Since 1984, the State, Regional and five Wildcard finalists who were in the running for National TV Winners were judged by the three major categories of Design, Performance, and Drama/Production - but there is a difference between the live events and the TV special. The judges adjudicating the performances judged them from a TV perspective. The first three schools that were worthy TV champions had themes ranging from an art like concept with attitude (1988 = Sarah Redfern High School; Culprits - NSW), tradition vs technology in Japan (1990 = St. Columba's College, Melbourne; Vivid Changes - VIC), and a biblical story of forgiveness (1991 = de la Salle College, Ashfield; The Prodigal Son - NSW).
