U.S. High School Diploma in Spain: Homologation and University Access

On its own, your child’s U.S. high school diploma will not open the door of a Spanish university. Spain first has to declare it equivalent to its título de Bachiller, the upper secondary diploma, through homologación (homologation) under Royal Decree 104/1988. The same procedure turns grade 11 into the first year of Bachillerato, by convalidación, and grade 10 into the Graduado en ESO, the compulsory secondary title. After that, university admission goes through UNEDasiss, the distance university’s service for students from foreign systems, with extra rules in Madrid and Catalonia. This article is for informational purposes only and is not legal or educational advice; verify current requirements with the relevant Spanish authority or a licensed professional.

Is a U.S. high school diploma valid in Spain, and does a GED count?

A U.S. High School Diploma is valid in Spain once homologated to the título de Bachiller. The Ministry of Education’s 2020 U.S. country sheet rules out the GED and honorary diplomas, and UNEDasiss says programs followed online from Spain cannot be homologated.

Homologation makes a foreign title academically equal to the Spanish one, under a decree that the Ministry’s list of rules still cites. At the Ministry of Education, Vocational Training and Sports, only official studies fully completed in the foreign system are accepted. Three other things can sink or weaken your U.S. file:

• Paperwork in the wrong form. Notarized photocopies, apostilles from a state other than the issuing one, and apostilles dated before the notarization are all turned away in the Education Office’s guide.
• A missing transcript. Under the resolution of July 3, 2024, any Bachillerato-level year without its certificate counts as 5.00 in the credential’s average, and that average is not redone if the certificate turns up after the credential.
• A refusal after conditional enrollment. The volante, a stamped slip, lets your child enroll while the file is pending; should homologation be refused, the 1988 order voids that enrollment and any exam results obtained with it.

When should you apply, and what are the 2026 dates?

File for homologation as soon as possible with the grade 10 and 11 transcripts; UNEDasiss takes applications from February 4 and wants them at least 6 weeks before preinscription closes, which public universities had to keep open until July 7, 2026 for U.S. students.

The dates below are the 2026 ones: on November 9, 2026, neither UNEDasiss nor the Ministry had published 2027 dates. The Education Office’s webinar of March 18, 2026 advises filing before graduation.

1. Grade 11 or early grade 12. Have the grade 10 and 11 transcripts signed by a school official before a notary, apostilled by the school’s state and translated by a sworn translator.
2. Before graduation. Apply online, pay the fee, and file the form, the volante, the passport, the receipt and those transcripts, so that the volante receives its registry stamp.
3. From February 4. The UNEDasiss accreditation window opens; with only the volante in hand, the accreditation is provisional.
4. March 16 to April 28, 2026. This is when you apply for the May and June session of the PCE (pruebas de competencias específicas), the UNEDasiss subject tests, according to the key dates page.
5. May 25 to 29 in Spain; June 10 to 13 in New York and Seattle. These are the PCE exams, the U.S. dates coming from the webinar; results arrive by June 22.
6. June. To complete the file, send the legalized grade 10 to 12 transcripts and the diploma.
7. July 1 to 22, 2026. Applications open for the September session, with exams from September 2 to 8.
8. July 7, 2026. Under a resolution of April 23, 2026, public universities had to keep preinscription, the application for a place, open until this date for students from non-EU systems without an agreement, and take into account access grade accreditations sent by July 31 by those who applied on time.
9. October 31. The last day on which the credential or pending documents can update the UNEDasiss grade.
10. December 1. The key dates page closes the window here; the UNEDasiss FAQ says November, so plan on November.

Which U.S. grades need homologation or convalidation?

A U.S. student’s grade 12 with the diploma is homologated to the título de Bachiller, grade 11 is convalidated for 1º de Bachillerato and grade 10 becomes the Graduado en ESO, the Ministry’s U.S. sheet shows; joining primary school or ESO needs no procedure.

The transcripts come from the Ministry’s FAQ, the fees from the Education Office’s 2026 webinar and the Ministry’s Graduado en ESO page. ESO (Educación Secundaria Obligatoria, compulsory secondary education) ends with 4º ESO, and 1º de Bachillerato is the first of the two Bachillerato years; for the younger years, how to enroll your child in a Spanish school covers the step.

The subject rule for students who studied in Spain first

If your child went to school only in the U.S., the country sheet asks for passing grades in every subject but no specific subjects; Catalonia’s page adds at least one credit for every subject taken. For a student with 2 years or less in U.S. schools after Spanish schooling, the pages do not agree on the grade 12 minimum:

• the country sheet, dated February 18, 2020 by its file data: 4 listed subjects, or 5 without a diploma, three from the same group (A for sciences, B for humanities);
• the Education Office’s guide (October 2024 file data) and its March 2026 webinar: 4, three from the same group;
• Catalonia’s page on U.S. studies, updated January 24, 2025: 5, three from the same group, each worth at least one credit.

If you plan on 5 qualifying subjects, 3 from one group, each passed in both semesters and worth a credit, you meet all three versions. Where the school or state gives no diploma to foreign or partial-program students, a Carta de no Diploma from the school takes its place, along with the fifth subject.

How do you homologate a U.S. high school diploma?

To homologate a U.S. diploma, you apply on the Ministry’s e-office, which issues the volante, then file the form, the volante, the passport, the fee receipt, and the transcripts and diploma (once issued) apostilled and translated, at an official registry, per the 2026 webinar.

At a Spanish registry, staff make verified copies from your legalized originals and hand the originals back to you, the documents page says.

The state apostille. Since the U.S. is a Hague Convention country, the apostille alone is enough. The Education Office’s guide sets out two steps: first a school official signs before a notary (an acknowledgement or a jurat), then the Secretary of State of the school’s state issues the apostille. This is a different apostille from the federal one on the FBI check in the checklist for moving to Spain from the US. In Catalonia, it is the school authority itself, not the family or an agent, that must take the documents to the notary, Catalonia’s page says.

The translation. Everything, apostilles included, should be translated by a sworn translator on the Spanish Foreign Ministry’s register, the Education Office’s guide says; among other routes, the Ministry also accepts a Spanish consulate.

Filing. The procedure sheet has you print the online form and lets you file at any time of year. The filing page lists the registries of article 16.4 of Law 39/2015, the Government delegations, the Ministry and Spanish consulates abroad; whether the whole file can go through the general electronic registry, it does not say. In the U.S., files are taken by the Education Office in Washington, D.C. and the Education Attachés in New York, Miami and Los Angeles: you email one PDF, then bring the originals to an appointment, as the step-by-step guide explains.

How much does homologation cost in 2026, and how long does it take?

The Ministry of Education charges 49.76 euros in 2026 for homologation to the Bachiller, paid on form 790 code 079, and has 3 months from a complete file to decide; silence after that counts as a refusal you can appeal.

The Ministry’s 2026 form and the La Rioja inspectorate’s instructions show the webinar’s amounts, updated from the 40 and 20 euros of Law 53/2002. Under the Ministry’s payment rules, you pay in cash at a collaborating bank if you are in Spain, or from abroad by transfer to the Treasury’s account at the Banco de España, with the transfer costs on you.

Who decides. If you live in Catalonia, Galicia or the Basque Country, you file with the regional education department. Everywhere else the Ministry decides, and the Alta Inspección, the state’s education inspectorate in the Government delegations, handles files covered by equivalence tables (competent bodies). In Catalonia, a fees page updated July 23, 2026 shows 71.05 euros for the Batxillerat (Catalan for Bachillerato) and 35.55 euros for convalidation, with ESO free. The Galician and Basque fees were not checked for this guide.

The clock. Royal Decree 104/1988 sets the same 3 months, counted from the date your file is complete. An incomplete file gets 10 days to be put right, up to 3 months for foreign documents lacking formalities, or it is closed. Even after 3 months of silence, the office still owes a decision. You will not find real processing times on any official page, and Catalonia’s May 2026 instruction mentions a backlog.

The credential. This document carries the same weight as Spanish school records. Its average, the nota media, is drawn from the two years that match Bachillerato under the 2024 resolution, in force since July 31, 2024; its U.S. annex covers letter grades (2 for a D to 5 for an A), plus and minus grades, and 0 to 4, 0 to 100 and 0 to 10 scales, each turned into a grade out of 10. The 2020 country sheet still cites the repealed 2018 resolution and a minimum pass of 5 on 0 to 10 scales, whereas the 2024 annex sets 6, so plan on the 2024 rules.

Can your child start university before the decision?

Possibly: before the homologation decision, a student can apply to Spanish universities only on a provisional UNEDasiss accreditation, and each university decides whether to accept it. If homologation is refused or not granted as requested, the 1988 order voids enrollment and exam results.

You get the volante de inscripción condicional with the online form, and it only counts once it bears the registry’s entry stamp, the procedure sheet says; Royal Decree 104/1988 then lets schools admit your child conditionally. The 1988 order asks that it name the studies or exams you plan to enroll in; it serves for enrolling for 6 months from the stamp, then, once your child is enrolled, only for that academic year. If the delay is not your fault, the office may issue a new one, valid for one academic year at most. In Catalonia, an instruction of May 12, 2026 extends every pending volante through the 2026-2027 school year.

For students from non-EU systems without a reciprocity agreement, which is the U.S. case, the LOE, Spain’s education law, requires meeting the homologation requirements and passing an access test that the Government is to regulate. That regulation was still missing when the BOE last consolidated Royal Decree 534/2024, on July 2, 2026; its transitional provision keeps articles 3, 4, 9 and 10 of Royal Decree 412/2014 in force for these students, and article 4 lets universities admit a student conditionally once the student proves the homologation was requested. Royal Decree 534/2024 spares EU and agreement systems, the European Baccalaureate and the IB Diploma from homologation, but not a plain U.S. diploma, which UNEDasiss places on its track for other non-EU systems.

What UNEDasiss does. It does not homologate anything. Its FAQ calls the Bachiller homologation indispensable for its accreditation, the digital certificate for admission that carries your child’s access grade and PCE results. If you file with the volante and apostilled transcripts of the last two years (documents step), the accreditation stays provisional until the credential arrives, under UNED’s accreditation rules. For non-EU systems, it is valid for 2 years.

What grade will a Spanish university see?

UNEDasiss computes the admission grade as 0.2 times the homologated Bachillerato average plus 4, then adds 0.1 times each of up to 4 PCE subject tests passed, up to 10, its FAQ says; with no PCE, the grade lands between 5 and 6.

The grade and the tests. A PCE counts only with at least 5 out of 10, in a different subject and in the same calendar year, and universities may add up to 4 points. For example, a homologated average of 8 gives 5.6, and four PCE at 7 add 2.8, for 8.4. Your child may take up to 6 PCE, and UNEDasiss recommends at least 4 on a first application; the PAU, Spain’s own entrance exam, is not open at UNED to students from other systems. The 2026 papers are printed in Spanish and English, but answers are written in Spanish, except in the foreign-language exam; the levels of Spanish are set out in DELE exam levels, fees and dates.

Cost and timing. On the prices page, the table sits in an image named for 2025 and dated February 14, 2025, and no text says these are 2026 prices: 70 euros for the access grade, 35 euros for one PCE up to 140 euros for six, 25 euros for the Modalidad de Bachillerato accreditation, 30.30 euros to open a file and 15.15 euros of secretariat costs. UNEDasiss has up to 3 months to decide and often takes about 3 weeks, its key dates page says.

Madrid and Catalonia add their own conditions

Madrid. For the ordinary allocation of places, public universities ask non-EU students for homologation plus the Modalidad de Bachillerato accreditation, earned with at least 3 PCE; without it, only the extraordinary call is open, the Comunidad de Madrid says on a page updated June 3, 2026.

Catalonia. On the university portal, updated April 14, 2026, homologated non-EU students sit the access phase of the PAU or the PCE, and the access grade is worked out as 0.4 times the access-phase average plus 0.6 times the homologated Bachillerato average. In its September call, an applicant holding only the volante, or holding homologation but no PAU or PCE, is placed last.

Your first move this school year

This month, ask the high school for the grade 10 and 11 transcripts signed before a notary, order the state apostille and book a sworn translator (state fees are listed in how to get an apostille and a sworn translation for Spain).

That way you can file before graduation and have a stamped volante in hand when the next UNEDasiss window opens; on November 9, 2026, its 2027 calendar was not yet out.

If your child studied only in U.S. schools and graduates with a diploma, your family can file without help. Talk first to the Education Office or a licensed professional if your child had Spanish schooling and then 2 years or less in the U.S., took online classes from Spain or holds a GED, and also after a refusal or 3 months of silence. For the study stay itself, read about the Spain student visa for Americans; for a college degree, see U.S. degree recognition in Spain.
