This paper reports on progress to date with a project underway in New Zealand involving the extraction of data from multiple government agencies that is then combined into one comprehensive longitudinal integrated dataset and made available to trial participants in a way never previously thought possible. The dataset includes school leaver achievement data, enrolments and completions data from the tertiary education sector, with earnings data in the years after graduation from the Inland Revenue Department, government assistance through benefit dependency data from the Ministry of Social Development, and border-crossings data from Customs. This dataset allows us to track the destinations and earnings of graduates over a number of years after they have lost contact with the institution. This is authoritative population level data on some of the variables we all measure in other ways that is presented in one simple table and tracked over the years. In the first instance, analysis of the data has focused on young graduates as this is a priority group in New Zealand. Through Massey University's participation, however, and because of our interest in data for our slightly different student demographic, we have been able to extend the analysis and utility to include data for all age groups and thus make use of a very comprehensive set of information. This article describes the data governance through Statistics New Zealand, analysis via the Ministry of Education, and the potential utility of the data for one participating tertiary provider.
