Even K-pop Idols Went to Hagwon: Korea's Strangest Private-Tutoring Niche

It’s 10 p.m. in Daechi-dong, Seoul, and kids are pouring out of a building. It’s a math hagwon. At the same moment, outside another building in front of Yeoksam Station, more kids are pouring out. This one is a K-pop audition academy.

From outside Korea, K-pop shows you the finished stage — and maybe the word “trainee.” But ask what comes before becoming a trainee, and most people draw a blank. The answer is surprisingly ordinary. They go to hagwon. In Korea, becoming an idol is partly a question of talent, but before that it’s a story about private tutoring.

Do Korean parents really pay hagwon fees for K-pop, too?

They do. And that spending quietly disappears into a statistical line item called “arts-and-physical private tutoring.”

According to the 2025 Private Tutoring Survey released in March 2026 by Korea’s national data agency and the Ministry of Education, total private-tutoring spending hit ₩27.5 trillion, with 75.7% of students participating — three out of four kids pay to learn outside school. Asked why they take arts-and-physical lessons, 63.2% said “hobby, general education, or talent development” — comfortably the top answer. The statistics stop there, but that “talent development” bucket is exactly where an aspiring idol’s vocal, dance, and acting lessons live.

Four hours from Geoje to Busan: the case of RESCENE's Won-i

In July 2026, the fifth-generation girl group RESCENE reached the top in a strange way. Their song “LOVE ATTACK,” released in August 2024, hit No. 1 on Melon’s Top 100 a full two years after release. The trigger wasn’t an album or a TV appearance — it was member Won-i introducing her hometown of Geoje in a YouTube video. Her agency, The Muse Entertainment, was reportedly valued at roughly ₩60 billion after its value doubled in four months.

After the reversal, what started recirculating online was Won-i’s pre-debut academy footage, filmed at a Busan audition academy. Geoje, her hometown, had no academy for K-pop auditions, so she went back and forth to Busan to train. On Mudoctor Academy’s official “debut idols” page for 2024, you’ll find “RESCENE Won-i / The Muse Entertainment” listed as is.

This is the part that rarely lands with outsiders. K-pop private tutoring isn’t just a Gangnam story — it’s also a story about kids in the provinces commuting to bigger cities. And that commuting demand shaped the industry’s map. It’s no accident that Mudoctor’s branches in Busan, Daegu, Daejeon, and Ilsan are all inside Lotte Department Stores: a safe building at a transit hub, somewhere a teenager can go weekly with parental consent. A department store checks every box.

Which idols came out of these academies?

“I went to hagwon and became an idol” is a common résumé line in Korea. Just look at the rosters two major academies publish.

Notice how city names like Gwangju, Daejeon, Mokpo, Suncheon, and Busan keep showing up. The stage for K-pop private tutoring is not just Gangnam.

What exactly are these academies selling?

When Korean parents pay for an idol academy, they aren’t buying a “debut.” That’s not something an academy can promise. What it sells is two things: training and audition access.

The second is the whole point. The academy brings agencies inside its walls. Mudoctor advertises 8–10 in-house auditions a month and a 75-agency joint audition (“All-in-One Casting”); Joy Dance claims 250+ auditions a year. The difference between submitting an online application alone and having an SM, Starship, or RBW casting director sitting in your practice room — that’s effectively what parents are paying for.

After the hagwon: arts high school, then trainee

K-pop private tutoring has stages. If the academy is the entrance, the next gate is an arts high school. The practical dance and practical music departments at Seoul Performing Arts High School and Hanlim Multi Art School are the classic pipeline for aspiring idols — and to get in, kids attend yet another exam-prep hagwon. One hagwon begets another.

Here’s the key fact: parents only pay for stages 1–3. The moment a trainee signs with an agency at stage 4, the company generally covers training costs, which are later recouped through settlement. So the window where parents open their wallets isn’t the years after debut — it’s the years spent becoming a trainee. And no one publishes the pass rate for that window. Academies advertise their acceptance counts, but never their applicant counts.

Can foreigners attend these academies?

Yes, and they do.

• Mudoctor runs global classes and a Jakarta center.
• Joy Dance has opened direct-run branches in Tokyo (Daikanyama) and Osaka (Shinsaibashi), and reviews of its Korean branches mention students from Japan, China, and Canada.
• A large share of the 2026 names on Joy Dance’s debut roster are Japanese (tied to PRODUCE 101 JAPAN).

K-pop academies have become an export item of Korean private tutoring. The culture of Korean parents sending kids to hagwon to become idols is being replicated wholesale in Tokyo and Jakarta.

So is this a story about talent, or about money?

Both. And even Koreans don’t have a settled answer to the question.

On one side, idol private tutoring looks like a ladder for upward mobility. You’re judged on skill, not exam scores, and J-Hope came out of a Gwangju academy and Won-i out of a Busan one. On the other side, it looks like private tutoring expanding its reach — not satisfied with Korean, math, and English, now you have to pay for dance and singing too, and whether you live in a city with an academy again decides your opportunities. If Geoje had had an academy, Won-i wouldn’t have spent four hours on the road.

One thing is certain. From outside Korea, what you see in a K-pop idol is “natural-born talent.” From inside, what you see is a family that burned several years of hagwon fees and commuting time on that talent. Behind three minutes on stage, there’s usually a family.
