Selection effects in the Swedish Scholastic Aptitude Test due to socioeconomic status (SES) were studied using data from longitudinal studies (n=8,222). Results show that subjects from low SES groups constitute the most positively-selected group even though they obtain the lowest test scores. Gender and grade differences are discussed. (MAK)

The effect of different item formats (multiple choice and open) on gender differences in test performance was studied for the Swedish Diagrams, Tables, and Maps (DTM) test with 90 secondary school students. The change to open format resulted in no reduction in gender differences on the DTM. (SLD)

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)

Biosocial influences on sex differences, found for school achievement test results in grades 3 and 6, have been studied by means of opposite-sex twin pairs and singleton controls, attending the same classes as the twins. As expected the opposite-sex twin pairs tend to be more similar in achievement test results in Swedish and mathematics than…

Changes in intelligence among Swedish 13-year-olds during a 20-year period was studied. Results show: (1) the average of spatial and reasoning intelligence has risen; (2) verbal intelligence increased during the 1960s, but declined thereafter; and (3) by the 1980s girls surpassed in verbal ability and equalled in spatial ability.

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…

This report describes the results of adult education students and upper secondary school students on two recently introduced standardized English tests in Sweden. Comparisons of the results are made between these two categories of students because they are entitled to compete, on an equal basis, for admission into restricted intake programs of…

A comparison was made of ability and achievement test results and school grades for 323 pairs of Swedish male and female twins and 740 controls in relation to social background. An interaction effect of sex and social background was found for verbal ability and mathematics test results. (SLD)

Key findings based on data from the Second International Science Study for 19,036 third, fourth, seventh, eighth, ninth, eleventh, and twelfth graders in Sweden are discussed. Findings concerning achievement, attitudes, gender differences, future education, and career choices indicate that science achievement is increasing, and gender differences…

Changes in verbal, spatial, and reasoning intelligence among Swedish 13-year olds were studied from 1960 to 1990. Rising verbal scores until 1980 have been followed by a decline to essentially the 1960 level. Spatial and reasoning results have risen continuously. Gender and social class differences are discussed. (SLD)

As part of a continuing evaluation of the Swedish school system, changes in intelligence test scores from 1960 to 1995 were studied in relation to cohort, gender, and socioeconomic background. Changes in verbal, spatial, and reasoning ability were studied by comparing results on identical tests given to representative samples of Swedish…

A written intelligence test with verbal, reasoning, and spatial subscales was administered to two comparable national samples of 1,000 thirteen-year olds in Sweden, tested in 1961 and in 1966. The increases were greater for girls than for boys, and the changes occurred simultaneously with several changes in social and educational conditions. To…
