We are exploring what secondary analysis of online anonymised PIAAC data can tell us about adults’ numeracy practices. In the process we review the accessibility and userfriendliness of the data for novice researchers and practitioners in the hope of encouraging them to explore this rich resource and give a brief account of our experience of the process of accessing publicly-available PIAAC data for secondary analysis.  \nKey words: assessment, numeracy, adults, mathematics  \nIn this paper we explore what secondary analysis of data from the latest international Survey of Adult Skills in the Programme for the International Assessment of Adult Skills (PIAAC 1), can tell us about adults’numeracy practices. In the process we are also reviewing the accessibility and user-friendliness of the dataset. We hope to encourage the exploration of this rich resource by practitioners and researchers, including those with little previous experience of working with large datasets. This is important because, as Hansen and Vignoles(2007, p. 1) point out “In the last few decades, there has been an unprecedented increase in the availability and quality of large-scale data sets that are suitable for use in education research. Analyses of these data have the potential to radically improve the robustness and generalisability of educational research”. In a still young but growing field such as adults learning mathematics, this is especially important.  \nWe focus on secondary analysis of anonymised publicly-available PIAAC data. We draw our understanding of secondary analysis from Dale, Watham and Higgins (2008, p. 520) :“Secondary analysis is generally understood as the analysis of data originally collected and analysed for another purpose”. In addition, Heaton (1998) says “Secondary analysis involves the use of existing data, collected for the purposes of a prior study, in order to pursue a research  \n1[http://www.oecd.org/site/piaac/surveyofadultskills.htm](http://www.oecd.org/site/piaac/surveyofadultskills.htm).  \nAdults Learning Mathematics – An International Journal 27  \ninterest which is distinct from that of the original work; this may be a new research question or an alternative perspective on the original question”. She adds that secondary analysis may be undertaken either by the original researchers or others.  \nThe OECD has published two analytical reports on PIAAC (OECD, 2013a, 2016a) . They relate to the first and second rounds of the PIAAC survey in participating countries. The New Zealand Ministries of Education, and Business, Innovation and Employment have published three initial reports: Ministry of Education & Ministry of Business, Innovation and Employment (2016a, 2016b, 2016c) . Secondary PIAAC analysis will tackle research questions and topics beyond what is covered in the initial reporting, or take different or more in-depth approaches.
