The reason why church schools developed rapidly in the early 20th century

1. First of all, church schools were one of the major forces in the field of education at that time, and they enjoyed a high status and reputation in the community.

2. Secondly, due to the accelerated development of industrialization and urbanization, a large number of immigrants have poured into cities, requiring education for their children.

3. Then, missionary schools became a good choice because they provided education in religious beliefs and moral values, which were considered very important at the time.

4. Finally, many parochial schools offer similar curriculum to public schools and often have smaller class sizes and better teacher-student ratios.
