The Spanish university system uses a centralized and rigorous framework for international student admissions, managed primarily through the UNEDasiss platform.
As an initiative of the Universidad Nacional de Educación a Distancia (UNED), it functions as the essential administrative bridge between foreign educational systems and Spanish higher education.
Each year, UNEDasiss assesses the transcripts of thousands of students, ensuring their previous studies are recognized within the Spanish grading scale.
Key Takeaways:
- The Essential Bridge: UNEDasiss is the centralized body that converts international grades into a base Spanish score of up to 10 points. It also manages the specific PCE exams that you will need to help push your final university admission score to the maximum 14 points
- The Official Accreditation: This digital certificate serves as a verified academic record that Spanish universities check in real-time. It ensures international applicants are evaluated fairly against domestic students who finished the Spanish Bachillerato.
- Choosing Your Modality: Students must pick one of four academic tracks, like Science or Arts, to align with their target degree. You typically need to pass three subjects to unlock a modality, though Madrid universities often require four.
- The Volante Connection: You can upload a Volante de Inscripción Condicional to get a provisional accreditation if your final diploma validation is pending. This status allows you to sit for exams and meet June application deadlines on time.
- Understanding Service Fees: Basic file processing costs between €50 and €100, plus approximately €40 – €50 for each PCE subject exam. An official digital certificate with a secure verification code costs an additional €35.86.
- Support and Accessibility: General phone support is available on weekdays until 14:00, while technical help for portal errors extends to 20:00. You can also book personalized video calls or in-person sessions through the Cita Previa system.

What is UNEDasiss?

UNEDasiss is the specialized body responsible for evaluating the academic eligibility of students with international diplomas. It serves two primary functions:
- Academic Assessment: It converts original grades from a student’s home country into the Spanish 0-10 point scale.
- Examination Management: It conducts Specific Competency Tests (PCE), which are subject-specific exams that allow students to increase their admission score to a maximum of 14 points.
By centralizing these services, UNEDasiss creates a level playing field between international applicants and domestic students who completed the Spanish Bachillerato.
The UNEDasiss Accreditation (Acreditación)

The core output of this process is the UNEDasiss Accreditation, a digital certificate that serves as your standardized academic record for Spanish universities.
- Standardization: It is a formal assessment verified for use by Spanish universities, not just a simple translation of your grades.
- Digital Verification: Universities have access to a digital verification tool that allows them to check your credentials in real-time, speeding up the pre-enrollment phase and minimizing the risk of fraud.
- Finality: For students from systems with reciprocity (like the EU or IB), this accreditation is often the only document needed for entry.
Which Academic Track Should I Pick?

To qualify for specific degrees, students must achieve a “Baccalaureate Modality” (Modalidad de Bachillerato) that aligns with their desired field of study. There are four official tracks:
- Sciences and Engineering
- Health Sciences
- Arts and Humanities
- Social and Legal Sciences
Your chosen track dictates which specific PCE exams you must take. For example, the Sciences track requires subjects like Mathematics II or Physics.
Beyond just choosing a track, you will need to select the right mix of UNEDasiss services to build your file. Here is a breakdown of the services you can purchase:
| Service Category | Purpose | Target Demographic |
| Grade Conversion | Converts foreign GPAs to the Spanish 0-10 scale. | All international students. |
| Specific Competency Tests (PCE) | Subject-specific exams (up to 6) to improve entrance scores. | Non-EU and competitive EU applicants. |
| Subject Recognition | Validates home curriculum subjects as equivalent to PCE exams. | EU, IB, China, and Colombia systems. |
| Language Certification | Accredits B1, B2, or C1 levels in Spanish or other languages. | Non-native speakers. |
Pro-Tip: If you are aiming for high-demand programs like Medicine or Engineering, you must reach the 14-point threshold by taking PCEs in subjects like Physics, Chemistry, or Biology.

GPA Conversion and the 14-Point Admission Score

A common misconception is that UNEDasiss gives you a score out of 14. In reality, UNEDasiss calculates your base admission score out of 10 points.
The final 4 points are added later by the specific Spanish university you apply to.
Here is how UNEDasiss calculates your base score (Calificación de Admisión) if you require degree validation:
Base Score = (0.2 x NMB + 4) + 0.1 x M1 + 0.1 x M2 + 0.1 x M3 + 0.1 x M4
- NMB (Nota Media de Bachillerato): Your high school GPA converted to the Spanish scale.
- M1 to M4: Your scores on up to four PCE exams (you must score at least a 5/10 on an exam for it to count).
Reaching the 14-Point Maximum
Once UNEDasiss issues your base score out of 10, the universities look at your two best PCE scores related to your degree. They multiply those scores by a weighting factor (usually 0.1 or 0.2) depending on how relevant the subject is to the degree.
Final University Score = UNEDasiss Base Score + (a x E1) + (b x E2)
If you score a perfect 10 on two highly relevant PCE exams (weighting of 0.2), the university adds 4 points to your UNEDasiss base score, bringing you to the ultimate 14 points needed for highly competitive programs like Medicine.
Uploading the Volante: Using the Conditional Enrollment Slip (Volante de Inscripción Conditional)
As discussed in our guide to the Volante de Inscripción Condicional, this provisional document is a vital component of your UNEDasiss file.
While UNEDasiss does not perform the legal validation (Homologación) of your degree, it requires proof that you have initiated the process with the Ministry of Education.
If your Homologación is still in progress, UNEDasiss will issue a “Provisional Accreditation”. This allows you to sit for exams and apply for university spots while waiting for your final legal certificate.
