This booklet is a state of compulsory education and high school education in Cambodia. In the early 1990s, it seemed to me that elementary school students, in lower grades, upper grades, and through all grades, it was natural to retire and drop out of school. That's how very unthinkable words existed in conversations with the people I touched in front of me. I confirm whether it is true to put the situation of the school into words one by one. Therefore "Is this really true?" It was a strange, shocking matter which reflected in the mind to me. So， it was hard to reflect on me as it was in front of me. No, I am not hearing that the things in front of me are never difficult. However, I do not understand that. It took me a considerable amount of time to understand that. I've never experienced that. That was how hard it was for me to imagine. "It started with the fact that the grades and ages didn't fit." The cause starts with the intertwining of age and grade. It has happened in my head that the school year and age beyond it have not always been linked for several years. For instance, it becomes like this in the elementary school in the country where it is rich. "If you're in the first grade of elementary school, you're six or seven." However, such an age does not pass. Cambodian people didn't have a chance to go to elementary school. The reason is that people in Cambodia's childhood were civil war. Otherwise, Cambodians will return from refugee camps and other countries in the world. As a result, Cambodian people suddenly come to live in Phnom Penh, a local city, and a local farm village part, etc. At that time, if you are the person, you are ten years old. Or, it was a daily thing to be older than that. At that time, the people who fall will go to elementary school, "How many grades can this student enter school?" Because of this, the people who fall under it will enter elementary school. What has been lost is large for people by the civil war. A very daily idea does not become known to a lot of people when there is a reality of civil war, the war, and hunger like that. People who have no experience have no way of doing what is. As a foreigner, I have no experience, but as a concrete thing, I can't grasp what is happening in front of me. The people in front of me spent time in a range of lives I couldn't imagine. Then, I understand that the mysterious educational environment had expanded later. Meanwhile, in the early 1990s, there was no such thing. Then, I had spelled those days. Because, it is like this. "I understand, I don't know." It continues single-mindedly. Then, the is that I do not understand that as consideration. Such a thing ran continuously in my mind. More than25 years have passed since then. The educational environment of the capital Phnom Penh is surely advancing. Therefore, I recorded what I noticed newly and what had continued up to now. In this book, I have seen and heard about the education again in the capital and the local city in the past few years. Still, I am made to notice that the educational environment is advancing in a new living environment. The educational situation that I see in capital Phnom Penh looks fresh. However, the educational environment in the pagoda before is reflected in me as Cambodian people take over, and it grows up.
