Two certificates, and the choice between them is decided by your calendar rather than by your Spanish. The DELE is a diploma from the Instituto Cervantes, sat on fixed dates on paper, awarded at one level, and valid for the rest of your life. The SIELE is a computer test you can sit almost any week, it returns a score across the whole scale instead of a pass at one level, results arrive in about three weeks, and it expires after five years.
So the question is not which is more respected. It is whether you have a deadline, and whether you are prepared to be told you failed rather than told what you scored.
The two certificates, and what is on the paper
- DELE is pass or fail and does not expire. It is issued by the Instituto Cervantes on behalf of the Spanish Ministry of Education, and once held it is held for life.
- SIELE is a score and is valid for five years. It reports a number rather than a verdict, is taken on a computer, and comes back in weeks rather than months.
- A1, A2, B1, B2, C1, C2, the six common European levels both are built on, from a first hundred words to reading anything.
- B2 is the level most universities ask for, and it is the point at which a candidate can follow a lecture rather than a conversation.
- la prueba de expresión e interacción orales, the speaking paper, which is a conversation with an examiner and is the one candidates most often underprepare.
- la prueba de comprensión auditiva, the listening paper, played once with no repeat, which is why erosion is an exam problem and not only a street one.
Pass or fail against a score, and what that changes about preparing
This is the real difference and it is easy to miss. A DELE candidate chooses a level before sitting, and the outcome is a pass or a fail at that level. Choose too high and the fee, the months and the travel produce nothing at all, not even a record of how close it was. A SIELE candidate chooses nothing: you sit, and the result places you on the scale wherever you landed, so an optimistic estimate costs you accuracy rather than the entire attempt.
That single asymmetry should change how each one is prepared for. For the SIELE, aiming high is free, and the sensible plan is to sit it earlier than feels comfortable and use the number. For the DELE, the level has to be chosen conservatively, and the honest way to choose it is not by how the reading feels: write one timed essay and record one two-minute answer, and grade those, because those are the two papers that decide the outcome. Placing yourself honestly before booking is the whole subject of the stalls every learner hits, and the way through each, where the same measurement problem turns up without a fee attached.
Nobody practises writing by hand any more
Here is the stall, and it is specific to the paper exam. Everything you have written in Spanish for the last two years has been typed, with an automatic accent, a spellchecker and the ability to reorder a paragraph. The DELE is handwritten, in a hall, with a pen.
What happens is not dramatic and it is expensive. Handwriting is slower, so the essay that took thirty comfortable minutes at a keyboard does not fit in the time. Accents that a keyboard supplied have to be remembered and placed. Spelling that autocorrect has been quietly repairing for two years turns out to be worse than anybody thought, and there is no way to move a sentence once it is written, so a plan has to exist before the first line. None of this is Spanish and all of it is marked.
The repair is cheap and almost nobody does it: write every practice essay by hand, on paper, under the clock, from the first week of preparation rather than the last. Two of those will tell you your real writing speed, which is the number the whole paper is scheduled against.
What each level is actually for
The rungs, and who is asking for each one
Levels can be sat in any order and skipped entirely, so the question is which rung somebody in your life has asked for.
- 05C2Required by almost nobody, and mostly sat for its own sake
- 04C1Where the paper stops testing Spanish and starts testing register
- 03B2What a Spanish-speaking university normally asks for
- 02B1The most commonly sat, and roughly the point of being employable in Spanish
- 01A2Accepted by Spain in a nationality file, alongside a separate culture testthe paperwork one
The rungs describe what institutions ask for and say nothing about how long each one takes, which is a different question with a much less tidy answer.
What to prepare with
The Instituto Cervantes publishes complete past papers for every level of the DELE, free, with the audio and the marking criteria. Start there and stay there. It replaced the third-party preparation book, which reconstructs the format from an older edition and gets the timings approximately right, and approximately is not useful in a hall. In 2026 there are enough published papers at each level to run a monthly mock for a year without repeating one.
The second thing is not a product. Sit one full paper by hand, timed, in a single sitting, at least six weeks before the real date. It replaced doing the sections separately whenever you had an hour, which is how most people prepare and which tests none of the things a three-hour paper tests: pace, handwriting stamina, and what your concentration does in the last twenty minutes. It costs an afternoon and it is free, and it changes the plan more than any book will.
The mistake: booking the level your reading is at
The four skills are not level with each other in anybody, and reading is almost always the one that has run ahead. Booking a DELE at the level your reading suggests means booking at the level of your best skill, and the paper is decided by your worst two.
The correction is to book at the level of your speaking, which for most people is one band lower and feels like an insult. It is not caution, it is arithmetic: a pass at B2 is a permanent diploma and a fail at C1 is a receipt. If the gap between your skills is what makes this decision hard, the general version of the problem, and how to measure it without paying anybody, is why you forget, and the schedule that beats forgetting for the retention half and what a teacher is worth, and what you can do alone for the half a machine cannot mark.
What the paper is actually for
The DELE A2 is worth knowing about even for people with no interest in exams, because Spain accepts it as the language requirement in a nationality application, alongside a separate test on culture and constitution that has nothing to do with Spanish. B2 is the level a Spanish-speaking university normally asks for, and C1 is where the exam stops testing Spanish and starts testing whether you can hold a register.
Beyond that the certificate does very little that the language itself does not, and it is worth being clear about which one you actually need. If nothing on the ladder is required by anybody in your life, the honest answer is that the fee buys a deadline, and a deadline is genuinely useful, which is a different argument and a cheaper one to satisfy with turning a vague intention into hours on a calendar. The oral is the paper that most often decides it, and preparing for that is not preparing for an exam at all, it is from present tense sentences to real conversation.
