During the Pahlavi era, particularly under the reign of Mohammad Reza Shah, Iran's educational system underwent significant transformations, with high schools playing a central role in secondary education. The educational programs were designed in such a way that an Iranian high school graduate often possessed a higher level of literacy and knowledge compared to many high school graduates from Western countries. Comprehensive and extensive educational curricula, focusing on subjects such as sciences, mathematics, foreign languages, and humanities, ensured that students were well-prepared with strong academic and cultural foundations.

One of the notable initiatives of this period was the hiring of English-speaking teachers from Western countries, whose native language was English. These teachers were brought to Iranian high schools during the summer to provide free English lessons, helping students enhance their language skills and become acquainted with international standards of language learning. This initiative significantly improved the quality of English education and provided students with better opportunities for future academic and professional endeavors.

Beyond academic focus, high schools during the Pahlavi era placed special importance on sports and scouting activities. Sports were considered a fundamental part of students' physical and mental development, and diverse programs were established to encourage youth participation in various athletic activities. Additionally, scouting played an essential role in fostering teamwork, discipline, and leadership qualities among students. These programs contributed to nurturing a capable, committed, and community-oriented generation.

Overall, the Pahlavi era's investment in education and the development of modern infrastructure significantly contributed to producing a skilled workforce and advancing the cultural and scientific growth of the country.
