You scored well enough on your TOEFL or IELTS to get admitted. You can read academic English. You can write a coherent paragraph. But you arrive in the US and realize within two weeks that what they tested you on and what you actually need to function here are not the same thing.
Lecture English is different from office hours English. Email English is different from meeting English. And none of them are the same as the casual conversational English you'll use with classmates, roommates, and eventually with colleagues.
This is the actual gap that English language programs in the US fill, if you pick the right one. If you pick the wrong one, you spend a semester in a classroom that reinforces what you already know, at significant cost.
Here's how to choose correctly.
The Types of English Programs: Which One You Actually Need
Not all English language courses are the same and conflating them leads to expensive mistakes.
Intensive English Programs (IEPs): Full-time English instruction programs, usually run by universities or established language schools. They cover grammar, academic writing, reading comprehension, speaking, and listening. Designed for students who need significant English improvement before entering a degree program. If your TOEFL score put you below the admission threshold and your university offered conditional admission pending IEP completion, this is what you're in.
Academic English for Graduate Students: Programs designed specifically for international graduate students who are already enrolled in a degree program but need academic writing support. These are typically offered through your university's writing center or as standalone courses. They focus on thesis writing, research paper structure, academic argumentation, and citation norms.
Conversation and Communication Courses: Programs that focus on spoken English, specifically US conversational norms, presentation skills, and professional communication. These are often overlooked by international students but address the gap that TOEFL tests don't: actual real-world communication fluency.
Online English Platforms: Duolingo English Test, Coursera English courses, LinkedIn Learning professional English content. Supplemental, not primary. These work best as ongoing practice alongside a formal program, not as standalone solutions.
Top University-Based IEP Programs Worth Knowing
University-based Intensive English Programs are generally the most academically rigorous and the most recognized by other universities when it comes to transfer of conditional admission status. Here are categories of programs with strong reputations:
Research university IEPs: Programs at large public research universities (think Big Ten schools, flagship state universities) tend to have strong academic writing components and direct pathways into degree programs. They're also often less expensive than standalone language schools because they're partially subsidized by the university.
Community college ESL programs: Significantly lower cost than private language schools, often with strong community integration components, and typically available to anyone with appropriate visa status. For students on a budget who need foundational English improvement, community college ESL programs are underutilized.
Private language schools with university partnerships: Schools like ELS Language Centers, Kaplan International, and American English Institute operate on or near university campuses and have conditional admission agreements with partner universities. If your plan is to enter a specific partner university after completing the program, verify the agreement directly with both institutions before enrolling.
The Duolingo English Test: What It's Actually Good For
The Duolingo English Test (DET) is now accepted by over 5,000 institutions globally, including many US universities. It's taken online, costs $65, and returns results in 48 hours.
For many international students, the DET is the most accessible English proficiency credential available. Unlike the TOEFL ($200+) or IELTS ($250+), the DET's cost and accessibility make it viable for students who need to demonstrate proficiency quickly or who missed a testing window.
The limitation: it is not accepted everywhere, and some programs specifically require TOEFL or IELTS. Verify acceptance before taking the DET as your primary credential.
As a self-study tool, the DET preparation materials on the official site are also genuinely useful for practicing academic English listening and speaking in a low-stakes format.
What Nobody Tells You About English Language Programs in the US
The academic writing gap is different from the speaking gap. Most international students underestimate how much US academic writing is about structure, argumentation, and citation conventions rather than just correct grammar. A strong academic English program will teach you how to make an argument in a way that a US professor expects, which is different from how academic writing works in many other educational systems.
Your campus writing center is free and underused. Every US university has a writing center. Most international students never visit it. This is an extraordinary waste of a resource. Writing center consultants read your draft, discuss your argument, and help you strengthen it, free, multiple times per semester. One writing center session per paper is a meaningful grade improvement for most international students. Make it a habit from Week 1.
American conversational English is full of idioms that nobody explains. "Touch base," "circle back," "take this offline," "low-hanging fruit," "move the needle." These are everywhere in American professional and campus culture. They won't come up in an academic English class. Exposure comes from actual interaction, campus club participation, and consuming American media.
Grammarly is not a substitute for understanding. Use Grammarly (the free version works for catching errors, the premium version helps with academic tone) as a tool for catching errors after you've written, not as a crutch that replaces the actual writing process. Students who over-rely on Grammarly improve their submitted writing but don't improve their underlying ability.
Before vs. After: What Targeted English Practice Actually Changes
A graduate student from Japan I worked with had passed her TOEFL with a sufficient score for admission but struggled in seminars. She could understand lectures but froze in the back-and-forth of discussion-based classes and found herself staying silent through entire seminar sessions. Her participation grade was suffering.
She spent six weeks using one specific tool daily: 30 minutes of shadowing (listening to a recording of academic English speech and speaking along with it in real time) combined with one office hours visit per week where she practiced speaking in English with her professor rather than emailing.
By Week 10 of the same semester, she was participating regularly in her seminar. By the following semester, two professors had noted her communication improvement in academic references. The gap wasn't ability. It was practice and exposure in the specific context where she needed to perform.
Specific Skills to Build, With the Best Resources for Each
Academic writing: Your campus writing center plus the Purdue Online Writing Lab (OWL) at owl.purdue.edu. This is the most comprehensive free resource for US academic writing norms available online. Use it constantly.
Academic vocabulary: The Academic Word List (AWL) is a research-backed list of the 570 most common academic English words. Flashcard apps like Anki with AWL decks are a highly efficient way to close vocabulary gaps specifically relevant to academic reading and writing.
Listening and comprehension: TED Talks at a variety of academic levels, podcast lectures from university lecture series (MIT OpenCourseWare has recorded lectures), and NPR (National Public Radio) for general American English listening practice at a literate, educated conversational register.
Speaking and pronunciation: The shadowing method (described above) plus participation in campus conversation exchange programs. Most universities offer conversation partner programs that match international students with native English-speaking students for practice. These are free and consistently underused.
Professional communication: LinkedIn Learning has solid courses on professional email writing, US meeting culture, and presentation skills that are specifically applicable to a US workplace context. Many universities provide free LinkedIn Learning access through the library.
Your English Improvement Action Checklist

- [ ] Set up a Grammarly account (free tier is sufficient to start) and run it on every email you send to professors
- [ ] Add 30 minutes of English listening practice to your daily schedule (TED Talks, NPR, university podcast lectures)
- [ ] If you need formal English certification, compare TOEFL, IELTS, and Duolingo English Test acceptance at your target institution before registering
- [ ] Find out whether your campus offers specific academic English courses for graduate students and whether they count toward your credit requirements
The Real Point
Your English is already good enough to be here. The question is whether it's specifically calibrated for the US academic and professional contexts where it matters. Those are learnable skills, not fixed traits.
The students who improve fastest in the US are not the ones who arrived with the highest TOEFL scores. They're the ones who treat English improvement as an ongoing practice rather than a credential already obtained. Every office hours visit, every writing center session, every conversation with a classmate who speaks differently from you, it compounds.
Six months from now, the gap between where you are and where you could be is determined almost entirely by how deliberately you practice in the specific contexts where you need to perform.
Frequently Asked Questions
What is the best English language program for international students in the US?
The best program depends on your specific gap. If you need significant foundational improvement before entering a degree program, a university-affiliated Intensive English Program (IEP) at a large research university or accredited language school is the most effective. If you're already enrolled in a degree program and need academic writing improvement, your campus writing center combined with a graduate academic writing course is the highest-ROI option. If you need professional and conversational English specifically, campus conversation exchange programs and LinkedIn Learning professional communication courses address that gap directly.
Is the Duolingo English Test accepted by US universities?
Yes, over 5,000 institutions globally now accept the Duolingo English Test, including many US universities. It costs $65 and returns results in 48 hours. However, some programs and institutions specifically require TOEFL or IELTS. Always verify acceptance with your specific institution or program before taking the DET as your primary proficiency credential.
How long does it take to improve English for academic use?
Meaningful measurable improvement in academic English writing typically occurs within one semester of deliberate practice, combining formal feedback (writing center sessions, professor comments) with regular writing output. Speaking confidence in academic settings typically requires 6-12 weeks of consistent exposure and practice in the specific context (seminars, office hours, group presentations). The variable is deliberate practice in the right context, not time alone.
What free resources are available for English improvement at US universities?
Every US university has a writing center (free sessions on your academic writing), usually a conversation exchange or language partner program, and access to LinkedIn Learning through the library at most institutions. The Purdue Online Writing Lab (owl.purdue.edu) is the best free online resource for US academic writing norms. Campus tutoring centers also often include English language support. Use these before spending money on private tutoring or paid programs.
