The study aimed to identify the level of vocational identity and uncertainty among grade-nine students in the Governorate of North Al Batinah in the Sultanate of Oman, and to investigate any differences that may exist in the levels of vocational identity and uncertainty due to the variables of gender, family income, and students birthorder. The study also aimed to explore the relationship between vocational identity and uncertainty, and if vocational identity can be predicted from uncertainty. A random sample of 497 students from grade-nine was selected. To achieve the objectives of the study, the vocational identity status assessment and the uncertainty response scale were used. The validity and reliability of the two scales were confirmed. The results of the study showed that the level of vocational identity among the grade-nine students was high in general, while the level of uncertainty was average. There were no statistically significant differences in the level of vocational identity and the level of uncertainty due to the gender variable, while there were statistically significant differences in the level of vocational identity and the level of uncertainty due to the variable of family income. The results of the study also showed that there were no statistically significant differences in the level of vocational identity due to the variable of students' birth order, while there were statistically significant differences in the level of uncertainty due to the variable of birth order. The results also revealed that there was no statistically significant relationship between vocational identity and uncertainty, while the results showed a statistically significant relationship between two domains of uncertainty and the level of vocational identity. Vocational identity can be predicted through two domains: desire for change and cognitive uncertainty. In light of the results, some recommendations and suggestions were documented.
