Extended time is a commonly-used test adaptation for standardised high-stakes tests. In this study, extended time provided for test-takers with dyslexia is examined. Data from standard versions of the Swedish Scholastic Aptitude Test (SweSAT) and data from test administrations where extra time is provided was used. Indications are that the…

This paper investigates measurement invariance as it relates to migration background using the Program for International Student Assessment measure of social belonging. We explore how the use of two measurement invariance techniques provide insights into differential item functioning using the alignment method in conjunction with logistic…

The pupils' attitudes toward technology survey (PATT) has been used for 30 years and is still used by researchers. Since it was first developed, the validity of the questionnaire constructs has primarily been discussed from a statistical point of view, while few researchers have discussed the type of attitudes and interest that the questionnaire…

Gender fairness in testing can be impeded by the presence of differential item functioning (DIF), which potentially causes test bias. In this study, the presence and causes of gender-related DIF were investigated with real data from 800 items answered by 250,000 test takers. DIF was examined using the Mantel-Haenszel and logistic regression…

Differential item functioning (DIF) for an item between two groups is present if, for the same person location on a variable, persons from different groups have different expected values for their responses. Applying only to dichotomously scored items in the popular Mantel-Haenszel (MH) method for detecting DIF in which persons are classified by…

The Autism-Spectrum Quotient (AQ) is among the most widely used scales assessing autistic traits in the general population. However, some aspects of the AQ are questionable. To test its scale properties, the AQ was translated into Swedish, and data were collected from 349 adults, 130 with autism spectrum disorder (ASD) and 219 without ASD, and…

The education systems in Sweden and Finland have different formal and informal testing traditions. A recognised possible adverse effect of testing is test anxiety among pupils and students which may have a negative impact on examination performance. Research into which factors of testing practice affect the levels of test anxiety in younger pupils…

Previous studies indicate that a worldwide measurement tool may be developed based on the International Classification of Functioning Disability and Health (ICF) Core Sets for chronic conditions. The aim of the present study was to explore the possibility of constructing a cross-cultural measurement of functioning for patients with low back pain…

To determine whether or not there are systematic differences in the psychometric properties of items in the vocabulary test of the Swedish Scholastic Aptitude Test, data from test administrations from 1984 through 1988 (over 50,000 students) were analyzed. The systematic relationships between word characteristics and psychometric properties are…

Within-family estimates have been considered a remedy to selection bias in estimates of long-run consequences of teen motherhood. A major critique, however, is that heterogeneity within the family might still bias the estimates. Using Swedish data on biological sisters, I revisit the question of the consequences of teenage motherhood. My…

Reports on recent changes in examination policy and practice in China, England and Wales, the Federal Republic of Germany, France, Japan, Sweden, the United States, and the Soviet Union. Identifies and discusses some significant trade-offs arising from the implementation of examination policy. Discusses four nearly universal dilemmas of…

Whether gender differences in Swedish Scholastic Aptitude Test results changed with the age and experience of new examinees was examined for 7,779 male and 7,294 female students, including those under age 24 newly eligible for the examination. No real differences were found for traditional age group and younger examinees. (SLD)

The Swedish Scholastic Aptitude Test (SweSAT) has been in use as a selection instrument for higher education since spring 1977. One of the greatest problems with the SweSAT is the gender difference in results. A number of studies have been performed in order to clarify where and why these differences are found. This paper summarizes these studies…
