My name is Finlay, I am in Year 5 and I love school. My favourite subject is Computing and I enjoy making games and debugging programes

I am in Year 5 and I love Harrow International School Bangkok. I love all the facilities like the swimming pools, tennis courts, gymnasium and music rooms. The teachers in Pre Prep really care about me and make the lessons fun. My favourite subject is Computing. Mr Knight taught us how to write codes and now I enjoy making games and debugging programs. I also like the leadership opportunities here. We get to take on a range of responsibilities, for example, my brother has been a student councillor and I am a tour guide and Byron Vice-House Captain. I feel proud to be a leader at Harrow Bangkok and feel like I have achieved something

We joined the school 5 years ago.

We joined the school 5 years ago. We had a good impression of Harrow Bangkok from an Open House event, especially the facilities. Also we noticed that the children here are very nice, and would say hello to parents and staff - they obviously feel happy being in the school. Most importantly, I knew my children would fit in at Harrow Bangkok. They have lovely friends here, and they love going to school every day. We like the fact that children are encouraged to try lots of new things. My daughter chooses lots of different after-school activities – she does an activity every day of the week… gymnastics, basketball, swimming, art. It’s great that we don’t need to go outside the school community for any extra activities. My son really enjoys music and sport, which is fantastic as before he joined Harrow Bangkok he was more focused on academic studies. He played in his band at the Benefit Bash which was a highlight for us, and he loves basketball.

My daughter loves schoo

My daughter loves school — she has always been an alert and energetic child, and she loves reading. She has really developed her reading skills since she joined Harrow Bangkok, and her English language skills continue to improve impressively in Year 2 - English language skills are so important. When choosing the right school for my daughter, my wife and I decided to send her to an international school, not only to become bilingual, but also to make connections with other children that will last for life. I was very impressed by the child-centred approach to education at Harrow Bangkok. Having an education at a top international school like this is the first window of opportunity. I am so pleased to see the confidence students have here when interacting with each other and with older children and their teachers. When we made the decision to join Harrow Bangkok, we looked at the teaching quality, the credibility of school, and most importantly somewhere where we knew our daughter would fit in. We love the balance between academic and extra-curricular activities here. The emphasis on leadership skills is also one of the reasons we chose Harrow Bangkok. We see her education as an important investment for her future.
