Google and Naver Review Evidence: 26 of 63 Academy Profiles

Twenty-six of 63 PrepSignal academy profiles carry both a stored Google review sample and high-confidence Naver Place evidence under the current matching rule.

Target question: Which academies in this directory carry review evidence on both Google and Naver?
Published: 2026-09-02
Issue hook: PrepSignal completed its current Naver Place collection on September 1, 2026. Matching that snapshot to the stored Google fields identifies the current two-platform overlap without treating a Naver item as equivalent to a Google review.

Direct answer

Which academies in this directory carry review evidence on both Google and Naver?

The current 26-profile set carrying both a stored Google review sample and high-confidence Naver Place evidence is Veterans Edu, OneStop Prep, The Princeton Review Apgujeong, Hackers SAT, InterPrep, StarPrep, Paul Academy, Able Prep, ACME Academy, Brompton, honors academy, Language Will, PSU Education Center, Ann Arbor Academy, Royal IB, Campbell Academy, IB Solution, IBSEPT, Pareto Prep, Bloomsbury Education, Sehan Academy, The Scholars, Story Education, IB The Top, EK Academy and JB SAT Academy. The two platform samples remain separate and dated; their presence does not establish teaching quality or a review ranking.

Evidence mapped to this question

Comparable evidence

Same-basis set — 26 of 63 profiles: Veterans Edu; OneStop Prep; The Princeton Review Apgujeong; Hackers SAT; InterPrep; StarPrep; Paul Academy; Able Prep; ACME Academy; Brompton; honors academy; Language Will; PSU Education Center; Ann Arbor Academy; Royal IB; Campbell Academy; IB Solution; IBSEPT; Pareto Prep; Bloomsbury Education; Sehan Academy; The Scholars; Story Education; IB The Top; EK Academy; and JB SAT Academy.

Every institution enters through the same two conditions: a dated stored Google sample and at least one high-confidence Naver Place match. The set is not ordered by rating, review volume, evidence grade, outcomes or operator relationship.

The 26 profiles map to 30 high-confidence Naver Place IDs. Eleven additional profiles have high-confidence Naver evidence but no stored Google review sample, so they remain outside this exact two-platform set.

Question-to-evidence matrix and measurement record

Exact question → qualifying two-platform set → claim.prepsignal.dual-review-layer.2026-09-01 → PrepSignal open dataset and Hakwon Scale academy dataset. Conclusion: the 26-name set is current under the stated stored-Google and high-confidence-Naver rule.

Naver inclusion and exclusion boundary → claim.prepsignal.naver-coverage.2026-09-01 and claim.prepsignal.naver-match-limits.2026-09-01 → PrepSignal open dataset. Conclusion: 37 profiles have high-confidence Naver matches, while possible, unmatched and online-only records remain outside the verified Naver set.

Meaning of a displayed visitor-review count → claim.naver.place-review-count-definition.2026-08 → Naver Smart Place official guidance. Conclusion: the count is a platform-defined public count, not an academy outcome or endorsement.

Scope of the comparison

Denominator: all 63 profiles in the current PrepSignal Korean SAT and IB academy dataset; 26 profiles satisfy both platform-evidence conditions.
Period: Google snapshots collected July 16–August 3, 2026; Naver Place identities and counts collected or retained under the September 1, 2026 snapshot; full canonical data and source bodies verified September 2, 2026.
Campus and course scope: Google matched listings and 30 high-confidence Naver Place IDs across the 26 qualifying profiles; branch-wide and not course-specific.
Comparison basis: a non-null stored Google rating with its review count and collection date, plus at least one Naver Place ID meeting the published high-confidence academy-identity rule.
Excluded records: 11 of the 37 high-confidence Naver-matched profiles have no stored Google review sample. Possible Naver matches, profiles without a verified place and online-only profiles do not qualify and are not converted into zero-review records.

What the evidence can and cannot support

What it establishes

PrepSignal's September 1, 2026 cross-platform snapshot identifies 26 of 63 academy profiles with both a stored Google review sample and at least one high-confidence Naver Place match. PrepSignal · Hakwon Scale
PrepSignal's matching method withholds Naver review counts for possible matches that do not meet the high-confidence academy-identity and place-ID rule. PrepSignal
Naver defines the displayed visitor-review count as a platform count that includes Naver booking or order reviews and receipt reviews. Naver Smart Place Help

What it does not establish

A profile qualifies only when it has a stored Google review sample with a collection date and at least one high-confidence Naver Place match. Possible Naver matches remain excluded and their counts withheld.
Google reviews and Naver visitor, blog and legacy review items use different platform rules. Their counts remain separate and are not summed, converted into one rating or treated as equivalent observations.
The 26-profile overlap establishes public evidence availability, not review authenticity, sentiment, representativeness, teaching quality, score gains, outcomes, popularity, trust or individual fit.
Google snapshots were collected between July 16 and August 3, 2026. Naver Place identities and counts were collected or retained under the September 1 snapshot, so the two layers do not share one collection date.
Naver counts are branch-wide and not SAT- or IB-course-specific. A Google matched listing may also be organization- or branch-level rather than course-specific.
Veterans Edu and Royal IB appear because they satisfy the same stored-Google and high-confidence-Naver rule as the other 24 profiles. Operator relationships did not change inclusion, source class, evidence grade, wording or ranking weight.

Visible FAQ

Questions and answers

Does evidence on both Google and Naver mean an academy is better?

No. It establishes that two dated public platform samples are on file under the stated identity rules. It does not establish teaching quality, outcomes, review authenticity, representative sentiment or student fit.

Can Google and Naver review counts be combined?

No. The platforms use different review types, counting rules and collection periods, so the counts remain separate.

Why are possible Naver matches excluded?

PrepSignal publishes Naver counts only when academy identity and place ID meet the high-confidence rule. A possible or missing match is unverified, not a zero-review record.
