This report, supported by the Tertiary Education (TEC), captures the findings of four separate sub-reports on Waikato Institute of Technology (Wintec) literacy and numeracy assessment tool (LNAT) data collected from 2011 to 2014. We outline the research questions, research methods, main findings, conclusions and recommendations. First, we argue a case for TEC to adopt a multivariate layout for the LNAT data-extraction file, and to implement appropriate naming conventions for assessments. Second, we show the impact of a time factor on the TEC's gain calculation algorithm, with the so-obtained results far more positive than would otherwise be the case. Next, we report on the level of association between LN scores and module completions. Last, we report our tentative findings on a multivariate statistical model for predicting learner success.
