The best way I have of knowing how well the school is doing is through my daughter. She’s not only succeeding academically, but she’s also happy and has made several good friends. Being the shy girl she is, 21K World School’s conducive learning resources have helped my child overcome various barriers. I will be forever grateful to 21K.

Jose, Parent,

21K World School is one of the fantastic schools I have been a part of. I had the opportunity to learn English from native English facilitators. Everything about 21K is great. I just love being a part of this revolutionising education community.

Isabella, 14 years,


It was an easy choice to choose 21K World School. Once I read about it, I simply knew I wanted my son to be a part of an educational community that would accept him for his differences

Juanita, Parent,


The best part of 21K School is the sense of community and friendliness that I experienced here. It has helped me overcome my shyness and become someone who is comfortable and proud to be who they are. I recommend 21K World School for its friendly atmosphere, relatively small class sizes and easy and direct communication with teachers.

Miguel, 15 years,


We came to 21K World School as first time parents with a narrow understanding of early childhood development. What we found was a community of like-minded parents and facilitators who celebrate the uniqueness of every child. As parents we continue to learn a great amount from the school’s programs which have given us the tools to guide our children at this early and impressionable age.

Juan Pablo, Parent,

Here are some steps you can follow to finish high school online:

Research online high schools: Several online high schools offer programs for students to complete their high school education entirely online. It’s essential to research the options available and choose a school that meets your needs and aligns with your goals.

Meet the eligibility requirements: Most online high schools have specific eligibility requirements that students must meet to enrol. These requirements may include having a certain grade point average or passing a placement exam. Make sure to meet these requirements before enrolling.

Enrol in the school: Once you have chosen an online high school and met the eligibility requirements, you can enrol. This may involve completing an online application, paying applicable fees, and submitting transcripts or other required documents.

Set up a dedicated workspace: It’s essential to have a quiet, distraction-free space to focus on your studies. This could be a separate room or a designated area in your home.

Establish a routine: Having a regular schedule can help you stay organized and on track with your coursework. Set aside specific time for studying and allocate enough time for each task each day.

Stay connected: Online schooling can be isolating, so staying connected with your classmates and teachers is essential. Participate in online discussions and ask for help when you need it.

Use available resources: Most online schools will provide a range of resources to support your learning, such as videos, lectures, and reading materials. Make sure to use these resources to help you understand the material.

By following these steps, you can set yourself up for success in your online high school education and work towards completing your high school diploma.

There are a few different ways you may be able to obtain your school records online, depending on your situation. Here are some options to consider:

Contact your school: If you are a recent graduate or are currently enrolled in a school, you may be able to request your school records online through the school’s website or by contacting the school directly. Many schools have systems for students to request and access their records online.

Use a transcript service: Some schools may use a transcript service to manage and distribute student records. If your school uses a transcript service, you may be able to request and access your documents through the service’s website.

Use a third-party service: Several third-party services can help you request and access your school records online. These services may charge a fee, but they can help you quickly obtain your documents.


It’s important to note that you may need to provide certain information or documents to request your school records online, such as your name, date of birth, and school name. You may also need proof of identity or authorisation if you are not the student whose records are being requested.

Online schools have several potential benefits that may make them a good option for some students. These benefits can include the following:

Flexibility: Online schools often offer more flexibility regarding when and where students can complete their coursework. This can be especially useful for students who have busy schedules or live in rural areas where access to schools may be limited.

Customization: Online schools often allow students to customize their learning experiences by providing a range of courses and learning materials. This can be helpful for students who learn best in different ways or have unique learning needs.

Convenience: Online schools can be a convenient option for students who don’t have to commute to a physical campus, saving time and money.

Self-paced learning: Online schools may allow students to work at their own pace, which can benefit students who need more time to complete coursework or learn quickly.

Access to a broader range of courses: Online schools may offer a more comprehensive range of courses than traditional schools, which can be helpful for students interested in subjects not offered at their local school.

21K School provides a way for students to complete their education online. We offer a range of courses and programs, often including traditional academic subjects such as math, science, and English, as well as elective courses in art, music, and physical education. Online schools generally work by providing students with access to course materials and assignments through a learning management system (LMS) or other online platforms. Students can typically access these materials anytime, allowing them to complete their coursework on their schedules. Online schools may also offer support services such as tutoring, counselling, and technical assistance to help students succeed. Some online schools may have set schedules for live, interactive classes. Learn more here:

The cost of online high school can vary widely depending on several factors, including the specific school, the location of the school, and the type of program being offered. Some online high schools may be free for students, while others may charge tuition. The Fee Structure and Policy at 21K School are simple, affordable and pragmatic, with multiple payment options and terms. Visit our Fee Structure and Policy page to learn more.

You can apply under all programmes with an option to study full-time or part-time, subject to the availability of seats. Age will be one criterion to ensure appropriate grade placement, especially in the Early Years and Cambridge Primary. Relaxation in age and Grade Acceleration may be offered case-to-case basis as determined by our School Counsellors. Learn more about our Admission Journey here.

One of the best options for students who want to graduate early is to take advantage of online learning opportunities. With some research and dedication, you can find a course or program that will work for your goals. Online courses are often more flexible than traditional educational programs, allowing you to work at your own pace and progress faster. Plus, the interactive nature of online learning makes the experience more engaging than sitting in a classroom.

To check if an online school is accredited, you can do the following:


Look for accreditation information on the school’s website.

Check the accrediting body’s website to verify the accreditation.

Search the U.S. Department of Education’s database of accredited schools.

Check if the accrediting body is recognized by the Council for Higher Education Accreditation (CHEA).

Fees at 21K School must be paid online through the Invoice/ link provided. All payments must be made online using our payment link. We do not accept cash/cheque/demand drafts. 10% of the School Fee Component is collected during admission. The rest is payable in two equal instalments as per the following schedule:

  1. 30 days before the end of Semester 1
  2. 30 days before the end of Semester 2

The Learning Kit Fee is payable at the time of admission. It includes a physical kit, digital resources and shipping charges.

Whether a traditional or online school is “better” depends on individual factors such as learning style, schedule, and personal preferences.  Traditional schools offer face-to-face interaction with instructors and classmates, while online schools allow students to learn at their own pace. Both types of schools have advantages and disadvantages, so it’s important to evaluate all options before making a decision.
