How to Improve Your English Before Starting US High School

Last Updated: April 2026

How to improve English before studying abroad is a practical question that shapes academic success from the very first week of school. Improving your English before studying abroad means building the vocabulary, grammar, listening, and writing skills required to participate in US high school classes without a language barrier slowing your progress. According to IIE Open Doors (2025), international student enrollment at US secondary schools has grown consistently, with students arriving from over 200 countries, many of whom face academic English as a distinct challenge separate from general conversational fluency.

Amerigo Education partners with 40 Niche A+/A rated schools across the US, Canada, and the UK, supporting 3,500+ students from 55+ countries. The Class of 2025 achieved 97% admission to Top 100 US universities. Importantly, 96% of students who entered with B1-level English proficiency still achieved Top 100 admission, a result driven in large part by in-school customized ELL (English Language Learning) courses and structured academic support from arrival.

Key Takeaways

• ELL program outcomes: 96% of B1 English entrants in the Class of 2025 achieved Top 100 university admission, showing that language level at arrival is not a barrier to elite outcomes.
• In-school ELL: Amerigo partner schools offer customized ELL courses designed for international students' specific academic needs.
• Study structure: Structured study hours with campus staff available help students apply English skills to real assignments each evening.
• Low-B1 outcomes: Even students who entered with low-B1 proficiency achieved an 83% Top 100 admission rate in the Class of 2025.
• English tests accepted: Partner schools accept TOEFL, IELTS, Duolingo English Test, and Eltis for admission purposes.

What English Level Do You Need for US High School?

Most US private high schools expect international applicants to demonstrate English proficiency through a standardized test, typically TOEFL (Test of English as a Foreign Language), IELTS (International English Language Testing System), Duolingo English Test, or Eltis. The minimum score required varies by school, with many selective institutions expecting TOEFL scores between 60 and 80 for admission into supported English tracks. Students who arrive below these thresholds may be placed in ELL courses rather than standard academic tracks from day one.

Amerigo partner schools accept all four of the major English proficiency tests mentioned above and use results to place students in the appropriate course level. Under F-1 regulations, the F-1 (student visa for academic programs) application process requires evidence of enrollment at a SEVIS (Student and Exchange Visitor Information System)-certified school, and schools that use ELL placement ensure compliant academic programming. Students do not need to be fluent to enroll, but arriving with at least conversational B1-level English makes the first semester significantly easier.

Which English Skills Matter Most Before Arrival?

Academic English differs from conversational English in four specific ways: reading complexity, writing formality, listening comprehension speed, and discipline-specific vocabulary. Before starting US high school, students should focus on building academic reading fluency, which means the ability to read dense textbook passages and extract key arguments. This skill is tested in nearly every subject, from history essays to science lab reports. Many students can converse comfortably in English but struggle when assigned a 15-page chapter with technical vocabulary in biology or economics.

Writing in English at high school level requires more than grammar accuracy. Students need to structure arguments, cite evidence, and write in formal academic register, a skill set that takes months to develop. Listening comprehension in a fast-paced American classroom, where teachers rarely slow their speech for non-native speakers, is another critical skill. Working on these four areas before departure directly reduces the learning curve after arrival. See How Long Does It Take International Students to Go from Basic English to AP Classes? for a timeline-based guide.

1. Academic reading fluency in subject-area texts
2. Formal academic writing, including argument structure and citation
3. Listening comprehension in native-speed American English
4. Discipline-specific vocabulary in math, science, history, and literature
5. Grammar accuracy for written assignments and tests
6. Speaking confidence for class participation and presentations
7. Note-taking skills in English during fast-paced lectures

How Can You Improve English Before Departure?

Improving English before studying abroad requires consistent daily practice across reading, writing, listening, and speaking. Students who make the most progress before departure typically combine structured preparation with immersive exposure to English-language media and academic materials. Spending 60 to 90 minutes each day on targeted English practice for three to six months before departure can move a student meaningfully from low-B1 toward a stronger B1 or even B2 (independent user) level.

According to the American Council on the Teaching of Foreign Languages (ACTFL, 2024), structured daily exposure to academic-level materials in a target language accelerates proficiency gains faster than informal exposure alone. Students preparing to enroll at Amerigo partner schools can access pre-departure planning webinars that provide guidance on what to study and how to prepare before leaving their home country. See How to Prepare for Studying Abroad: Complete Guide 2025 for a full pre-arrival checklist.

1. Read English-language news articles and summarize them in writing daily
2. Watch US high school-level documentaries or academic YouTube channels in English
3. Practice TOEFL or IELTS sample tests weekly to track progress
4. Write one academic paragraph each day in English on a topic related to your intended subjects
5. Use vocabulary flashcard apps to build subject-specific word banks
6. Find a conversation partner who is a native English speaker or advanced learner
7. Listen to English-language podcasts at normal speed, then slower speed playback
8. Read one English-language novel or graded reader per month before departure

What ELL Support Does Amerigo Provide After Arrival?

Amerigo partner schools offer in-school customized ELL courses designed specifically for international students who need language support alongside their standard academic program. These are not generic ESL (English as a Second Language) classes. The courses are tailored to match the vocabulary and reading demands of the specific subjects students are taking that semester, so a student in a biology class gets ELL support that directly helps with biology reading and writing tasks.

Evening structured study hours with campus staff available give residential students a daily opportunity to apply what they learned in ELL classes to their actual homework. Dedicated common areas for group study with teacher availability mean students can ask questions in real time while completing assignments. For students in homestay, the on-campus international department provides a separate point of contact during school hours for academic support and ELL-related questions.

How Do ELL Students Progress to Advanced Courses?

Students who enter with B1-level English and complete in-school customized ELL courses can progress to AP (Advanced Placement) and Honors classes as their language skills develop. Amerigo's individualized academic planning includes identifying prerequisite courses that prepare students for AP enrollment, and ELL placement is integrated into this planning process from enrollment. Students are not placed in AP courses before they are ready, but the goal of the academic planning process is to map a realistic pathway from ELL to advanced coursework within the student's program timeline.

The Class of 2025 results provide concrete evidence of this progression. Among B1 English entrants, 96% achieved Top 100 university admission. Among low-B1 entrants, 83% achieved the same outcome. The Top 100 Guarantee, known as Amerigo's Top 100 Guarantee, requires eligible students to complete two consecutive years of enrollment, maintain a cumulative GPA of 3.2 or above, achieve TOEFL 85 or higher, and complete at least one AP, IB, or Honors course. This means the ELL-to-AP pathway is not just possible but formally structured into Amerigo's program design.

1. Enter with placement test and TOEFL or IELTS score
2. Begin in-school customized ELL track matched to your academic subjects
3. Complete structured study hours to apply ELL skills to nightly homework
4. Progress through ELL levels as proficiency improves over one to two semesters
5. Take prerequisite courses to qualify for AP or Honors enrollment
6. Enroll in at least one AP, IB, or Honors course to meet Guarantee criteria
7. Build a US high school transcript that reflects advanced academic achievement

How Do Families Track English Progress?

Amerigo sends monthly progress reports to families for all students, covering academic performance including progress in ELL courses. These reports let parents see how their student's English skills are developing alongside their overall GPA (Grade Point Average) in subject classes. When a student's progress requires immediate attention, Amerigo staff reach out in real time rather than waiting for the scheduled monthly report.

Amerigo Education provides native-language communication support for families from China, Vietnam, Korea, Mexico, the Taiwan Region, and more, ensuring parents can fully engage with their student's ELL and academic progress in their first language. The school activity calendars shared by Amerigo with families also include ELL-related events, placement reviews, and academic planning meetings.

Frequently Asked Questions

How long does it take to improve English before studying abroad?

The time needed depends on your starting level. A student at A2 (elementary) level who studies consistently for one hour daily may reach B1 in four to six months. A student already at B1 can reach a stronger B1 or early B2 in three to four months of focused preparation. Progress is faster when students combine grammar study with active reading, listening, and writing practice rather than using any single method alone. Consistency over weeks and months matters more than intensity in short bursts.

What English test should I take for US high school admission?

Most US private high schools accept TOEFL, IELTS, Duolingo English Test, and Eltis. Amerigo partner schools accept all four. TOEFL is the most commonly requested test for US university admission and is worth prioritizing if your student plans to apply to US universities. However, schools use multiple tests for high school admission, so families should check the specific requirements of their target school. Amerigo advisors can help families identify which test to take and when to register.

Can a student with low English succeed at a US high school?

Yes. The Class of 2025 data shows that 83% of students who entered with low-B1 English proficiency achieved Top 100 university admission. This outcome is supported by in-school customized ELL courses, structured study hours with campus staff, in-residence homework help, and individualized academic planning. Students are not expected to be fluent on arrival but must commit to daily practice and take advantage of the ELL and academic support systems available through their program.

Does Amerigo offer ELL support for homestay students too?

Yes. Students in homestay accommodation access academic support, including ELL-related guidance, through the on-campus international department office at their partner school during school hours. They can also schedule meetings with Amerigo academic counselors and access subject-specific tutoring where available (additional costs may apply). Monthly progress reports are sent to homestay families as well, covering ELL and academic performance together.

What is the difference between ELL and ESL courses?

ELL (English Language Learning) is a broad term covering language instruction designed for non-native speakers at any proficiency level. ESL (English as a Second Language) is an older term for similar instruction but often refers to more general language practice. Amerigo's in-school customized ELL courses are specifically designed for the academic vocabulary and skills required in US high school subjects, making them more targeted than general ESL programs. The goal is to help students succeed in their core subject classes, not just improve general communication.

How many accommodation options does Amerigo offer?

Amerigo offers four accommodation options: homestay, off-campus residences, on-campus residences at select partner schools, and self-provided accommodation for students with nearby family. Both homestay and residential students receive monthly progress reports and have access to academic support. Off-campus residences include 24/7 staff, structured study hours, and in-residence homework help. Homestay provides cultural immersion and a more affordable experience. Families should review Amerigo's student accommodations page to compare options.

What is the Top 100 Guarantee and does English level affect eligibility?

Amerigo's Top 100 Guarantee covers a refund of up to $50,000 USD for eligible students who do not gain Top 100 university admission. Requirements are: two consecutive years of enrollment at a US Signature School, cumulative GPA of 3.2 or above, TOEFL score of 85 or higher, and at least one AP, IB, or Honors course. The TOEFL 85 requirement means English proficiency must reach a specific threshold, and Amerigo's ELL program is designed to help students reach that level within their enrollment period.

Should I use apps or classes to improve English before departure?

Both are useful, but for different purposes. Language apps like Duolingo or vocabulary platforms are effective for daily word-level practice and building study habits. Structured classes with a teacher provide accountability, feedback on writing and speaking, and the ability to ask questions about grammar and usage. The most effective pre-departure preparation combines both: use apps for daily vocabulary and listening practice and enroll in a structured course to build writing and speaking skills under guidance. Amerigo's pre-departure webinars can help students understand which areas to prioritize.

Which subjects require the strongest English skills in US high school?

English Language Arts and History require the strongest academic reading and writing skills, as both subjects involve dense texts, essay writing, and argumentative analysis. Science subjects require scientific vocabulary and the ability to write lab reports in formal English. Mathematics uses less academic English overall but still requires reading comprehension for word problems and test instructions. Students preparing for US high school should prioritize building academic reading and formal writing skills, as these apply across the most subjects.

Does speaking English with a strong accent affect high school performance?

Accent does not directly affect academic performance, as US high school grading is based on written work, tests, and class participation quality rather than pronunciation. However, a strong accent combined with limited vocabulary can make class participation and teacher communication harder. Improving spoken clarity, not elimination of accent, helps students feel more confident in discussions and presentations. Amerigo's structured study hours and evening study groups provide daily practice environments where students can build speaking confidence in a supportive setting.

Conclusion

Improving English before starting US high school is the most direct investment a student can make in their first-year academic experience. The Class of 2025 data from Amerigo partner schools shows that students who arrive with B1-level English and engage fully with in-school customized ELL courses and structured study support achieve Top 100 university admission at a 96% rate. Even students who arrive with low-B1 English achieve an 83% Top 100 rate, confirming that language level at enrollment is a starting point, not a ceiling.
