Testimonials
As parents of our two daughters Belle and Book, we are very impressed that our daughters have studied at Lertlah School starting from K.1 until Grade 6. The teachers take good care of every student with love and kindness. They are very friendly and willing to listen to parents and students. Lertlah School works closely with parents so that parents know everything about what their child has done at school, as well as the child’s development, and academic strengths and weaknesses.
As parents, it is difficult to know which school is best for your child. The first feeling that I got from Lertlah School was being welcomed. You can see everyone smiling throughout the school. Students are happy, which is the most important thing for us as parents. Finally, I chose Lertlah School because I love the Lertlah teaching style.
The mother has four daughters, all studying at Lertlah. The triplets — Rita, Risa, and Rilin — are in kindergarten. Although they sometimes cry when going to school, the teachers always find ways to make learning fun so the children are excited to attend.Our family truly appreciates the warm and caring atmosphere at Lertlah. The teachers nurture the children’s academic and language skills, while also encouraging them to be confident and expressive. Whenever issues arise, communication with teachers is very easy. Progress reports are regularly shared so parents can follow their children’s development closely. This gives me complete confidence in entrusting all four of my daughters to Lertlah.
Their mother praises their outstanding English skills, as well as their excellent Thai. With this strong foundation, both boys continued their studies successfully in secondary English Programs, progressing smoothly toward university entrance. She is impressed by how the LIPS curriculum equips students with both English and Thai proficiency, setting them apart from students at other international schools.The mother expresses deep gratitude to the teachers for their loving care and dedication, which helped her sons excel both academically and personally.
Parents of twin boys, Theemetha and Thammethee, chose Lertlah because it is close to home and offers an English Program with native-speaking teachers. Once enrolled, they knew they had made the right choice. The boys can now understand and communicate in English confidently, and their overall development has progressed in a very positive way. The parents admire the Thai teachers for their close, individualized attention to every child, as well as the friendliness of all staff members. They describe Lertlah as a small, clean, safe school with a warm and nurturing environment. They trust the school fully with their children’s education.
After considering many schools, this family decided that Lertlah was the best fit. They value the safe and supportive environment, attentive teachers, and diverse activities that help children grow academically, socially, and emotionally. Their daughters come home every day happy, eager to share their experiences, and excited to go back to school each morning. The parents are also proud of the LIPS curriculum, which builds strong English skills in reading, writing, listening, and speaking, giving their children greater confidence. In addition to academics, the school instills good manners, religious values, and cultural appreciation through a wide variety of activities that also welcome parental involvement. The family is confident they made the right choice and feels grateful to Lertlah for bringing joy and growth to their daughters.
The mother, recommended by friends, enrolled all three of her children in Lertlah’s International Program (LIPS). She was impressed from the very beginning.Why they chose Lertlah:English is essential, and children must start young to develop fluency. Her children began in nursery, and by Kindergarten 2 they were already speaking English with friends.The school encourages self-expression. Foreign teachers create open opportunities for learning, while small class sizes ensure personalized attention. She recalls how the nursery teacher once carried her crying child around the school until she felt comfortable — a memory that left a lasting impression.The tuition fees are very reasonable compared to the quality of education and care provided, especially for families with multiple children.
Lertlah School Kanchanapisek Road provided my three kids many things. Knowledge, critical thinking skills, and self-confidence have been implanted in them ever since they were in kindergarten level all the way to middle school. However, the most important thing is the love and support from teachers and fellow students. These perfect combinations create a society filled with lifelong friendships.
Ever since my children started their studies at Lertlah School Kanchanapisek Road, they are increasingly responsible and self-motivated. They become more confident in expressing themselves. Teachers here are caring, compassionate, and very friendly towards students. This school encourages my children to be creative and imaginative, which are core skills for them to branch out into new horizons in their life.
Here at Lertlah School Kanchanapisek Road, all of my three daughters are well educated. My kids are happy, and at the same time diligent. There is no need for extra outside lessons because everything they need is ready for them here at school.
Six years ago, I faced a very difficult decision to make – “Where should my children’s 2nd home be?” Six years have passed, and I have never regretted the decision I made then. Right now, my 2 kids are happy in their 2nd home where they have reached their highest potential that exceeds my expectations.
– Lessons and academic content taught in Lertlah School have benefited students by building important social, physical & cognitive skills. Furthermore, curriculum programs in this school are suitable for students of all ages. The students are regularly taught problem-solving skills, which is useful to students of all ages. – In terms of Classroom Management, Gimmick has been taken care of very well by homeroom teachers. As a parent, I trust the school and feel comfortable sending him to school every single day. Gimmick has engaged successfully in academics & learned good discipline. He is also able to develop both his IQ, EQ to a high level for his age.
Academically, Lertlah School offers an English Program in accordance with the Ministry of Education and classrooms are run by Thai & foreign teachers to help students learn through various activities Moji’s favorite subject is English and she is able to speak English fluently after studying at Lertlah School Kaset-Nawamin Road. In terms of classroom management, Moji has been taken care of very well by homeroom teachers. Morality, culture, and manners are also cultivated in students along with academics, thus, Moji has been taught how to manage her responsibilities and display honesty and respectfulness. Lertlah School always welcomes feedback and suggestions from parents
A good school that a child wants the most is the school that makes him or her feel happy with effective programs and knowledge to share. The important things that I look for in a school for my child are: 1.Hygiene and safety 2.Most English Teachers who teach programs are Native Speakers and the proportion of English used is sufficient to enable students to communicate effectively. 3.There are activities for parents to meet with teachers. Parents can monitor the development of their children after classes. 4. Average percentage of Green areas for students that are constantly being improved and are clean. I, like all parents, want my children to be happy when in school and to be able to help themselves efficiently after graduating from school. Thanks to Lertlah school Kaset-Nawamin! I am happy I chose this school for my child and I know that I made the right decision.
My children are very happy to come to school every day, and they have good academic grades in both Thai and English. Just recently, I have enrolled my youngest child at Lertlah School Kaset-Nawamin Road.
