One of the most significant aims of universities is to educate experts for entering the business market and applying their knowledge in developing the economy of the country. Accordingly, higher agricultural education has a very colossal role in development of the agricultural and employability skills among the students of this field. Therefore, in the present study, employability of the students of agriculture extension and education of Tehran University has been investigated, based on various observational dimensions of Ajzen's theory of planned behavior, attitude, perceived behavioral control, subjective norm and intention. For this purpose, 42 students of agriculture extension and education of Tehran University reported their information according to the elements of Ajzen's theory. The data supported and reaffirmed Ajzen's theory. The first anticipant of the employability was the control of students' perceived behavior. In the same way, intention toward employability was the most considerable anticipator of the employability behavior.
