Evaluating machine learning for projecting completion rates for VET programs

By Michelle Hall, Melinda Lees, Cameron Serich, Richard Hunt

This technical paper summarises exploratory analysis undertaken to evaluate the effectiveness of using machine learning approaches to calculate projected completion rates for VET programs and compares with the current Markov chains methodology used by NCVER.

Total VET program completion rates

By Brad McDonald

This paper outlines how the methodology used to determine government-funded VET program completion rates can now also be used for total VET activity program completion rates.

Student Outcomes Survey: self-reported graduate model review

By Ben Sanders

This technical paper reports on the 2018 self-reported graduate model review. This statistical model is used to predict whether Student Outcomes Survey participants who self-report as graduates are ‘actual’ graduates according to official definitions.

Linking NAPLAN scores to LSAY

By Davinia Blomberg, Marilyn Lumsden, Patrick Lim, Ronnie Semo

This report looks at whether it is possible to link data from the Longitudinal Surveys of Australian Youth (LSAY) with external data sources to improve the breadth of information available from the survey.

Data linkage and statistical matching: options for the Longitudinal Surveys of Australian Youth

By Nhi Nguyen, Sinan Gemici

Combining the Longitudinal Surveys of Australian Youth (LSAY) with other data sources would enhance the breadth of information without adding respondent burden. This discussion paper explores two issues: the potential for linking data from existing administrative collections, such as Medicare, to LSAY; and the feasibility of combining data from the Longitudinal Study of Australian Children and LSAY via statistical matching.

Measuring student satisfaction from the Student Outcomes Survey

By Peter Fieger

The Student Outcomes Survey is an annual national survey of vocational education and training (VET) students. Since 1995, participants have been asked to rate their satisfaction with different aspects of their training, grouped under three main themes: teaching, assessment, and general skills and learning experiences. In this paper we review and compare three different methods of creating summary measures — Rasch analysis, weighted means and simple means — that encapsulate the three main themes of student satisfaction. We find that all three methods yield similar results and so recommend using the simple means method to create the summary measures.

Weighting the LSAY Programme of International Student Assessment cohorts

By Patrick Lim

This technical paper outlines the methodology used to adjust the original Program of International Student Assessment (PISA) weights to ensure that each Longitudinal Surveys of Australian Youth (LSAY) wave represents the original population. The author also provides guidance to researchers in applying the weights to their analysis of LSAY data.

Getting tough on missing data: a boot camp for social science researchers

By Alice Bednarz, Patrick Lim, Sinan Gemici

Research in the social sciences is routinely affected by missing data. Not addressing missing data appropriately may yield research findings that are either 'slightly off' or 'plain wrong'. This study demonstrates why and how frequently used simple remedies for missing data can impact on research results. The authors provide the target audience (i.e. producers and consumers of social science research) with a step-by-step guide on how to implement multiple imputation, which is the standard method for dealing with missing data. They encourage researchers to carefully consider the potential impact of incomplete information and to use modern missing data methods whenever possible in their own work.

Measuring the socioeconomic status of Australian youth

By Patrick Lim, Sinan Gemici

When measuring the socioeconomic status of young people, the authors find that the SocioEconomic Indexes for Areas (SEIFA) works well when reporting participation in higher education at aggregate levels, but performs very poorly when classifying individuals. This has policy implications because it means that programs directing resources to increase educational participation for those with low socioeconomic status may be doing so based on incorrect information. The data used come from the 2003 cohort of the Longitudinal Surveys of Australian Youth (LSAY), looking at young people aged 15 to 25 years.

Individual-based completion rates for apprentices

By Tom Karmel

Low completion rates for apprentices and trainees have received considerable attention recently and it has been argued that NCVER seriously understates completion rates. In this paper Tom Karmel uses NCVER data on recommencements to estimate individual-based completion rates. It is estimated that around one-quarter of trade apprentices swap employers during their apprenticeship. Taking this into account, Karmel estimates completion rates for individuals, ranging from 39.2% for the food trades to 64.2% for electrotechnology and telecommunications trades workers. He notes that employer churn is an issue, with the worst occupations being hairdressing and the food trades.

Tradespeople for the resources sector: projections 2010-20

By Peter Mlotkowski, Tom Karmel

This paper was prepared for the Australian Government's National Resources Sector Employment Taskforce, which was created to investigate the extent to which skill shortages might impact on the development of the resources sector. It applies historical apprenticeship commencement rates to population projections to provide an estimate of the number of tradespeople likely to be working in the resources sector between 2010 20 at a detailed level and by region.

ANZSCO imputation in the National Apprentice and Trainee Collection

By Brian Harvey

This technical paper provides informaton on the methodology used to back-cast the Australian and New Zealand Standard Classification of Occupations (ANZSCO) codes on historical data in the National Apprentice and Trainee Collection.

Estimation of apprentice and trainee statistics

By Brian Harvey

This technical paper provides information on the methodology used to estimate apprentice and trainee figures for NCVER publications reporting apprentice and trainee statistics. The new estimates were established following a major review of the estimation method used in the past and were endorsed by the National Training Statistics Committee in September 2004.
