TL;DR: The Greenhills campus publishes three admission requirement sets — Casa, Grades 1 to 5, and Grades 6 to 11 — and nothing for Grade 12. From Grade 2 upward it applies a real academic cut-off: a quarterly general average of at least 80 percent with no grade below 78 percent in any academic subject or in deportment. Junior Casa entrants sit a one-week trial, not a test. Everything runs through the campus's own online portal. No tuition figure appears anywhere on the OBMC website, and rates differ between its five campuses, so Greenhills fees have to come from the Greenhills office.
Everything below comes from O.B. Montessori Center's own admission pages for the Greenhills campus. Where the school publishes nothing, this guide says so rather than filling the gap.
The structure you are applying into
OBMC organises the Greenhills campus, on Eisenhower Street in San Juan, into five bands: Casa (ages 3 to 5), Primary (Grades 1 to 3), Intermediate (Grades 4 to 6), Junior High School (Grades 7 to 10, ages 13 to 16), and Senior High School (Grades 11 and 12, ages 17 and 18).
Admission requirements do not follow those five bands. They follow three: Casa, Grades 1 to 5, and Grades 6 to 11. That mismatch matters when you are applying for Grade 6, because the requirement page treats it as a high-school-style application with recommendation forms, even though academically it sits in the Intermediate band.
The school's directory page covers the basics — address, contact, levels offered. This guide covers what happens after you decide to apply.
Casa: the age cut-off is a date, not an age
OBMC splits Casa into three entry points, each with an age requirement pegged to August 31 of the next academic year:
| Level | DepEd equivalent | Must be this old by Aug 31 |
|---|---|---|
| Junior Casa | Pre-Kindergarten 1 | 3 years old |
| Junior Advanced Casa | Pre-Kindergarten 2 | 4 years old |
| Advanced Casa | Kindergarten | 5 years old |
The date is the trap. A child who turns three in October is not eligible for Junior Casa that August, regardless of readiness. Work backwards from the birthday before you plan the year.
Junior Casa carries one condition the other levels do not: the child is required to undergo a one-week trial. OBMC does not publish what happens if the trial goes badly, or whether it is charged. Ask.
The document list, band by band
Three documents are common to every Filipino applicant at every level, all as scanned PDFs:
- Birth certificate authenticated by the Philippine Statistics Authority
- A recent passport-size photo (4.5 cm x 3.5 cm, or 1.8 in x 1.4 in)
- Report card (SF9), if applicable
That is the whole list for Casa. Grades 1 to 5 add academic conditions rather than paperwork. Grades 6 to 11 add three documents:
- A scanned copy of the current school's Government Recognition
- A completed recommendation form from the principal
- A completed recommendation form from the guidance officer
Both recommendation forms are described as school-to-school transactions. You are not filling them out, and you cannot rush them from your side. If you are applying in the middle of a school year, start those conversations with your current school before you touch the OBMC portal.
The academic rule most families miss
From Grade 2 upward, OBMC publishes a numeric standard: a quarterly general average of at least 80 percent, with no grade lower than 78 percent in any academic subject and in deportment.
Two things worth reading twice. First, it is a quarterly general average, not a year-end one, so a weak quarter counts. Second, deportment is named alongside academic subjects, which means conduct marks are part of the eligibility test, not a footnote.
OBMC does add a release valve: "Applicants with grades below the minimum requirements are welcome to apply. However, the application is subject to the approval of the Admissions Committee." So a 79 is not an automatic rejection — it is a discretionary case. Expect it to take longer and expect to be asked about it.
Grade 1 is handled differently. Applicants must be six by August 31, must have completed kindergarten at a DepEd-accredited school, and must already have been issued a Learner Reference Number. No grade threshold applies.
Grades 2 to 5 applicants must be seven to ten years old; Grades 6 to 11 applicants must be eleven to seventeen.
Foreign and dual-citizen applicants
OBMC publishes a separate stack for non-Filipino applicants, on top of the standard requirements:
- Birth certificate, with an English translation where applicable
- Passport, including the biodata page and visa status
- Alien Certificate of Registration (ACR) I-Card from the Bureau of Immigration
- Special Study Permit documentary requirements, which OBMC links directly to the Bureau of Immigration's own forms
Grades 6 to 11 foreign applicants have one more, and it is the slow one: original school records (report card and transcript) authenticated by the consular office in the country of origin. OBMC states plainly why — DepEd needs it to issue the Learner Reference Number. Consular authentication is measured in weeks, not days.
Dual citizens submit a valid Philippine passport plus either a Certificate of Recognition as a Filipino Citizen or an Identification Certificate as a Filipino.
How the application actually runs
The Greenhills Campus Admission page carries a Requirements dropdown with the three bands and an Apply Online button pointing at the campus's own portal. You complete the form there and upload the scanned PDFs.
The campus-specific detail matters. OBMC runs five campuses — Angeles, Fairview, Greenhills, Las Pinas and Sta. Ana — and each has its own admission page, its own requirements pages, and its own application link. Landing on the wrong one is easy and wastes a full upload cycle.
OBMC's closing note on all three requirement pages: "Submitted admission requirements are subject to evaluation before enrollment." Submitting is not enrolling.
For Greenhills specifically, the registrar's office publishes a landline (+632 8723 9060), three mobile numbers, and a dedicated address at [email protected]. Use the campus email, not the general one.
What OBMC does not publish
Say it plainly, because the gaps are large:
- No tuition or fees. Not for Greenhills, not for any campus, not at any level. OBMC's own directory note is that rates differ between campuses, so a figure someone quotes you for Fairview tells you nothing about Greenhills. Our OB Montessori tuition guide explains why unofficial figures circulate and what they are worth.
- No application deadline. The page says admissions are open for the academic year; it names no closing date.
- No entrance examination at any level. Only the Casa trial week and the Admissions Committee review are described.
- No Grade 12 entry route. Requirements stop at Grade 11.
- No class size, teacher-to-child ratio, or waiting-list policy.
Senior High School: one curriculum, not a strand menu
If you are applying for Grade 11, know this before you compare schools. OBMC describes its Senior High School curriculum as GAS Plus — a general academic programme designed, in its words, to let students explore career options and move on to any local or international college. It does not publish STEM, ABM, HUMSS or TVL strands as separate tracks.
That is a real fork in the road. A student already set on engineering or accountancy may want a school that runs a dedicated strand; a student still deciding is exactly who GAS Plus is built for. Our guide to SHS strands and job demand is worth reading alongside this decision.
What to ask on the campus visit
The published pages leave enough open that a visit is not optional. Bring these:
- What is the current schedule of fees for this level at this campus, and what does it include beyond tuition?
- Is the Casa trial week charged, and what happens if the child is not placed after it?
- Are you accepting Grade 12 transferees this cycle, and under what conditions?
- How long does Admissions Committee review take for an applicant below the 80 percent average?
- What is the actual class size at the level we are applying for?
- For foreign applicants: how far in advance do you need the consular-authenticated records to secure the LRN in time?
Who this school suits
A family that wants Montessori pedagogy through the elementary years and a DepEd-aligned high school after it, that can meet a genuine academic and conduct standard from Grade 2 onward, and that is comfortable asking for fee information rather than reading it online. If you want a school that publishes its numbers before you call, this is not that school. If you want the method and the campus network, the paperwork here is well documented — which is more than many private schools manage.
