What Makes a Good English Teacher in Korea?

Ask a Korean hagwon director, a public-school principal, and an international-school head what makes a “good” native English teacher and you will get three different answers. But look closely and the same handful of things keep coming up, and almost none of them is “is a native speaker.” Being a native speaker is how you qualify for the visa, not how you get hired, and certainly not how you get asked back for a second year.

This guide walks through what Korean institutions actually weigh, from the legal floor everyone shares to the specific rubric a public school uses to decide whether to renew your contract. If you are planning to teach in Korea, or you are already here and want to be the teacher your school keeps, this is the bar you are being measured against.

First, the floor: the qualifications that get you in the door

Before anyone judges whether you are a good teacher, you have to be an eligible one. For English instruction, that means the E-2 (Foreign Language Instructor) visa, which the Ministry of Justice issues to teach conversation at one named employer, for up to two years at a time [source: hikorea.go.kr]. The E-2 comes in two flavors that map to where you work: E-2-1 for private academies (hagwons and English kindergartens) and E-2-2 for a contract with a provincial or metropolitan Office of Education, which is the EPIK / public-school route.

On top of the visa, the baseline requirements are consistent, and EPIK's official documents guide spells them out [source: epik.go.kr]:

• Citizenship of one of seven countries: the United States, Canada, the United Kingdom, Ireland, Australia, New Zealand, or South Africa. There is no eighth country.
• A completed bachelor's degree in any field. For EPIK, the diploma must be from an accredited university in one of those designated countries, submitted apostilled with sealed transcripts.
• A national-level criminal record check (FBI, RCMP, ACRO/DBS, and so on), federally apostilled and dated within six months of your contract start. Sub-national checks are rejected.
• A TEFL/TESOL/CELTA certificate of at least 100 real-time hours, which EPIK counts as its “Level 2” threshold. An education-related degree, a teaching license, a PGCE, or a B.Ed./M.Ed. exempts you. Note that 100 hours is the minimum, not 120, whatever a job ad says.
• A clean health and drug screen after arrival. This is a hard visa condition, not a preference.

Clear all of that and you are eligible. You are not yet “good.” The floor is the same for a first-year hagwon teacher and a veteran; what separates them is everything below.

What “good” actually looks like: a public school scores it

Here is the most useful fact in this article. In the public-school system, whether a native teacher is good enough to keep is settled by aformal evaluation with a rubric. The Ministry of Education's framework for native assistant teachers scores them across three domains, and a teacher generally needs to clear roughly 70 percent, per domain and overall, to be re-contracted [source: korea.kr]. The three domains are:

• Conduct and attendance (복무): showing up on time, following school rules, professionalism.
• Teaching practice (수업): the quality of your actual lessons, observed in class.
• Professional contribution and instruction, which explicitly folds in student satisfaction and your work supporting the English program.

Individual education offices publish their own version. Busan's 2026 native-teacher handbook, for example, weights conduct and attitude 40, lessons 30, and research and teaching ability 30, sets the renewal bar at 80 out of 100, and stresses that the score is cumulative, not one lucky observation, judged by your co-teacher, vice-principal, principal, and a district supervisor [source: pen.go.kr]. The same handbook lays out what good teaching looks like in plain terms: official work hours begin at 8:30 a.m., co-teaching meetings should be held at least a week in advance, and in class you should minimize teacher talk time, use clear instructions with comprehension checks, and keep students speaking.

The traits that show up in every study

Korean researchers have been asking students and teachers what makes a good native English teacher for years, and the answers are strikingly consistent. In one widely cited study of Korean students and teachers, the highest-rated qualities were fairness and no favoritism, creating a motivating classroom, respecting students' opinions, and giving individual attention, while teachers rated enthusiasm and a positive attitudenear the very top [source: kci.go.kr]. Other studies echo it: a survey of university students found most were satisfied with their native teachers and credited them especially with gains in speaking [source: kci.go.kr], and a large Seoul Office of Education survey found students were slightly more satisfied with native teachers than Korean ones, while parents and students alike said the ideal was a Korean teacher who both speaks English well and teaches well [source: hangyo.com]. (These are university and mixed-level studies, so read them as the shape of what Koreans value, not a hagwon parent survey.)

The most freeing finding is the one about native status itself. A peer-reviewed study of learners in Korea found only a weak statistical link between a teacher's native-speaker status and student outcomes: pedagogy and curriculum mattered more than where the teacher was born [source: eric.ed.gov]. In other words, your passport got you the interview. Your teaching is what makes you good.

What each type of school actually weights

“Good” is not identical across the four main employers. They all share the visa and background-check floor, but the emphasis, and the height of the bar, shifts as you move from private academies to international schools.

If you are weighing programs, our hagwon, public-school, and international-school pages break down each route in detail.

Co-teaching: the skill that makes or breaks a public-school teacher

In a Korean public school, a native teacher generally cannot run a regular class alone; you teach alongside a Korean English co-teacher, and that relationship is the single biggest predictor of how your year goes. Education-office handbooks describe good co-teaching as work that happens before, during, and after the lesson: co-plan ahead of the lesson, split roles clearly in class so students spend most of the time speaking, and debrief afterward [source: pen.go.kr]. Research on public-school programs reaches the same conclusion: effectiveness depends heavily on the native teacher and the Korean co-teacher working as a team. Teachers who treat the co-teacher as a partner (and, honestly, as the person who quietly scores them) thrive; teachers who see co-teaching as interference struggle. Our co-teacher relationship guide goes deeper on how to build that partnership.

International schools play a different game

If your goal is an international school, the definition of “good” changes. These schools hire on the E-7 professional visa, not the E-2, and screen much harder: a valid teaching license that matches your passport country, subject certification for secondary, typically a minimum of about two years of full-time experience at an accredited school, strong references including a current principal, and full safeguarding background checks, usually through recruiting platforms like Search Associates or Schrole [source: kis.or.kr]. For most people, the path is hagwon or EPIK first, build a track record and a credential, then move up.

The unglamorous trait that keeps you employed: reliability

Ask any Korean employer for their number-one operational concern and the answer is simple: whether you will show up, do the job, and finish the contract. Public schools bake this in: conduct and attendance is usually the largest single band on the renewal rubric, and repeated conduct violations can lead, through documented written warnings, to termination. Hagwons feel it even more acutely, because a teacher who leaves mid-contract means scrambling to cover classes and refunding parents. Reliability is what turns a one-year job into a renewed, better-paid second year.

How to become the teacher schools keep

None of this requires being a natural-born educator. It is mostly learnable and mostly about preparation:

Korvia has been placing teachers in Korean schools and academies since 2006, and our screening reflects exactly this list: a video interview with a native interviewer, a reference check, and a look at your teaching motivation, because a school's demo lesson and interview are where “good” is ultimately decided. If you are ready to find a placement that fits you, apply through Korvia and we will help you get there.

The bottom line

A good English teacher in Korea is made by the qualification floor everyone clears, then by teaching practice, reliability, and co-teaching, the exact things a public school puts a number on when it decides whether to keep you. Be measurable, be reliable, and be easy to work alongside, and you will get hired, and asked back for a second year.
