Preface
Professional Training is one of the most important parts in the program which is required fourth-year students to undergo their internship in the government or private sectors in Thailand or other country with the approval of the university. It focuses on daily-life experience at workplace. What we familiar with and what we do not. It normally lasts two months; however, it is enough for recent graduated students to prepare for their future career.
