There was a time that a school was only considered to be good if it produced a lot of students who achieved the highest marks but now thanks to awareness that perspective has changed. It is not that achieving high marks is a bad thing because it is not but now good schools focus on the personality of the student too and do not just test his memory. The examinations that were set before in the schools were set in such a way that it was more a test of memory but now schools focus on testing the intelligence and creativity of a student.
A good school’s aim should be to nurture student in such a way that he/she becomes the best version of himself/herself. It should allow student to spread their wings and test out their aptitude and hone their skills so that they can not only succeed in life but also become happy and content. Such a school is located in Bangkok and is called Bangkok Prep. You can visit the website http://www.bkkprep.ac.th/ and you will see that they do not keep the students glued to the textbooks. Some ways that you can sniff out good schools are:
An online research would give you a quick access to how the school works and what it values the most. You should focus on the sections where the school talks about its mission and aim to understand the mindset. You can also read reviews from parents on different forums to glean what type of school it is.
Visit the School
If you like some school then it is a good idea to visit them and try to talk to the teachers there about their focus and teaching style. Also try to see the syllabus that they concentrate on.
