Most school websites won't tell you their class size. They'll say "small classes" or "personalised attention" — those phrases are unregulated and mean whatever the marketing team wants. The number that is regulated, because KHDA collects it, is the school's student-to-teacher ratio: total enrolled students divided by total teaching staff.
It's not the same as your child's class size. A 12:1 student-teacher ratio at a school with lots of small-group support and specialist teachers can mean main-class sizes of 22 or more. But it's the most consistent, comparable signal across 226 schools — so it's what we'll use.
We have student-to-teacher ratios for 195 of Dubai's 226 KHDA-inspected schools. The remaining 31 don't publish complete staffing data. Here's what the 195 show.
The headline numbers
Across all 195 schools, the median student-to-teacher ratio is 13.2. The middle 50% of schools sit between 11.2 and 15.9. The smallest is 4.5 (Al Ghaf Private School). The largest is 24.6 (Himayah Kindergarten — Karama). That's a 5x range across schools that all sit on the same KHDA inspection regime.
How Dubai's 195 schools distribute on student-to-teacher ratio
Share of schools in each ratio band.

Fee tier predicts class size. Rating does not.
Two correlations, both calculated across the same 195 schools:
- Fee ↔ student-teacher ratio: Pearson r = −0.48 (moderate, negative — higher fee, smaller class)
- KHDA rating ↔ student-teacher ratio: Pearson r = −0.12 (very weak)
Translation: the price you pay is roughly four times more predictive of how many kids share a teacher than the school's KHDA rating. An Outstanding-rated school does not, on average, give your child a smaller class than a Good-rated school. A premium-fee school almost always does.
Median student-to-teacher ratio by fee tier
A clean ladder from Budget (under AED 20K/yr) to Elite (AED 80K+).
Median ratio in each band. Going from Budget to Elite cuts the ratio by nearly a third — roughly four fewer students per teacher.
Median student-to-teacher ratio by KHDA rating
Outstanding schools are not, on average, providing smaller classes than Good schools.
The line from Outstanding to Acceptable barely moves. Whatever drives KHDA's rating decisions, it isn't headcount per teacher.
By curriculum: a four-point gap from IB to Indian
The curriculum split is striking. IB schools run roughly six fewer students per teacher than Indian-curriculum schools — a structural difference that mirrors fee differences (IB schools cluster in the premium and luxury bands, Indian schools cluster in budget).
Median student-to-teacher ratio by curriculum
Curricula with at least 5 schools.
If you're choosing between curricula and class size matters to you, IB and American schools tend to deliver smaller ratios — but you're paying for it.
The 10 smallest student-teacher ratios in Dubai
Some are tiny niche schools (Japanese, Chinese), some are premium international schools where small classes are the product, and one or two are KHDA-Acceptable schools that simply have low enrollment.
| School | Curriculum | KHDA | Avg fee | Ratio |
|---|---|---|---|---|
| Al Ghaf Private School | UK | Acceptable | AED 45K | 4.5:1 |
| Al Adab Iranian Private School (Boys) | IB | Good | AED 14K | 5.7:1 |
| Japanese School | Japanese | Acceptable | AED 35K | 6.7:1 |
| Chinese School Dubai | Other | Good | AED 30K | 6.9:1 |
| Vernus International Primary | US | Acceptable | AED 39K | 7.4:1 |
| Clarion School | US | Good | AED 68K | 7.5:1 |
| Dunecrest American School | US | Good | AED 73K | 7.8:1 |
| Sheikh Rashid Bin Saeed Islamic Institute | MOE | Good | AED 8K | 7.9:1 |
| Dwight School | IB | Very Good | AED 88K | 8.2:1 |
| Dubai Heights Academy | UK | Very Good | AED 70K | 8.6:1 |
A small ratio at an Acceptable-rated school is usually a symptom of empty classrooms (low demand → fewer students → ratio drops without staff cuts). It's not the same thing as a small ratio at a Very Good-rated school running at capacity.
The 10 largest student-teacher ratios
The other end of the distribution is dominated by Indian-curriculum schools (which historically operate at scale on tight fees) and a couple of MOE and Philippine schools. Several of these schools are KHDA-rated Good or Very Good — high ratios are not, by themselves, a quality signal.
| School | Curriculum | KHDA | Avg fee | Ratio |
|---|---|---|---|---|
| Himayah Kindergarten — Karama | MOE | Good | AED 8K | 24.6:1 |
| United International Private School | Philippine | Acceptable | AED 9K | 23.7:1 |
| GEMS Legacy School | Indian | Good | AED 14K | 23.5:1 |
| The Philippine School | Philippine | Acceptable | AED 11K | 23.5:1 |
| Elite English School | Indian | Acceptable | AED 8K | 22.7:1 |
| GEMS Our Own English High School | Indian | Very Good | AED 13K | 22.4:1 |
| The International School of Choueifat (Br) | UK | Acceptable | AED 38K | 21.7:1 |
| Our Own High School (Branch) | Indian | Good | AED 12K | 21.6:1 |
| GEMS Our Own Indian School | Indian | Very Good | AED 11K | 21.4:1 |
| The National Charity School for Boys | MOE | Acceptable | AED 7K | 20.9:1 |
GEMS Our Own English High School is interesting — KHDA Very Good with 22.4 students per teacher. It's a clear case where the institution gets quality outcomes despite operating at scale.
What this means if you're choosing a school
- Don't infer class size from KHDA rating. Two Outstanding schools can have very different ratios. You have to ask, and you should ask in writing.
- Ask for actual class sizes, not the school-wide ratio. The ratio includes specialist teachers, learning support, ESL — your child's main classroom may have many more pupils. A school with a 12:1 ratio and 24-pupil classes is using ~half its teachers in specialist roles. That's fine — but it's a different model than 12 in a class with one teacher.
- Class size matters most in early years. The case for small classes is strongest from FS/KG to roughly Year 4. Above that, teaching quality and curriculum matter more. If your child is past primary, don't pay a 30% fee premium for a 2-pupil ratio difference.
- Check the trend. A school whose ratio has crept up over the past 3-4 years (more students, same staff) is making a quiet quality trade-off. A school whose ratio has come down is investing.
- Teaching assistants count. Some Dubai schools list 100+ teachers and 60+ teaching assistants; others have almost no TAs. The headline ratio doesn't include TAs but the in-class experience reflects them. Search for any school to see both numbers.
Methodology
Source: each school's most recent KHDA staffing return, as published on khda.gov.ae. Student-to-teacher ratio is reported by the school directly, not derived; we cross-checked against (students ÷ teachers) and used the school-reported figure where it differed by less than 5%. 31 schools were excluded for incomplete or inconsistent staffing data. Fee tiers use average annual fee across all year groups: Budget < AED 20K, Mid 20-40K, Premium 40-60K, Luxury 60-80K, Elite 80K+. KHDA rating is the most recent published cycle.
