This study aimed to investigate the type of personalities that students had and the relationship between personality type with future anxiety and students' achievement. The sample of the study consisted of 304 students from Tafila Technical University and Al-Hussien Bin Talal University. The researchers used the big five scale which was developed by Costa and McCrae (1992) and adapted by Al-Ansari (1997). The results indicated that the most popular personality trait was conscientiousness and the least one was neuroticism. There was a statistically significant difference in agreeableness personality attributed to gender in favor of female students. Future anxiety level was mid and it was negatively correlated with the extraversion, openness to experience, agreeableness, and conscientiousness and positively correlated with neuroticism. Finally, the result indicated that differences involving achievement were statistically significant in favor of female students, and there was not a statistically significant difference in means of future anxiety attributed to gender.
