Key figures

  • 11 academy profiles cover the Jeju Global Education City area — 6 SAT and 5 IB (dataset updated July 18, 2026).
  • The July 20 Jeju report recorded 351 Google reviews across 5 confirmed listings, including 24 for Royal IB. The August 3 recheck recorded Royal IB at 63, a 39-review increase; applying that dated change to the same five-listing baseline yields the current 390-review sample. Only 2 profiles hold 10 or more reviews — 314 (4.9/5) at Veterans Edu (V1 cross-verified) and 63 (5.0/5) at Royal IB (V2 multi-source).
  • All 6 Jeju-only academies carry V4 self-published or V5 limited-public-data grades; the area has no V3 platform-verified profile.

What 11 academy profiles show

The verification-grade split follows campus structure. The only V1 and V2 profiles in the area operate dual Seoul–Jeju campuses, and both also run live online classes. The 6 academies operating only in Jeju have no press-checked or platform-verified data yet, so their program claims remain self-published.

The review sample is thin and concentrated. Of 390 tracked Google reviews, 314 sit in a single listing, and 6 of the 11 profiles show no confirmed Google review data at all. In this area, rating comparison is not statistically meaningful; review counts work only as sample-size signals.

Timing matters for families planning around the August school-year start at KIS, NLCS, BHA and SJA (exact dates per each school's notice). July and early August are peak enrollment weeks in the area. Families relocating from US time zones can start with the live online options at the two dual-campus profiles and confirm in-person schedules after arrival.

Scope of the comparison

  • The note covers 11 Jeju Global Education City profiles: 6 SAT and 5 IB, using the dataset updated July 18, 2026.
  • The Google review sample totals 390 reviews across 5 confirmed listings after applying the August 3 Royal IB recheck to the July 20 Jeju baseline; 6 profiles have no confirmed Google review data.
  • The 314-review count is concentrated in one representative listing, and the V1/V2 records describe dual Seoul–Jeju organizations rather than Jeju-only teaching cohorts.

What the evidence can and cannot support

What it establishes

11 academy profiles cover the Jeju Global Education City area — 6 SAT and 5 IB (dataset updated July 18, 2026).

What it does not establish

  • A V4 grade means the figures are self-published; ask each academy for written, dated documentation before comparing programs.
  • Treat review counts as sample size, not quality. Below roughly 10 reviews, a 5.0 average and a 4.0 average are not distinguishable signals.
  • For dual-campus academies, ask separately about resident Jeju teaching staff versus Seoul-based support, and check whether live online sections are verified against your time zone before enrolling.
