Next, I would like to tell you a story. In a particular city, there are many schools, some are elite schools, and some are ordinary schools while some are not as good as the others. Among them, there are two famous elite schools. And they were set up 40 years ago. Recently, these two elite schools have changed their board of directors, and they are able to do so because they are independent secondary schools. Let me talk about the first school. It is called Bee Wah Secondary School. The directors feel that since Bee Wah is already one of the top schools in Singapore, there is no need to look for the best principal and the best teachers to come to the school. Furthermore, if the teachers join the school, they should be committed and should sacrifice themselves in education. They should be the engineers of the human souls. Not only that, the board of directors decided that the salaries of the principal and teachers should be linked to the results of the lowest bottom 20% of the students. If they get more than 50 marks, the teachers would be paid $2,500 per month, ie, $50 for each mark. So if the students get 30 marks, the salary should be $1,500; if they get zero, their teachers should not be paid. Think about that. What would be the results? When Bee Wah Secondary School wants to recruit teachers, would they get good teachers to respond to them? Not only would they not get good teachers, even the existing teachers would spend all the resources to look after the weakest students. All the good students would go to other schools, because they had been neglected. So this resulted in the loss of talent and eventually Bee Wah Secondary School may have to close its doors.
