A different way to learn

Learning designed around home life

Self-paced study

Students work through online lessons at their own pace, with coursework and progress available for families to review.

Parents stay informed

Parents monitor progress and support the student's routine. The platform records coursework and calculates academic results; parents do not assign grades.

Lessons with clear learning goals

Teaching lessons identify the academic standards they address. Standards mapping describes lesson alignment; it does not promise recognition or credit in another school or country.

What families get

Rich, growing lessons

Grades 1–12 are open today with 3,508 published core lessons in English, maths, science and social studies — about 2,973 hours of narrated lessons with practice. Each lesson is narrated with pictures, has practice with instant AI marking, and names the academic standard it addresses.

Grade 1: 405 lessons, about 241 hours
Grade 2: 421 lessons, about 248 hours
Grade 3: 470 lessons, about 376 hours
Grade 4: 475 lessons, about 380 hours
Grade 5: 461 lessons, about 369 hours
Grade 6: 517 lessons, about 521 hours
Grade 7: 390 lessons, about 404 hours
Grade 8: 76 lessons, about 82 hours
Grade 9: 74 lessons, about 89 hours
Grade 10: 74 lessons, about 89 hours
Grade 11: 74 lessons, about 89 hours
Grade 12: 71 lessons, about 85 hours

Every grade grows while your child is enrolled, towards the School's standard of about 640 hours of lessons and 160 hours of projects; lessons, practice, tests and projects are added as they are ready for publishing.

How marking works

Practice and tests are marked by AI straight away; a second AI model checks a sample, and anything either model is unsure about goes to a person.
Reviewers hold a teaching licence or a university degree; Grades 7–12 are reviewed by someone qualified in that subject.
A grade is passed on steady work across the year — completion in hours against the School's standard (or against what is published, if that is less) and the average of the best marks, retakes welcome — never on one exam. Projects count as one course. Results are calculated by fixed rules, not by AI.
You can ask about any mark: the first review is by AI and free; a review by a person can be requested for a fee shown before you ask.

Your role as a parent

You supervise your child's study day, read the weekly or monthly progress email, and review each grade before it is confirmed. Projects are part of every grade: you mark them yourself against each project's rubric, with the School's AI reading of the work beside you where it has one, and you attest that the mark is honest — the School relies on that, and the project line stays visible on the transcript. Lessons and tests are marked by the platform, not by you.

Expected study load

16 hours of lessons a week (4 hours a day, 4 days, short breaks included) plus 4 hours of project time — about 40 weeks for a full grade. The term is 12 months, so families can go slower. This is the School's own expected load, not a comparison with any public school.

Free tools, real projects

Lessons and projects use free, open-source tools families install themselves — Scratch and Python for programming; GNU Octave, Scilab, wxMaxima and R for maths and data; QScintilla for editing code; JupyterLab for notebooks — the same kinds of tools used in science, engineering and AI-assisted work. Grade 9–12 coding projects are read by the platform, never run on our systems, and marked by you with that reading beside you.

Optional beginner courses in Python, R, GNU Octave, Scilab, wxMaxima and QScintilla are planned, not yet available; today, lessons point to these tools where a task calls for them. See the full list by grade

One fee per grade

US$3,499 per grade for 12 months, plus tax where it applies; renews for the next grade until you cancel. Full refund within 14 days of paying if your child has studied 5 hours or less in that grade.

How registration works

A parent or guardian registers. Children do not sign up on their own, and registration opens grade by grade.

Create your parent account and confirm your email.
Add your child and choose a grade that is open for registration.
Read and accept the enrolment terms, including the subscription and renewal rules.
Your child signs in with their own username and password. No student email address is needed.

Results and moving up

The platform calculates each grade year's result from the student's coursework and released marks in the core courses; parents follow progress but do not assign grades, and can ask for a result to be reviewed. Moving to the next grade follows the enrolment terms you accept at registration, which set out early, regular and late promotion and what each costs.

A home-based learning option

Students learn online at home rather than at an in-person campus. There are no classmates, group chats or messaging between students on the platform, so there is no bullying or violence inside it; the lesson chat is monitored continuously and any child-safety concern goes to the school's safeguarding lead. Parents remain responsible for supervision and online safety outside the platform.

Course records show achievement in this school only. Admission, transfer credit and recognition elsewhere are decided by other schools and authorities, not by us.
