Abstract
From the population of all male Swedish residents born 1973–1976 registered in the census 1985 and with complete test scores from military conscription the following study groups were identified Korean adoptees n = 320 nonKorean adoptees n = 1125 siblings children born by adoptive parents n = 190 and Swedish majority comparisons n = 142024 Global scores from intelligence tests at conscription were compared with grade points from the last compulsory school year year 9 Linear and logistic regression was applied in statistical analysesThe mean grade points in theoretical subjects were lower in nonKorean adoptees than in the majority population but when global test scores from military conscription were adjusted for outcomes were significantly better equal for physics than in the majority population The grade points of Korean adoptees were higher than in the majority population and the same held true after adjusting for global test scores When SES was taken into account the risk of poor school performance only completed lower subject levels increased in nonKorean adoptees compared to models only adjusted for age and sex
