Up to 2005 early childhood education in Zimbabwe was organised, directed and run by non-governmental organisations, churches and private individuals. Such an arrangement meant that the curriculum, personnel and strategies used to implement the programme were varied. In 2004 the Ministry of Education directed that all primary schools attach two classes of children aged between 3 and 5 years with effect from 2006, thus effectively making early childhood education part of the formal primary school structure. The research presented in this thesis focuses on teachers' perceptions of primary schools' state of readiness for the introduction of early childhood education in Zimbabwe. Located in the interpretive paradigm of qualitative research the study draws on a wide range of research methods. In particular a multiple case study was used to explore teachers' perceptions of primary schools' state of readiness for the introduction of grade zero/early childhood education in a former government group B school, a church run school, a rural school, a former government group A school and, a council run school. Some of the key findings of the study are: • School heads who are the principal gate keepers in primary schools were not provided with any preparation for the introduction of grade zero/early childhood education. • School reliance on fees and levies, without direct Ministry of Education financial assistance, meant that resource conditions - hence state of readiness - greatly differed from one school to another. • No ongoing support was provided to school heads, teachers-in-charge and early childhood education teachers. • The quality of teaching and learning at the early childhood education level, in the multiple case study, depended on the nature of teacher preparation, availability of appropriate resources, adequacy and appropriateness of teacher support, and teacher state of preparedness. The study recommends interventions that curriculum policy planners and implementers can use to create conditions that enable schools to be ready for installing, implementing and institutionalising the early childhood education innovation.
