What Makes a Good International High School?

One of the characteristics of a good school is qualified and competent teachers. The teachers must have the required experience to enable the students to succeed. Then, they’ll be able to breed academic and morally intelligent students.

A good school should have a conducive learning environment and state-of-the-art learning materials. It’s only when the environment is peaceful and conducive that students can learn effectively.

Having extra-curricular activities for its students is another characteristic of a good school. These activities include skill acquisition, sports, school clubs, etc. After all, all work and no play make Jack a dull boy.
