Among 1,806 foreign nationals who hold English teaching certificates, 532 teachers had teaching licenses from their countries, 1,134 had TESOL or TEFL and 140 had both.

There is a huge difference between TESOL/TEFL certificate holders and licensed teachers. The former qualification may be earned in as little as one month and even more rigorous programs like the Cambridge are focused on adult language acquisition. Licensed teachers, on the other hand, spent one semester in the classroom as a student teacher upon completion of 3-4 semesters of education coursework.

20년 전만 해도 국민의 영어 실력이 고민이었다. 하지만 영어 공교육을 강화하고 상당수 TV프로그램을 영어로 내보내는 등의 노력을 한 끝에 비영어권 국가 중에 영어가 잘 통하는 나라가 됐다.
From the Donga article:

Only 20 years ago [Finnish] people’s knowledge of English was worrisome. But after measures such as strengthening the public education of English and broadcasting a considerable part of TV programs in English, it became a non-English speaking country where English is spoken well. (Translation done with knowledge of English taught by non-native teachers.)

At least one fact is correct in this snippet, and it is that Finland is not an English-speaking country. Some might even say that English is spoken relatively well. But no remarkable changes have taken neither in the EFL education of English nor TV broadcasting.

The Kulosaari Secondary School where the Maeil Gyeongje reporter seems to have visited is not an ordinary school but specialized in English-language education. As far as I know, this kind of arrangements are mainly for expatriate residents; Finland is not really a favorite destination for the international bureaucratic (EU etc) or business elite, so the authorities are doing their best in the school front to entice this kind of expertise here.
From Maeil Gyeongje:

As the competition [for teacher education] is high, the demands are also many. To become a middle or high school teacher, master’s degree and a 3-month practise in an English-speaking country are required.

A 3-month practise in an English-speaking country may be required in the Kulosaari school, but definitely not in general. (Teacher practise can be done abroad.)

And all the Koreans would need to do was to have less crappy Korean dramas in TV and have instead more crappy English-language dramas instead, and give boot to voice actors except children’s programs.

The sweet irony of having members of the anti-foreigner teachers union being replaced by Korean kids straight out of high school.
