If you're aiming for a Spanish-language certification, DELE B2 is the most recognized option — but it's not the only one. SIELE and OPIc (ACTFL) are strong alternatives, each with trade-offs in cost, format, and validity. This comparison strips away the marketing and helps you decide based on your actual needs.
DELE B2 vs SIELE: Key Differences
DELE B2 is issued by the Instituto Cervantes and is valid for life. SIELE is a newer, fully digital exam that grades on a scale (A1–C1) and expires after 5 years.
Validity & Recognition
- DELE B2: Lifetime validity. Accepted by universities, employers, and immigration authorities worldwide.
- SIELE: Valid for 5 years from the test date. Recognized by many institutions but not by all Spanish government bodies.
Test Format
- DELE B2: Paper-based or digital (varies by center). Four sections: Reading, Listening, Writing, Speaking. Speaking is face-to-face with an examiner.
- SIELE: Fully digital, adaptive. Sections can be taken separately or together. Speaking is recorded and graded later.
Cost & Availability
- DELE B2: Fees vary by country (verify on the official portal — DELE B2 fees were last revised in early 2026). Typically higher than SIELE.
- SIELE: Generally cheaper, with more test dates and centers globally.
Who Should Choose What?
- Choose DELE B2 if you need a permanent credential, plan to work/study in Spain, or want a single, high-stakes exam.
- Choose SIELE if you need results fast, want flexibility, or are unsure about your level (the adaptive format shows your exact score).

DELE B2 vs OPIc (ACTFL)
OPIc is the oral proficiency interview by ACTFL, widely used in the US for government and corporate roles. It tests speaking only, not all four skills.
What OPIc Measures
- Speaking only: You respond to recorded prompts via computer. No reading, writing, or listening sections.
- Rating scale: Novice Low to Distinguished. A B2 equivalent is roughly Intermediate High or Advanced Low.
DELE B2 vs OPIc: Use Case
- DELE B2: Comprehensive — proves you can read, write, listen, and speak at an intermediate-advanced level.
- OPIc: Niche — ideal if you only need to prove speaking ability for a US job or academic program.
Cost & Logistics
- DELE B2: One fee covers all four skills. Test dates are fixed (usually 4–6 times a year).
- OPIc: Cheaper, available on demand, and can be taken remotely. But you'll need a separate test for other skills.
Who Should Choose What?
- Choose DELE B2 if you want a holistic certification or plan to use it outside the US.
- Choose OPIc if you're applying for a US federal job, need quick speaking certification, or already have other evidence of reading/writing ability.
Decision Matrix: DELE B2 vs SIELE vs OPIc
| Factor | DELE B2 | SIELE | OPIc | |--------|---------|-------|------| | Skills tested | All 4 | All 4 | Speaking only | | Validity | Lifetime | 5 years | 2 years (typical) | | Format | Paper/digital | Digital only | Remote/computer | | Cost | Higher | Moderate | Lower | | Best for | Permanent credential | Fast results | US jobs/speaking focus |
Final Verdict
If you need a certification that never expires and is recognized globally, DELE B2 is the clear winner. SIELE is a solid backup if you need quicker results or a lower price point. OPIc is only worth considering if your goal is specifically speaking proficiency for a US context.
