Why it matters
When a US team considers hiring from Latin America, the first worry is almost always language. Will the new hire understand a fast-moving call? Can they write a clear update to a client without help? Will an accent get in the way of trust? These are fair questions, and the honest answer is that the right person handles all of it well. The trick is reading the data correctly so you set your expectations on the candidate you will actually hire, not on a national average that includes everyone from schoolchildren to retirees.
Latin America is closer to the US than any other offshore region, not only in time zone but in business culture and communication style. The professionals who work remotely for US companies have usually spent years in English-heavy environments: international universities, global services firms, software teams, and customer support operations that serve North America. That background shows up in how they speak and write. The tool above ranks each market by its national EF EPI band so you can compare at a glance, and the sections below explain how to turn that signal into a confident hiring decision.
If time zone overlap is also on your mind, pair this guide with the time zone overlap calculator to see how many working hours line up with your team, and the hiring cost calculator to see what each market costs versus a US in-house hire.

The key insight
National EF EPI averages cover the entire tested adult population. The professionals available for offshore and nearshore roles, who are typically university-educated, urban, and working in tech, finance, or services, usually test one to two bands higher. LavaStaff screens every candidate's spoken and written English before you meet them, so the figure that matters is the candidate's level, not the country's average.
This is the single most important point on the page, so it is worth sitting with. A country index like the EF EPI samples a broad slice of adults learning English. It is a genuine measure, but it answers the question how good is English across this whole country, not how good is English among the software engineers, accountants, and support leads I would actually interview. Those two questions have very different answers. In most Latin America markets, the professional, urban, college-educated segment clusters at the top of the national distribution, often a full band or two above the headline number.
That is why a market can sit in the low band nationally and still be a great place to hire English-speaking staff. Mexico, Colombia, and Brazil all illustrate the point. Their national averages are modest, yet Mexico City, Medellin, Bogota, and Sao Paulo hold some of the largest pools of bilingual professionals in the hemisphere, built by years of global services work and software exports. When you select for the specific level a role needs, the country average stops being the ceiling and becomes a floor you have already cleared.
Levels
Strong business English is common. Candidates lead client calls, write clearly, and need little oversight on communication. A natural fit for customer-facing and senior roles.
Reliable working English for most professional tasks. Day-to-day work in English goes smoothly; confirm client-facing fluency per candidate during vetting.
The national average is lower, but the urban, university-educated pool you hire from runs well above it. Screen for the level the role needs and you will find strong bilingual candidates.
The EF EPI groups countries into proficiency bands that map loosely to the CEFR scale, the international standard for describing language ability from A1 for a beginner to C2 for a near-native speaker. For hiring, the levels that matter most are B1, B2, and C1. A B1 speaker handles routine professional tasks and clear written communication well. A B2 speaker is comfortable in meetings, negotiation, and detailed writing, which covers the large majority of client-facing roles. A C1 speaker operates with the ease of a fluent professional and rarely gives language a second thought.
Match the level to the role rather than overbuying. A back-office data or bookkeeping role runs smoothly with strong B1 to B2 English, since most of the communication is written and structured. A customer success manager, a sales development rep, or an executive assistant who fields live calls all day benefits from B2 to C1, where speed and nuance in conversation count. Knowing the target level keeps your search focused and your offer fair, and it makes the eventual shortlist easy to evaluate.
How to evaluate
A country ranking gets you to a shortlist of markets. Evaluating the individual gets you to a great hire. The most reliable signal is a real conversation. A short live call, ideally about the actual work, tells you more than any certificate, because you hear how the candidate listens, asks questions, and explains an idea under a little pressure. Pay attention to comprehension and clarity rather than accent. A clear, confident speaker with an accent communicates far better than a hesitant one without one.
Add a small written exercise that mirrors the role, such as drafting a customer reply, summarizing a meeting, or writing a short update. Written English is where a lot of remote work happens, and it is easy to assess fairly. If the role is heavily client-facing, run a brief role-play of a typical interaction. Certifications like TOEFL or IELTS and formal CEFR assessments can support the picture, but treat them as one input among several rather than the whole decision.
This is exactly the work LavaStaff does before you meet anyone. Every candidate's spoken and written English is screened during vetting, so the shortlist you receive already clears the bar for the role. You spend your interview time confirming fit and chemistry instead of testing basics, and you hire knowing the language question is answered.
Methodology
The rankings here track the EF English Proficiency Index, a widely cited global study of English skills among adult learners that groups countries into bands from Very High to Very Low. The relative order of Latin America markets is stable across recent editions: Argentina leads, a moderate cluster sits in the middle, and the largest markets average in the low band. The index scores shown are directional figures aligned with that banding so you can compare markets on one scale.
The CEFR levels are approximate mappings, not test results for any individual. The national CEFR column reflects the broad adult average for the market, while the talent pool column reflects the higher level the professional, urban segment typically reaches, which is the pool that staffing draws from. Both are planning signals to set expectations, not guarantees about a specific candidate.
Treat the whole comparison as a starting point. Language ability is individual, and the right way to confirm it is a conversation and a short writing sample tied to the role. The country data narrows your search and sets a sensible baseline; the candidate evaluation makes the decision. When you hire through a vetting-first model, that evaluation is done for you up front.
Questions
Yes, though the share of fluent English speakers varies a lot by country and, more importantly, by who you are hiring. National averages across Latin America land in the moderate to low bands on the EF English Proficiency Index, but those averages cover the entire adult population. The university-educated professionals who take offshore and nearshore roles, especially in tech, finance, customer support, and services, usually test one to two bands higher and work comfortably in English every day.
Argentina has ranked first in Latin America for English proficiency for years running, sitting in the high band. Costa Rica and Chile follow in the moderate band. Larger markets like Mexico, Colombia, and Brazil average lower nationally, but each holds a deep pool of bilingual professionals in its major cities, so they remain strong markets for hiring English-speaking talent.
For roles staffed with vetted professionals, a language barrier is rarely the problem people expect. The bigger risk is hiring on the country's national average instead of the individual candidate's tested level. When you screen for the English level the role actually needs, you find candidates who handle client calls, written work, and async collaboration well. Confirming spoken and written English during vetting matters far more than the country you pick.
The EF English Proficiency Index is a global ranking of English skills among adult learners, grouped into bands from Very High to Very Low that map loosely to CEFR levels. It is a useful directional signal for comparing markets, but it measures a broad population, not a hiring pool. Use the band to understand a market at a glance, then evaluate each candidate on their own merits.
The Very High and High bands map roughly to B2 and above, which is upper-intermediate to advanced and comfortable for most business work. The Moderate band sits around B1, solid working English. The Low band covers A2 to B1 on average, but the professional segment within those markets commonly reaches B2 and C1. For client-facing roles, aim for B2 or higher in the individual, regardless of the country's average.
Yes. Every candidate's spoken and written English is screened during vetting before you see a shortlist, so the level you care about is confirmed up front. That means you can hire from any market in this guide and still get the English level the role needs, because you are selecting on the candidate, not the national average.
