Choosing the right Spanish exam can feel overwhelming. SIELE, DELE, and CELU are the three most recognized certifications globally, but they serve different needs. This comparison cuts through the noise — we’ll look at test format, scoring, recognition, and cost so you can pick the one that fits your timeline and career goals.
SIELE Overview
SIELE (Servicio Internacional de Evaluación de la Lengua Española) is a digital, modular exam created by the Instituto Cervantes, UNAM, University of Salamanca, and the University of Buenos Aires. It’s fully online, adaptive, and results come within three weeks. You can take the full test (SIELE Global) or individual modules for Reading, Listening, Writing, and Speaking. Scores are on a 0–1000 scale, aligned with CEFR levels A1 to C1. There’s no pass/fail — you get a numeric score and a level.
Key advantages:
- Fully online — no oral examiner, just a recording.
- Modular — retake only weak sections.
- Valid for five years (unlike DELE, which is permanent).
DELE Overview
DELE (Diplomas de Español como Lengua Extranjera) is the classic paper-based exam from the Instituto Cervantes. It’s offered at six CEFR levels (A1 to C2) and is valid for life once passed. The test is in person, with a fixed schedule a few times a year. You must pass all sections to earn the diploma.
Key advantages:
- Lifetime validity — no renewal needed.
- Widely recognized for academic and government purposes.
- Traditional format with an oral interview.
CELU Overview
CELU (Certificado de Español: Lengua y Uso) is Argentina’s official Spanish certification, administered by the Universidad de Buenos Aires. It’s accepted across Latin America and increasingly in Europe. The test is in person, covers B1 to C1 levels, and is valid for five years. It focuses on practical, communicative use of Spanish.
Key advantages:
- Recognized in Argentina and Mercosur countries.
- Emphasizes real-world language use.
- Lower cost than DELE (verify current fees on the official portal — CELU fees were last revised in early 2026).

Cost & Availability
SIELE: Fees vary by country and module. In India, the full SIELE Global typically costs between INR 6,000–8,000 (verify on the official SIELE site — fees were last revised in early 2026). You can book online and take the test from home.
DELE: More expensive — a B2 level can cost INR 10,000–15,000. Limited test centers and fixed dates (usually 3–4 times a year).
CELU: Often the cheapest — around INR 4,000–6,000, but only available at select centers in India (mainly metros).
Which One Should You Pick?
If you’re short on time or want a flexible, digital option, SIELE is the clear winner. If you need a permanent credential for academia or government, DELE is unmatched. For those targeting Latin America, especially Argentina, CELU is a smart budget choice.
