It was in 1974 that Alice Springs School of the Air became completely autonomous. Becoming the Correspondence School for Central Australia, all students’ families were given transceivers and the school its own frequencies. Correspondence work was now sent out to students, marked and returned from Alice Springs. The school now had enough students to have a teacher for each class. Patrols were made by class teachers to each of their students once a year. The first supervisors' conference is organised by Mr. David Ashton and is attended by 25 supervisors.
