The first reason is that primary schools in Singapore have adopted the selection principle of survival of the fittest since the first grade, so that children can draw a clear line through learning, thus stimulating their deep-seated struggle. In this way, children can establish a good concept of learning. Only by going forward bravely can they be selected to a senior class, which will play a very good auxiliary role in their future growth. This educational model breaks the conventional "good class intervention principle" and realizes the principle of fair competition, so it is called.

The second reason is that Singapore has its own unique subject arrangement. One of the four courses offered is a mother tongue course, which is devoted to learning one's own language and etiquette system, developing one's own culture and filling children with support and love for the country, while other countries ignore the excavation of their own culture based on the learning concept of quick success and instant benefit. Singapore's primary education has achieved this and won praises from people all over the world, so it is called first-class education.

The third reason is that Singapore adopts an education method that keeps pace with the times, and through education, we can cope with the current situation in time. Because Chinese is widely spread in the world, Singapore's education department requires her to know Chinese when recruiting English teachers, which kills two birds with one stone and attracts much attention, making it a first-class education.
