Having recently arrived in Spain, I feel that language is still the biggest hurdle. In both work and daily life, I can get by with gestures, but it never feels quite authentic. I want to study systematically and get a certificate to validate my learning. After some research, I found that the most discussed exams are DELE and SIELE, but choosing between them is a bit overwhelming. I’ve spent some time compiling materials on [self-studying Spanish] and asked friends who’ve taken the tests. Today, I’m starting this thread to share what I’ve learned and hopefully help others facing the same dilemma.

DELE vs. SIELE: First, Understand the Differences
Simply put, DELE is the ‘established champion,’ while SIELE is the ‘rising star.’ Both are officially certified by the Instituto Cervantes, so their authority is unquestionable, but their focus and format are completely different.
DELE is like a traditional proficiency exam; you choose the level you want to take and prepare specifically for it. Once you pass, the certificate is valid for life, just like a driver’s license. Therefore, it’s more suitable for learners who have a clear understanding of their proficiency level and want a permanent proof of their skills from [self-studying Spanish].
SIELE is much more flexible. It’s a computer-based test, and you can take all four sections (reading, writing, listening, and speaking) at once or test individual skills. It provides a score that corresponds to the CEFR levels, and its validity is 5 years. It’s especially suitable for those who need a quick result for university or job applications, or for those who are unsure of their exact level and want a baseline assessment.
Quick Comparison: An At-a-Glance Chart
To make it more intuitive, I’ve created a simple table for reference:
| Feature | DELE | SIELE |
| Certificate Validity | Valid for life | 5 years |
| Exam Format | Paper-based exam + in-person oral test | Fully computer-based |
| Registration Method | Register by level | Register for the full exam or individual modules |
| Result Speed | Slower, approx. 2-3 months | Fast, within 3 weeks |
| Best Suited For | Clear study plan, seeking a permanent certificate | Urgent applications, uncertain proficiency level |
Personal Prep Advice and Resource Sharing
Let me share my own experience. I wasn’t in a hurry for any applications; I just wanted to build a solid foundation. That’s why I decided to tackle the DELE B2 after some [self-studying of Spanish]. The preparation process was grueling, but the rewards were immense. The main textbooks I used were ‘Preparación al DELE’ and ‘El Cronómetro.’ These two books are very systematic and cover almost all the test points. I also highly recommend finding a language exchange partner to chat with a few times a week; it makes a huge difference for your speaking skills. For listening, I listened to Cadena SER and watched news on RTVE. At first, I could only catch a few words, but with persistence, my feel for the language improved significantly. As for writing, there’s no secret trick: just memorize sample essays, imitate their style, and ask Spanish friends to help with corrections. I hope these thoughts are helpful, and I welcome anyone who has passed the exam to add their tips! Let’s all do our best!
