Find the right language proof before you book an exam.

Break the decision into four practical stages

  1. Identify the receiving organisation

    Start with the authority, institution, employer, regulator, or exam body that will receive your proof.

    Choose a purpose
  2. Confirm the proof level

    Check the source that receives your file before treating any A1, B1, B2, or other level as suitable.

    Browse level guides
  3. Compare accepted exams

    The same level can map to different certificates. Acceptance depends on the receiving organisation.

    Compare exams
  4. Verify before acting

    Recheck centre status, dates, fees, ID rules, result timing, and submission requirements before payment.

    Build a checklist

Enter through tools or guides

Tools narrow the route. Guides explain the boundary, official checks, and supporting evidence.

Trust comes from clear boundaries

Route first. No invented facts. Identify the receiving organisation, then verify changing requirements with its official source before choosing an exam. When a stable source is missing, use the verification task provided. Governments, institutions, exam owners, and authorised centres remain the final source for requirements, acceptance, fees, dates, and individual outcomes.
