the current polytechnic schools of education "(Escolas Superiores de Educação)" during that period had no relation with higher education, and were known by other names.
