Colegio Bonsai Montessori offers a 100% Montessori-inspired online school with preparation aimed at MINEDUC free exams. With live Zoom classes of about 2 hours daily Monday–Thursday, it differs from full-morning live schools like Online College Chile or Colegio Virtual de Chile. This article summarizes what Chilean families can evaluate.
The offer revolves precisely around free exams: subjects focus on what MINEDUC tests. To understand the official process, see our guide to free exams and the deadlines published on Ayuda MINEDUC.

Who they are and background
Bonsai Montessori presents as an online school inspired by Montessori and adapted to remote format. They report 1,000+ linked families and require a minimum of 10 students to open a course. The offer combines Montessori-inspired messaging — respectful pace, guided autonomy — with explicit focus on subjects tested in free exams. Support materials are not shipped ready-made: they come as printable cut-out PDFs to assemble at home.
Methodology and how learning works
Live Zoom classes run about 2 hours daily Monday–Thursday, focused on subjects relevant to MINEDUC free exams. They complement with printable cut-out PDF materials, reinforcement and expansion activities, and periodic evaluations. The rest of the day is for autonomous work with family accompaniment.
Levels, schedule, and platform
They serve 1st basic through 4th secondary. English starts from 5th basic. For 2026, classes run March 9 – October 30, with office hours 09:30–13:30 Monday–Thursday. Always confirm the current calendar and enrollment conditions with admissions before enrolling.
MINEDUC validation and reported results
Bonsai aligns its content with free-exam tests, but — like every project of this type — does not issue ministry certification for attendance: the certificate comes from passing the official sitting, which families register for themselves. If the school shares pass rates, treat them as institutional figures and ask how they are calculated.
Strengths
- Montessori online focus — differentiated pedagogy in the market.
- Moderate live day (~2 h): less screen than full-morning schools.
- Integrated PDF materials, reinforcement, expansion, and evaluations.
- Explicit prep oriented to MINEDUC free exams.
- English from 5th basic.
Best fit for which family
A good fit if you value the Montessori inspiration, want free-exam prep with fewer daily video hours, and can support autonomous study at home. Less ideal if you need 4-hour live days or traditional regular MINEDUC enrollment.
Practical tip: ask how many students are enrolled in your child's level (for the 10-student minimum), confirm the current calendar, and from March build an autonomous study plan complementing the 2 Zoom hours.
Cons to weigh
- They do not ship ready-made physical materials: support comes as printable cut-out PDFs for the family to assemble at home.
- Despite presenting itself as a Montessori school, it does not have Montessori Guides.
- Only 2 live hours, Monday–Thursday: the rest of learning depends heavily on home accompaniment.
- A course may not open if the 10-student minimum is not met.
