Portugal's citizenship test: the 5 themes and their limits

Portugal's citizenship test has five civic subject areas: Portuguese culture, history, national symbols, fundamental rights and duties, and the political organisation of the State. Language sits in the same sentence of the statute but has its own exam and its own rules, which is why the count is five and not six.

That list is not published by any authority. It is read off two sub-paragraphs of the Nationality Law, as amended by Organic Law 1/2026 — and there is, as of 2 August 2026, no syllabus, no weighting and no question bank behind it. The gap between “the law names these subjects” and “here is what you will be examined on” is what this page is about. If the reform itself is new to you, read what the new nationality law changes first.

Where the themes actually come from

Sub-paragraph (c) requires applicants for naturalisation to prove, «através de teste ou de certificado» — by test or by certificate — sufficient knowledge of «a língua e a cultura portuguesas, a história e os símbolos nacionais»: the Portuguese language and culture, history and national symbols.

Sub-paragraph (d), which Organic Law 1/2026 added from scratch, requires sufficient knowledge of «os direitos e deveres fundamentais inerentes à nacionalidade portuguesa e a organização política do Estado português» — the fundamental rights and duties attaching to Portuguese nationality, and the political organisation of the State. The official text is in the Diário da República, series I, no. 95, of 18 May 2026.

Count the named objects: four in (c), two in (d), six in total. Take out language, which is proved separately, and you get the five everyone refers to. The arithmetic is sound — the label “five official themes” is not, because nothing official has labelled them.

None of this existed before 18 May 2026

This is worth stating plainly, because it explains why no long-established study material for this exam can exist. Under the previous text of the law, sub-paragraph (c) read, in full: «Conhecerem suficientemente a língua portuguesa» — sufficient knowledge of the Portuguese language. That was the entire knowledge requirement for naturalisation. No culture, no history, no symbols, no rights and duties, no organisation of the State; the old sub-paragraph (d) dealt with criminal records. The five civic themes are less than three months old.

How far does each theme actually go?

“What are the themes” is the easy question. “Where does each one stop” is the one that decides how you study. Three of the five have a traceable legal boundary. Two have none at all.

• National symbols. The tightest of the five, because the Constitution has an article by that name: Article 11, headed «Símbolos nacionais e língua oficial», covering the flag, the anthem and the official language in three short paragraphs. Anything beyond it — the heraldry of the coat of arms, for instance — comes from other legislation.
• Fundamental rights and duties. The phrase in sub-paragraph (d) is the title of Part I of the Constitution, Articles 12 to 79 — the next one already opens Part II, on economic organisation. A clean boundary, but a wide one — nearly 70 articles.
• Political organisation of the State. Starts at Article 108, «Titularidade e exercício do poder»; the article before it still belongs to the economic part. From there you get the organs of sovereignty, what each one does, and the autonomous regions.
• History of Portugal. No legal instrument defines what “history” means for this purpose. No period, no list of dates, no reference source. Anyone drawing a boundary here is making an editorial choice, not citing the law.
• Portuguese culture. The same, only worse. The Constitution mentions culture, in an article on cultural participation, but to impose duties on the State, not to define examinable material. There is no legal perimeter for “Portuguese culture”.

Why that asymmetry matters more than the list

Three themes point at documents you can read to the end. Two are, today, entirely undefined. So when a preparation site tells you the exam covers the Age of Discoveries, the Carnation Revolution and fado, it is making a forecast — possibly a good one, but nothing currently obliges the regulation to agree.

And the regulation is what has to decide. Article 4 of Organic Law 1/2026 says only that the Government shall make the necessary changes to the Portuguese Nationality Regulation, annexed to Decree-Law 237-A/2006, within 90 days of publication. Ninety days from 18 May 2026 ran out on 16 August — with no regulation, and no new date, because the provision sets the deadline and attaches no consequence to missing it. Until that changes, the Regulation contains exactly one article about proving knowledge, titled «Prova da residência e do conhecimento da língua portuguesa», on residence and language. The five civic themes have no implementing rules whatsoever.

Is language a sixth theme?

The statute answers this itself, in a place that is easy to miss. It gives nationals of Portuguese-speaking countries a presumption — but not over sub-paragraph (c) as a whole. They are presumed to satisfy «o requisito da primeira parte da alínea c)»: the requirement of the first part of (c), which is the language. The law splits the sub-paragraph down the middle and treats language separately from culture, history and symbols.

Which matches how it works in practice: the language requirement already has several accepted forms of proof. The Regulation accepts school certificates, the CIPLE, and a test sat in the state school network — the last of these governed by Portaria 176/2014 and currently run by IAVE. The civic themes have none of that yet. If you are unsure which of the two requirements applies to you, that is covered in the difference between the CIPLE and the civic test.

An oddity in the drafting worth knowing about

Read the two sub-paragraphs side by side and watch the verb. Sub-paragraph (c) says applicants must prove their knowledge “by test or by certificate”. Sub-paragraph (d) says only that they must know the material sufficiently — and names no method of proof at all. Not a test, not a certificate, nothing.

There is a second sign that this is deliberate rather than sloppy. The same law allows the Government to waive, for people who have rendered relevant services to the Portuguese State, the requirements “of sub-paragraphs (b) and (c)” — residence, and language plus the three themes attached to it. Sub-paragraph (d) is not in the waiver. Whatever the right reading is, the regulation will have to say how the rights-and-State material gets proved, and the sensible guess is that it lands in the same exam. A sensible guess is still not a rule. For who is and is not exempt, see the exemptions, one by one.

Does this only apply to naturalisation?

No — and this catches people out. The themes are written into the naturalisation article, but other routes now point back at it. A separate provision of the same law makes attribution of nationality under that route conditional on meeting the requirements in sub-paragraphs (c) to (h) of the naturalisation article, so an original nationality route now carries this subject matter. The same logic applies to stateless applicants. The distinction between the two families of routes is explained in attribution versus acquisition.

How much is each theme worth?

Undefined. No percentages, no number of questions per theme, no statement that the five carry equal weight. If you see a weighting table for this exam, someone wrote it; nobody published it. Contrast that with the language exam, which has existed for years and has verifiable rules of its own — set out in what the A2 exam actually asks of you.

What to do with this in the meantime

A defensible study order falls straight out of the above: start with the themes that cannot move. National symbols is short and closed. Rights and duties, and the organisation of the State, are long but they live in a document you can read — the Constitution — and no regulation is going to change what it says. That work will not be wasted in August.

Leave history and culture until later, and for now read broadly rather than memorising lists: those are precisely the two themes whose scope the regulation can still draw in several different ways. To see what a properly sourced question looks like in each of the five, we have worked examples with the article that answers each one — and the free practice test is organised by exactly these five themes.
