Investigated cultural and sexual differences in test anxiety (TA) in 296 male and 356 female 11th-12th graders from Egypt, Brazil, and the US. Measures of trait anxiety and trait arousability were also included. Compared to the US, greater TA was found in Egypt on both the worry dimension and the emotionality dimension. Greater TA was also found in Brazil, but only on the emotionality dimension. Compared to both the US and Brazil, greater trait anxiety and arousability were reported by high school students in Egypt. In all 3 cultures females reported greater worry, emotionality, trait anxiety, and arousability than males. A possible explanation for the cultural differences in TA is the important consequences of high school testing in Egypt and Brazil.
