Non-native speakers, how common is English as a Medium of Instruction (EMI) in your countries?

In Italy, Italian is the default language in all levels of education. You can learn English as a second language in secondary schools and, more recently, in some primary schools but not all, and that's a shame because considering how ubiquitous English is nowadays, as you rightfully said, the earlier you start learning it, the better.

In Türkiye, Turkish is primarily used as the medium of instruction in schools, except for a few university programs, schools that mainly serve minority groups, and some private institutions. Malaysia’s tertiary education system can be easily understood through [Kachru’s Three Circles of English Model](https://www.researchgate.net/figure/Kachrus-three-circles-model_fig1_282976715). Long story short, yes, it’s primarily a result of British colonialism.

I think you’re right that part of this is a vestige of colonial rule. I’m from Pakistan; English is the medium of instruction in all private schools and many public ones, and the lingua franca, Urdu, though spoken to varying degrees in homes, is taught in schools the way a second language is.

In my country it depends on the learning facility, but I've been learning English since kindergarten until my second year of uni. While not so ubiquitous in the lower and middle education, in terms of gathering knowledge, it was vastly present in the curriculum. During higher education, however I found myself sourcing knowledge from papers and/or websites written in English, mainly because of the nature of my studies (Computer Science). That said, the default language for teaching, writing reports and exams, as well as writing dissertations is my native language. This does not include writing articles for scientific journals, some of my professors have written articles both in English and in my native language.

german here. zero. everything is in german.

In Venezuela all levels of education are conducted in Spanish, and I think that applies to most if not all of LatAm, of course, unless you enroll your child in a bilingual school where the focus is on facilitating full immersion. Even still, I would say they are not as common and they are all private + I haven't heard of a "bilingual University" yet (yes, you can take foreign language classes but not a full program outside of majoring in modern languages, but again, most general subjects would be in Spanish even in that case)

A lot of European countries (Germany, Netherlands, Austria, Nordic countries) have English-speaking graduate programs. There are also some bachelor’s programs in English but they’re much less common.

In India, extremely common in the national boards of education. In state boards, I'd say it's uncommon. In higher levels of education, it's almost entirely in English, including teaching, research and publications.

Canada: francophone universities use textbooks in graduate classes in whichever language they are written, which is often English Ditto the Netherlands and Israel

I'm in the Netherlands. In higher education, it's very common. A good chunk of our research university programs are in English, maybe a third? Maybe a bit more. Many programs that are primarily in Dutch require a good understanding of English regardless because much of the scientific literature is in English, and there may still be some courses that are taught in English. Most applied science universities also offer some majors in English, though I believe this is less common. I'm not sure about trade school/vocational education. Some secondary schools offer bilingual programs at the two longest programs (preparatory for applied science (5 years)/research uni (6 years)). Not all do, and I believe it's more common for the 6 year program to have it, but it means in the first three years at least 60% of classes are taught in English, and at least the 6 year program also takes IB HL English Language and Literature alongside the regular secondary school curriculum. I don't have experience with the 5 year program so I can't speak on it. We also have some international and British schools, both primary and secondary. Not sure how many to be honest. ETA: English is commonly already taught as a second language in primary schools, but aside from international schools, the language of instruction in primary school is Dutch.

It’s due to colonialism. My parents grew up in Malaysia during the period where they had to learn English. So their Malay and Chinese isn’t actually that good.

My stepmum is Malaysian (in her ~~60s~~ edit actually must be in her 70s) and when she grew up all education was in English, definitely a remnant of our colonialism, yes. She actually didn't agree with the fact my brother and sister were taught in Malay in school, feeling like her native English made it much easier for her to get around in the world, so yes I'd imagine that's why the highest level of education still sticks with English. At a base level it's true that your native language should be the main language but I'd guess that English has become such a de facto universal language, particularly in academia, that it's maybe larger than colonial concerns to consider its use. (As a physicist and music fan I am intrigued to find a completely new use of 'EMI'.)

Not in Ukraine. I've been to Malaysia and I was surprised how proficient everyone is in English. In Ukraine we (or rather they, since I emigrated) struggle to impose English even among police. It could be due to the fact that Russian was *the* lingua franca.

Born in West Germany, live in the US.  English is pretty common here. 

The Philippines is probably the only country in Asia where English is taught from pre-school to college. Though subjects tend to be taught in a mix of English and Filipino, most textbooks are in English so teachers tend to default to that esp in private schools.
