After much preparatory work, the Catholic Education Office in Western Australia determined to move Year 7 students from its more than 100 primary schools to secondary schools in 2009. This was the first time in the state's history that a major education system had embarked on such an undertaking. This system-wide shift presented a unique opportunity for investigating the degree of success experienced when viewed through the eyes of relevant stakeholders. This paper reports second phase results (stakeholder perceptions) of a prior study that reported details of the preparation undertaken in anticipation of the move. Issues identified here have clear implications for other systems that may be contemplating the creation of a six plus six primary-secondary schooling structure.
