In this research, alternative education systems have been investigated in order to provide engineering education and general vocational education in accordance with the requirements of modern age at both secondary and high education levels. After different vocational education practices in the world have been mentioned, the impact of starting engineering education in high school has been measured by “causal-comparative” method in order to educate more qualified and high practice skilled engineers in engineering faculties. For this purpose, the success of the students who entered engineering faculty as a graduate of vocational high school was compared with the other students. The effects of engineering students’ taking vocational courses at high school level were analyzed with graphs and it is found that it is more beneficial for engineering students to have vocational education at high school level. For a more developed industry, various suggestions have been made for the training of engineers who make up the executive and expert staff and the technicians who make up the labor force.
