Our daughter’s first year of schooling was at the 21K School. For all young children, the setting and learning environment are ideal. Every kid receives individualised instruction, and every child’s need is met. Highly recommend the school to other parents and children.

Brendan, Parent,


Emma loves spending time with her wonderful facilitators as they are fun and encouraging. She is cared for, protected, and in an environment that supports her future achievement, so I can feel at peace while she is at school. This is all I need to be assured of, as a parent

Mary, Parent,


Why choose any other school for your child when you can send them to the best school from the comfort of your own home? 21K is a school that offers a real international curriculum taught on an accessible platform! I’m incredibly happy with my parents’ choice!

Augustus, Parent,


I’m 100% happy with the learning provided at the 21K School. With a keen promotion of children exploring a wide range of extracurricular activities in a secure and stimulating learning environment with 3–4 hours of regular online classes 5–6 days a week in small class sizes. What else does your child need to excel?

Jemimah, Parent,


I am generally quite slow with my learning pace. Regular schooling with its 7-8 hours of classes doesn’t work for me as I cannot keep up with the educational pace, unlike my peers in the same age group. Here, all my classes are only 3-4 hours every day! I can take my time to understand and learn. I also receive individualised attention and benefits in ways that no other school could provide. Grateful!

Virgil, 14 years,

Yes, 21K School provides a British curriculum. Our curricular model follows the framework of Pearson, the largest awarding organisation in the UK.

The answer is yes; age can play a role in online learning. Online learning requires self-motivation, discipline and organisational skills to be successful. While it can be beneficial for learners of any age, developing these skills may become easier for younger students who are more accustomed to digital learning.

Online classes are like any other classes, but they're done through an internet-enabled device. Students are taught through digital learning platforms like video conferencing or streaming services. In online classes, the instructor teaches remotely, and the students can access the class anywhere with an internet connection.

Making your child attentive in online classes requires a combination of both parental and student effort.

You should also ensure that your child is well-rested, has adequate breaks, and stays hydrated.

An online school is an excellent option for families who have busy schedules. It can provide flexibility to parents and students alike, allowing them to complete assignments independently and receive quality instruction. Online schools usually use an asynchronous learning model, meaning students can log in to their virtual classroom whenever convenient. They can receive instruction from a teacher in real-time through video and audio conferencing or access resources at any time.
