This study explores whakapapa as a tool, which can be used as a kaupapa Māori assessment framework in early childhood education, positioning kaupapa Māori theory as a paradigm base underpinning a philosophical and theoretical discourse towards assessment for children's learning. This thesis represents the culmination of a personal and professional journey, derived from the writer's longstanding interest in and commitment to kaupapa Māori early childhood education, and more specifically, philosophies and practices for assessment in this context. The study has canvassed a vast terrain of kaupapa Māori philosophy in its search for a theoretical grounding for a kaupapa Māori assessment framework for early childhood education. Foundation to the study has been the premise that the notion of whakapapa serves as an overarching philosophical matrix, encompassing the interconnected realms of genealogy, spirituality, and knowledge that precede, surround, and embrace the Māori child. Throughout the thesis, diagrams are employed to demonstrate and model the whakapapa underpinning the conceptualisations being explored. After contextualising the study within a historical overview of the impact of colonisation of kaupapa Māori education and research, it is suggested that a re-examination of key concepts from tikanga Māori will illuminate transformative possibilities applicable to the study's focus on the development of a theoretical base for an assessment tool within kaupapa Māori early childhood settings. Drawing from the literature, the thesis re-positions the view of the Māori child to one of being nurtured within a philosophical construct underpinned and immersed in tikanga such as whakapapa, ira tangata, whanaungatanga, mana and tapu, and ako, providing a strongly Māori theoretical base for the envisioning of the assessment process. The outcome of this study is to propose an assessment framework, which embodies and reflects these core kaupapa Māori philosophies as praxis.
