Key takeaways
Students applying to American universities from Portugal face a fundamental mismatch. The country's secondary education follows the European model: final exams determine admission, diploma issued, done. American higher education institutions value four years of grades, standardized tests, teacher recommendations, essays, extracurriculars. Credit structures don't align. Grading scales diverge. Most US colleges approve Portuguese diplomas, but you'll need transcript evaluations, SAT/ACT scores, English proficiency proof, often supplementary coursework. Learners at the University of Lisbon or University of Porto can apply, but the process involves more steps than applying within the EU. Legacy Online School provides US-accredited curriculum from the start – no translation, no credential gaps.
- US universities accept Portuguese diplomas but require transcript evaluation and supplemental documentation
- American undergraduate programs expect different academic preparation than Portuguese Ensino Secundário delivers
- SAT/ACT required for US admissions but not part of national curriculum
- English proficiency tests (TOEFL/IELTS) mandatory for local students

Two Systems That Don’t Line Up
Portugal follows the Bologna Process, i.e. secondary education ends with exams. University admission determined by exam scores in specific subjects. Clean within Europe.
American universities evaluate differently. Four years of high school grades matter, not just final exams. Specific subject requirements exist. Standardized test scores expected. Teacher recommendation letters. Extracurricular activities assessed (pet projects, areas of interest). Personal essays required – the whole nine yards.
“In the United States, the competent authorities for recognizing previous education and qualifications include education institutions (for those seeking to study), employers (for those seeking employment), state-level licensing authorities (for those seeking professional licensure), and federal immigration authorities (for those seeking to obtain/change visa status).”
— The US Department of Education’s credential evaluation guidelines
Portuguese diplomas are recognized, but recognition doesn’t equal compatibility.
As a result, learners based in Portugal need to translate their education into a format US admissions offices understand. That costs time, money, supplementary work.
What US Universities Actually Want
Application requirements for learners in Portugal:
Transcript evaluation. Credential evaluation service (WES, ECE, similar) converts your Portuguese transcript to US grading scale. €90–€180. Takes 2–4 weeks.
Standardized tests. SAT or ACT scores required. Portuguese schools don’t prep for these. Children study independently or hire tutors. €55–€90 per attempt.
English proficiency. TOEFL or IELTS unless secondary education conducted entirely in English. Pupils almost always need this. €180–€230.
Teacher recommendations. Two or three letters. Portuguese schools don’t typically write these in US format.
Course prerequisites. Many programs – science, engineering, math especially – require specific coursework. If Portuguese curriculum didn’t cover it, you take additional courses before admission.
Essays. Personal statements, supplemental essays. No equivalent in Portuguese university applications.
US embassy visa interviews happen after admission. You need acceptance proof, financial documentation, F-1 student visa. Embassy doesn’t evaluate academic credentials – that happens during university application.
The Credit Transfer Problem
Portuguese university credits don’t transfer cleanly to institutions in North America. European Credit Transfer System (ECTS) uses different scale than US semester credit hours. One full-time year in Portugal = 60 ECTS credits. In the US, roughly 30 semester hours. Conversion isn’t automatic.
Started university in Portugal, but want to transfer to US mid-degree? Expect this:
- Each US university evaluates transfer credits individually
- Many courses won’t transfer – content or level mismatch
- You’ll retake foundational courses even if you’ve covered similar material
- Transfer credit caps vary – some schools limit it to 60 credits (two years), others accept more
NAFSA: Association of International Educators, the leading organization for international education policy, notes that transfer credit decisions depend on accreditation alignment, course content comparison, and institutional requirements.
No universal standard exists. Every school decides independently.
Starting with US Credentials Instead

Beatriz Costa: From Porto to MIT
Beatriz Costa grew up in Porto and attended a Portuguese public school through 9th grade. Her family relocated to Lisbon in 2023, and her parents didn’t want her falling behind while adjusting to a new Portuguese school mid-curriculum.
They enrolled Beatriz in Legacy’s Live Group plan in October 2023 for 10th grade. She took AP Calculus AB, AP Physics 1, and AP Computer Science A – courses unavailable in Portuguese secondary schools. By 11th grade, she scored 5 on all three AP exams.
Beatriz applied to MIT, Carnegie Mellon, and University of Texas at Austin for Fall 2026 admission. Her Legacy transcript showed four years of coursework aligned with US university expectations. No credential evaluation needed. No transcript conversion. SAT score: 1520. TOEFL waived – Legacy instruction in English satisfied proficiency requirement.
MIT accepted her for Computer Science in March 2026. The university recognized all three AP credits, placing her directly into advanced coursework. Beatriz starts freshman year this fall with sophomore standing in mathematics – saving an entire semester and over $30,000 in tuition.
Legacy didn’t just prepare her academically. It eliminated the translation problem entirely.
Already Enrolled at a Portuguese University?
Currently at University of Porto, University of Lisbon, another Portuguese institution, considering transfer to US university for graduate or undergraduate completion? Process is harder than starting with US credentials.
You’ll need:
- Official Portuguese university transcripts
- Course-by-course credential evaluation
- TOEFL/IELTS if not already submitted
- New application materials (essays, recommendations)
- Proof of funding for remainder of degree in US
Many learners finish degree in Portugal, apply to US graduate programs afterward. Graduate admissions more flexible with international credentials than undergraduate transfers.
Exchange vs. Degree Programs
Exchange programs between Portuguese and American universities exist. Temporary. Study in the USA one semester or year, return to complete degree in Portugal. Credits transfer back under pre-approved agreements.
Different from full undergraduate enrollment at US university. That requires full admissions process.
Goal is US degree, not semester abroad? Plan accordingly. Starting with US-accredited high school like Legacy sets you up correctly.
Book a trial class or talk to admissions team about how students in Portugal use Legacy for US university prep. Summer school and part-time K–12 available.
Top Tips from Our Expert
Maya Robinson, College Prep Advisor at Legacy Online School
- Start junior year at latest if you’re in Portuguese secondary school targeting US universities. You need minimum one year for SAT/ACT prep, TOEFL scores, teacher recommendations, applications. Senior year is too late.
- Budget €500–€1,000 just for application costs before tuition. Transcript evaluation, test fees, application fees to multiple schools – it stacks up fast.
- AP courses save time and money. US universities give credit for AP scores of 4 or 5. That eliminates semesters of undergraduate coursework. Legacy offers 19 APs. Use them.
- Don’t assume Portuguese coursework transfers. Even advanced Portuguese math or science may not count as equivalent. Check program prerequisites at target schools before assuming coverage.
- Get US credentials if you’re serious about a US degree. WASC-accredited diploma eliminates translation problem. You’re inside the system, not fighting it.
