During the reign of Nasser al-Din Shah in Iran, Iranian thinkers became increasingly concerned with the education system. They realized the correlation between reforms in various areas and raising the public’s awareness and discussed the necessity of public education. Consequently, they emphasized the reformation of elementary education as the basis of public education. These thinkers’ approach to elementary education and the relevance of their solutions for reforming elementary education to the realities of the time and the principles of elementary education is the issue that will be studied in the present research by applying a descriptive-analytical method and using the works of the thinkers of that era. This research seeks to answer the question whether the solutions offered by the thinkers of the Nasseri Era to reform elementary education and make it public bore any correspondence to the realities of the time and the principles of elementary education. Results of this research indicate that although the thinkers of that era had a proper conception of the role of elementary education in public education, by insisting on solutions such as reforming the alphabet, they were distanced from the realities of the time and the principles of elementary education.
