Aggregated data meta-analyses indicate a correlation between instructional leadership and student achievement. However, it is unclear to what extent this relationship can be generalized across cultural contexts, as most primary studies stem from Anglophone regions. Drawing on international large-scale assessment data, this 3-level individual…

Achievement tests are commonly used in education to evaluate students' academic performance and proficiency in specific subject areas. However, there is a major problem that threatens the validity of achievement test scores which is test-taking disengagement. Respondents provide answers that are inconsistent with their true ability level and can…

Practitioners are encouraged to apply theories of reading development to psychoeducational test interpretation. Orthographic mapping provides an explanation of the acquisition of sight words. Although many test batteries provide tasks for practitioners to assess reading components associated with orthographic mapping, the relationship among…

Although self-report surveys are widely used for data collection, data quality can vary across populations because certain groups are more likely to engage in insufficient effort responding (IER). Our study examined how different levels of the educational system--student groups, schools, and cultural contexts--affect data quality due to IER, using…

The Innovation Schools Act of 2008, § 22-32.5-102, et seq. C.R.S., was designed to provide a pathway for schools and districts to develop and implement innovative practices in a wide variety of areas and contexts to improve student outcomes. The Act provides a formal process that allows schools or groups of schools to make requests to their local…

Purpose: We hypothesize that alphabet learning during early childhood matters for reading and spelling in alphabetic languages. In this preregistered study, we conceptually replicated and extended work on children's alphabet learning trajectories and associations with Grade 1 outcomes. Method: Preschool-aged English-speaking U.S. children (n =…

This study investigates the determinants of educational inequality between OECD and non-OECD countries using data from the PISA 2022 dataset. By focussing on factors such as parental education, perceived socioeconomic status, food security, and access to digital devices, the study provides a comprehensive analysis of how these variables impact…

The PISA 2022 evidence suggests that having a growth mindset is related to positive learning outcomes. However, this positive relationship is clearest among students performing at middle proficiency levels, where belief in improvement aligns with tangible opportunities for progress. For lower-performing students, by contrast, the relationship is…

The ACER Progressive Achievement approach includes PAT assessments that measure what students know, understand, and can do across the domains of Reading, Spelling, Vocabulary, Grammar and Punctuation, Maths, Science, Inquiry and Problem Solving in STEM Contexts, and Critical Reasoning. The results of PAT assessments are available immediately to…

The simple views of reading (SVRs) and writing (SVWs) reflect useful frameworks for the psychoeducational evaluation of literacy difficulties. They describe reading comprehension and written expression as the outcome of oral language, decoding, and transcription skills. Prior research has demonstrated that these components explain the vast…

As low-stakes testing contexts increase, low test-taking effort may serve as a serious validity threat. One common solution to this problem is to identify noneffortful responses and treat them as missing during parameter estimation via the effort-moderated item response theory (EM-IRT) model. Although this model has been shown to outperform…

PISA is an influential international study of the achievement of 15-year-olds. It has a high profile across the devolved nations of the UK, with the results having a substantial impact upon education policy. Yet many of the technical details underpinning PISA remain poorly understood--particularly amongst non-specialists--including important…

Test-based accountability policy in the US has resulted in increased availability and use of assessment systems to support instructional decision making. Though limited, literature to date suggests an important role for these systems as tools, mediating teacher knowledge and action. We examine system log data from NWEA's MAP assessment to better…

Purpose: The overarching purpose of this journal-ready dissertation was to determine the degree to which differences existed in Grade 4 STAAR Writing performance by student economic status, gender, and language status. In the first article, the purpose was to investigate the extent to which student economic status (i.e., Not Poor, Moderately Poor,…

Reducing the socio-economic achievement gap is a key goal of education policy internationally. Since 2017, the stated intention in Ireland is to use the Pobal HP Deprivation Index to identify schools serving high proportions of disadvantaged students. In spite of this, little published research has compared the performance of the HP index to…
