Argentina ranks #1 in English proficiency in all of Latin America — every single year on the EF English Proficiency Index.
That’s not an opinion. That’s data.
And if you’re hiring remote workers in Latin America, or you’re a LatAm professional trying to land clients in the US, UK, or Australia — that ranking matters more than you probably realize.
Because English isn’t just a skill here. It’s the difference between getting hired and getting passed over. Between a client relationship that runs smoothly and one that slowly falls apart over miscommunication.
Let’s get into the actual numbers.
English Proficiency Rankings in Latin America by Country
The EF EPI ranks countries annually by English ability. In Latin America, the gap between top and bottom isn’t small — it’s significant.
Here’s where things actually stand:
Argentina — Top of the region. Buenos Aires specifically rivals some European cities. Near-fluent English is common among professionals, especially in tech, marketing, and management.
Uruguay — Strong and underrated. Montevideo has a dense concentration of bilingual talent in full-stack development, DevOps, and support roles.
Costa Rica — High proficiency, and arguably the most US-aligned workforce in the region. Decades of BPO and customer service work for American companies has shaped how professionals here communicate. They know the cadence.
Chile — Moderate overall, but improving faster than most. Santiago and the surrounding tech corridor are the most English-proficient zones. The trajectory here is genuinely upward.
Colombia — Medellín and Bogotá have real, functioning tech hubs. English among that cohort is solid. Outside those cities, it thins out. Expect strong technical English, lighter conversational English.
Mexico — Enormous talent pool, uneven proficiency. Younger urban professionals often have strong English. But “large pool” also means “wide variance.” You have to screen carefully.
Brazil — Same story at a larger scale. Bilingual talent exists and it’s exceptional. You just have to find it.
Peru, Bolivia, Paraguay, parts of Central America — Technical talent is real here. English is lighter, especially outside major urban centers.
How to Match English Requirements to the Right Remote Role
Most hiring guides treat English like a binary. You either have it or you don’t.
That’s lazy thinking and it costs employers good talent. Here’s how to actually think about it:
Client-facing roles — sales, account management, customer support, product managers talking to external stakeholders — these need B2 or higher. Real fluency.
Technical roles — developers, data analysts, QA engineers, back-end engineers — these typically need what you’d call “technical English.”
This one distinction reshapes your entire country strategy.
For fully client-facing roles: Argentina, Uruguay, Costa Rica. English feels natural. Integration into Anglophone teams is smooth. Rate expectations are usually higher but the communication overhead is lower.
For technical roles: Colombia, Chile, Peru. Pair them with a bilingual PM or project lead, and the English friction disappears entirely. The output quality is excellent.
Multiple employer guides focused on US/UK/AU hiring explicitly recommend this approach — screen by role requirement first, then narrow by country. Not the other way around.
How Latin American Remote Workers Improve Their English for US Clients
This part doesn’t get written about enough.
The LatAm professionals consistently landing US and UK clients aren’t waiting for their English to be perfect. They’re strategic about it.
They define a target level before they practice. Not “improve my English” that’s too vague. B2 to run comfortable Zoom calls. C1 for account management or client presentations. Knowing the target shapes the training.
Thirty minutes a day beats weekend cramming. Podcasts, tech blogs in English, shadowing repeating aloud what they hear in videos or meetings. Every day. That consistency is what actually moves the needle.
They join English-only online spaces. Freelancers from Colombia, Mexico, and Brazil report that English-only Slack groups, Discord servers, and remote-work communities build fluency faster than any classroom.
They start with technical roles on purpose. A lot of successful LatAm remote workers deliberately target back-end or infrastructure work first — where code and tickets matter more than smooth speech then move into higher-visibility roles as their English improves. Smart sequencing.
They learn business English, not just conversational English. There’s a difference. “I’m blocked until I get X from your side.” “Here’s my proposed next step.” “Here’s a status update on what shipped this week.” These phrases are currency in remote teams.
Many of the most successful remote workers from Argentina, Colombia, and Costa Rica explicitly say they hit at least B2 before targeting US clients. Not because someone told them to — because they saw what happened to people who didn’t.
How to Test English Proficiency When Hiring Remote Workers
Run a live interview for client-facing roles. Ask scenario questions that answer tells you more than any written test or self-reported proficiency level.
For technical roles, a writing test does the job. Ask for a short status update or a bug report. You’re looking for clarity, not perfect grammar.
If you can read it and understand exactly what they’re saying — that’s a pass.
If a candidate has a formal certification on their profile, that does a lot of the work for you. Here’s what to look for:
- Cambridge C1 Advanced (CAE) — formally aligned to C1, widely recognized by US/UK/AU employers. If they have this, the English question is largely settled for client-facing roles.
- IELTS 7.0 or higher — band scores of 7.0 to 9.0 map to C1–C2 equivalent. Strong signal for any communication-heavy role.
- TOEFL iBT 100+ — scores between 100 and 120 land in the same C1–C2 range. Available online, so common among remote workers across the region.
You don’t need to run an elaborate test if one of these is on their profile. Just have a short conversation to confirm it translates to their actual communication style.
No certification? That’s fine too — plenty of excellent remote workers haven’t sat a formal exam. But it means your screening process needs to do more of the heavy lifting.
How English Proficiency in Latin America Is Changing
The talent in Latin America is real. The English question is manageable.
Know what your role needs, match your geography to that requirement, and don’t treat the whole continent like one homogeneous market.
It isn’t.
