The Centre for Rehabilitation of Hearing and Speech in Ljubljana has been established in 1900. Its meaning is pretty considerable as the former two institutes (in Gorizia and Šmihel) hat not accepted the children of both sexes of the previous Carniola country as the Centre began to practise. At the time of the establishment of the Centre also the first Slovene teachers for the deaf had been qualified, who (especially the headmaster Fran Grm) in the first half of the 20th century raised the professional level of the institute — not only on the Yugoslav, but also on the European level. At the same time the Charitable Society for the Deaf Young (in 1930) and the first organization of the deaf for the Drave banovina (in 1931) have been established — mostly thanks to the hard work of the institutional teachers. After the liberation (in 1946) the Professional school for the deaf young, the first of this kind in Slovenia, has been established, and in 1948 the so called Apprenticeship Workshops, which are of extraordinary meaning for the professional rehabilitation of the deaf young. The collaborators of the Centre of Ljubljana also gave the iniciative to establish the Institute for correction of hearing and speech in Portorož (in 1946) the Centre for correction of hearing and speech in Maribor (in 1963), as well as the new building for the Centre in Ljubljana (in 1963).
