Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

The reading literacy skills of Australian adolescents, as measured in successive PISA waves, have declined since 2000. Literacy achievement is not low by international standards, but it is lower in Australia than it is in Anglophone countries with which we compare ourselves, e.g. Canada. Using PISA 2018 and PIRLS 2021 data, we investigated both…

While the relationship between school socioeconomic composition and student academic outcomes is well established, knowledge about differential effects is not extensive. In particular, little is known whether the relationship differs for students with varying levels of academic performance. We examined whether the school socioeconomic composition…

By the end of 2021, more than 168 million students across the globe had missed a year of face-to-face schooling due to the COVID-19 pandemic. In NSW, Australia, most students engaged in learning from home for eight weeks during 2020 and a further 14 weeks during 2021. This study provides robust empirical evidence on how two years of disruptions to…

We investigated effects of tracking students into higher, more academic, and lower, less academic, school types immediately after primary school (early tracking) instead of having a comprehensive secondary school system (late tracking) on school gender segregation and gender gaps in achievement outcomes. We assumed that, in early tracking…

Australia participated in the eighth cycle of the Trends in International Mathematics and Science Study (TIMSS). TIMSS is an international sample study that assesses the mathematics and science achievement of Year 4 and Year 8 students every 4 years. Australia has participated in all cycles of TIMSS since it commenced in 1995 and over this 28-year…

Families are active agents in school systems and apply different strategies of educational advantage to help their children succeed at school. These strategies are planned and enacted by families with their children in mind, but they are always a response to the broader education system design. This article explores how through their strategies…

In this 21st century context, communities and nations cannot afford to lose the talents of any young people. Shifts in thinking and practices are needed: from one-dimensional definitions to varied talents and 21st century skills of creativity, critical thinking, collaboration, and communication; from identification to assessment; from the goal of…

The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study of student achievement directed by the International Association for the Evaluation of Educational Achievement (IEA). TIMSS was first conducted in 1995 and the 2023 assessment formed the eighth cycle, providing 28 years of trends in mathematics…

Developing students' reading and numeracy skills remain key goals of contemporary schooling. In Australia, the National Assessment Program -- Literacy and Numeracy (NAPLAN) tests have assessed these skills since 2008. Previous research found a significant gender gap in favour of females for the NAPLAN writing test, yet no study has examined…

Objective: We aimed to examine the psychometric properties of the Scale of Perfectionism and Excellencism (SCOPE) in a novel sample, Australian adolescents. Method: The cross-sectional sample consisted of 350 participants (79 male, 271 female; mean age 17.9 years, age range = 15-20 years) from a secondary 10 school and university who completed a…

Apprenticeships remain an important source of skilled workers in Australia; however, commencements have not kept pace with the skills demand projected in the previous decade. During that same decade, undergraduate university enrolments grew considerably. In investigating whether young people who would previously have chosen an apprenticeship have…

Background: Comparative educational research has studied inequality in educational outcomes through large-scale assessments like PISA and TIMSS, by identifying achievement gaps within social groups (e.g., gender, parental education, and immigrant gaps) to inform investment in intervention programs and educational policies. However, the focus of…

It is well understood that when students are experiencing hunger, their ability to learn suffers. What is less understood is why this is the case and the role of the learning environment. Using Trends in International Mathematics and Science Study (TIMSS) 2019 data, this brief examines how student hunger is correlated with how disorderly the…

The purpose of this study is to examine the effect of missing data imputation methods, namely regression imputation (RI), multiple imputation (MI) and k-nearest neighbor (kNN) on differential item functioning (DIF). In this regard, the datasets used in the research were created by deleting some of the data via the missing completely at random…
