Key takeaways
Moving to Portugal with children means choosing between the Portuguese education system and alternatives that keep your child on a different pathway. Education in Portugal runs ages 6–18: three cycles of basic education (Ensino Básico, grades 1–9) plus secondary education (Ensino Secundário, grades 10–12). Local public schools are free, structured, high-quality – and taught entirely in Portuguese. For newly arrived expat families in Lisbon or Porto, the language barrier hits immediately. Children are assessed and taught in Portuguese, expected to integrate into Portuguese-language classrooms. International schools offer English instruction but charge €15,000–€25,000+ annually per child. American online K-12 programs like Legacy provide a third option: US curriculum, English instruction, live daily classes, full academic continuity if you relocate. Neither system is objectively better – they serve different needs.
- Local public schools free for ages 6–18, covering basic education (grades 1–9) and secondary (grades 10–12)
- Instruction entirely in Portuguese – steep language challenge for expat children
- National curriculum with structured cycles, exams ending each cycle, Ministry of Education oversight
- International schools cost €15,000–€25,000+ per child annually

How Education System in Portugal Actually Works
“This decree-law establishes the curriculum for basic and secondary education, the guiding principles for its design, implementation and assessment of learning, in order to ensure that all students acquire knowledge and develop the capacities and attitudes that contribute to achieving the competencies set out in the Student Profile upon Completion of Compulsory Education.”
— Decreto-Lei n.º 55/2018, Diário da República
Education compulsory age 6 through 18 or secondary completion. Structure:
First Cycle (Grades 1–4), ages 6–10: Foundational literacy, math, environmental studies. One teacher handles most subjects. Continuous assessment, no high-stakes exams yet.
Second Cycle (Grades 5–6), ages 10–12: Subject-specific teachers. Portuguese, math, foreign language (usually English), sciences, history, geography. Assessment becomes formalized.
Third Cycle (Grades 7–9), ages 12–15: Broader subjects. National exams end of grade 9 determine secondary progression. These matter.
Secondary (Grades 10–12), ages 15–18: Students choose pathway – science/tech, socioeconomic, humanities, or vocational. Grade 12 national exams determine university eligibility.
Expat families relocating in two years? Different calculation.
The Language Problem – Learning Portuguese
Local public schools teach in Portuguese. Full stop. Your 10-year-old from Texas attends classes entirely in a language they don’t speak. To study math, science, or history, your child needs to learn Portuguese.
Some schools offer language support classes for foreign students. Supplementary. Core curriculum doesn’t slow down. Your child keeps pace while learning instruction language simultaneously.
Younger children (6–8) acquire language faster. First-grader can reach conversational fluency within a school year if properly immersed. Older children (12–16) entering mid-curriculum face steeper challenges. Behind in content, behind in language, facing exams determining academic progression.
“Integration support for students with migrant background varies significantly by municipality and school, with no standardized national framework for language instruction to non-native speakers.”
— Eurydice, the European Commission’s education network
Whether your child gets meaningful support depends on assigned school. Not guaranteed.
What Portuguese Schools Do Well
Free. Local public schools charge no tuition. Books provided. Meals subsidized.
Structured curriculum ensures consistency. Child in Porto learns same material as child in Lisbon. Standards clear, progression predictable.
Strong foundation in mathematics, sciences, literacy. International assessments (PISA, TIMSS) rank Portuguese learners well compared to European peers.
Perfect preparation for Portuguese universities. Secondary pathway aligns with University of Lisbon, University of Porto admission requirements.
Community integration. Your child makes Portuguese friends, learns language, integrates locally. Valuable for long-term residence.
What Makes It Hard for Expats
School year runs mid-September to mid-June. Different from US (late August–early June) and UK calendars. Moving mid-year? Your child loses time.
Grading doesn’t transfer. Portugal uses 0–20 scale. US uses letters/percentages. UK uses levels. Converting transcripts requires credential evaluation – universities may not recognize cleanly.
No AP courses. Advanced Placement – currency of competitive US admissions – doesn’t exist in Portuguese system. Child planning American universities needs APs separately, outside school.
Limited flexibility. National curriculum fixed. Can’t opt out subjects, can’t accelerate easily.
Extracurriculars vary. Sports clubs, arts, music exist but aren’t standardized like American/British systems. Some schools extensive, others minimal.
International Schools: Expensive Middle Ground
International schools in Lisbon, Porto, Algarve offer English instruction, British or IB curriculum, globally mobile students. Built for expats. Solve language problem.
Cost €15,000–€25,000+ per child annually. Add uniforms, fees, extracurriculars – €18,000–€30,000. Two children? €40,000–€50,000+.
Works for families on corporate packages with education allowances. Everyone else? Prohibitive.
American Online K-12: Third Option
Legacy operates under WASC accreditation – same standard governing leading US private schools and universities. Full K-12 in English, aligned with American system, live daily classes, qualified teachers.
Curriculum from FlexPoint Education Cloud via Florida Virtual School. Core subjects plus 19 AP courses at high school level.
Three plans:
Live Group: Daily lessons, up to 15 children. Real-time teacher interaction. Scheduled like traditional school, accessible anywhere.
One-on-One: Individualized. Good for specific learning needs, unusual schedules, advanced goals.
Self-Paced: Flexible. Students work on own schedule. Teachers grade, provide feedback. No synchronized times.
All produce same WASC outcome. Choose what fits your family.
Advantage for Portugal families: portability. Enroll in Lisbon, relocate to Porto, Algarve, Madeira – or leave Portugal for the UAE, UK, or back to the US – education doesn’t restart. Same school, curriculum, teachers. No transcript conversion, no lost credits
College Board affiliated, school code 000114. AP scores reported directly. Transcripts WASC-verified with QR codes. US university pathway seamless.
Cost: significantly below international schools. Current tuition and fees. For multiple children, savings substantial.
When Portuguese Schools Make Sense
Long-term stay (5+ years minimum, possibly permanent). Child young (6–8), can acquire Portuguese fast. You want full cultural/linguistic integration. Targeting Portuguese universities. Budget primary concern, international fees unrealistic.
Then Portuguese public school works. Free, effective, prepares for Portuguese higher education.
When American Online K-12 Curriculum Makes Sense
Temporary assignment (1–3 years), will relocate. Child mid-curriculum, losing continuity sets them back. Targeting US/international universities prioritizing American credentials. Child struggles with language immersion or has learning needs requiring individualized support. Want flexibility combining Legacy with Portuguese tutors, local sports, community activities. International fees prohibitive but still want English, US-aligned education.
Legacy fits those scenarios. Not replacement for Portuguese schools everywhere – right fit when circumstances don’t align with what Portuguese system delivers.
Real Case: The Martins Family in Porto
Sofia and João Martins moved from Brazil to Porto in 2025 on EU residence permit. Two children – 8 and 13 – had attended Brazilian international school following US curriculum. Family planned three years Portugal, then potentially US for work.
Portuguese public schools: free, good reputation. But 13-year-old would enter third cycle mid-stream, in Portuguese, national exams looming end grade 9. 8-year-old could adapt faster, but family didn’t want children on divergent pathways.
International schools quoted €18,000 per child annually. Two children, three years – over €100,000.
Enrolled both Legacy Live Group October 2025. 8-year-old elementary school. 13-year-old middle school, staying on Brazil curriculum track. November, Legacy issued both Enrollment Confirmation Letters.
Arranged Portuguese tutoring locally – two hours weekly, private tutor Porto. Children attend local sports for social interaction. Legacy handles academics.
If family relocates US 2028 as planned, both transition American schools seamlessly. No lost credits, no conversion, no catching up.
Combining Systems
Some families use both. Enroll Portuguese public for language immersion, social integration. Add Legacy part-time K–12 for APs, college prep, English academics.
Or Legacy primary, arrange Portuguese classes, sports, community locally. Not locked one or other exclusively.
Summer school available for acceleration, catch-up after moves, academic engagement during long European summer holiday.
Book trial class or talk admissions team about how families across Portugal use Legacy.
Top Tips from Our Expert
Maya Robinson, College Prep Advisor at Legacy Online School
- Child under 8, staying long-term? Portuguese public works. Language acquisition fast at that age. But 2–3 year assignment, child 10+? Language immersion challenge is real.
- Don’t underestimate switching systems mid-stream. Grade 7 entry faces not just language but content gaps – Portuguese history, literature, European perspective subjects. That’s a full year struggle, not weeks catch-up.
- International fees aren’t negotiable. €20,000+ per child standard. Two or three children, run total over three/five years. Number gets uncomfortable.
- APs matter for US universities. Portuguese schools don’t offer. International schools may, charge extra. Legacy includes 19 APs. Use strategically from 9th grade.
- You can combine. Legacy academics, Portuguese tutors language, local sports community. Not all-or-nothing.
