The responsible speech therapist must have practiced at an institution designated by the central competent authority for at least two years. The years of practice mentioned in the preceding paragraph are recognized only if the responsible speech therapist has a speech therapist certificate and has registered his or her practice with the municipality or county (city) authority according to law. Notwithstanding the foregoing, the actual years of service rendered by a practicing speech therapist before this Act is promulgated are also recognized.
