Bangkok Christian College was instrumental in early parts of Dr Arthit’s educational journey. From Bangkok Christian College he moved to Chulalongkorn University for his undergraduate studies, in Political Science, Diplomacy, and Foreign Affairs. 

His thirst for knowledge then led him to head to the United States, where he earned a Master of Arts in International Relations from the Fletcher School of Law and Diplomacy at Tufts University in Massachusetts, USA. Additionally, he attained a Master of Public Administration from California State University, Los Angeles, and a Doctorate of Political Science in Public Administration from the University of Colorado, Boulder.
