Prep in its current format was introduced into Queensland schools in 2007 as the government-run education year preceding Year 1.  At Yeronga State School in 2007, Prep began with a half-year intake of students. Purpose-built Prep rooms were placed down the eastern fence line of the Junior school so as to preserve the front oval and the unobstructed view of the heritage-listed brick ‘Infants’ building. By 2020 the school had 5 Prep classes on this site in these Prep buildings. Historically, Prep has already existed in Queensland schools. In the 1940s, there were 4 Prep modules each consisting of 6 months and taking a total of 2 years to complete. After Prep 1, 2, 3 and 4 were completed, pupils then proceeded to Grade 2. It is known that from 1952 onwards first schooling was in Grade 1 and any pre-school education was taken by the privately-run Kindergartens.
