This paper reports on a major national study of higher education science and engineering learning communities in New Zealand. The scope of the research project along with a description of the methodology and method used in the study together with rationale for the study and research approach adopted are provided here. Details of the theoretical framework and a discussion of paradigm that underpinned the study are presented. A discussion of issues of reliability and validity and measures taken to maximize these also is presented. The paper begins with an overview of the New Zealand compulsory education sector and traces the now multitudinous pathways into higher education nationally. It thus provides a valuable context for this national study of higher education science and engineering learning communities.
