Sign Language Proficiency Tests (French, British, Brazilian)
Been doing some research on language exams recently and ended up in a bit of a rabbit hole on sign languages. I had mostly heard of sign language proficiency being measured in the context of interpreters, but turns out there's a couple of CEFR-like, government-approved proficiency tests out there!
I'm sure there's more, but here's a quick list I found:
I posted about the DCL in a professional context before, and it covers French Sign Language Proficiency and grants a nationally-valid diploma.
Signature, a charity in the UK administers a BSL proficiency test regulated by Ofqual. BSL is officially entering the GCSE curriculum in 2 weeks from now.
The Prolibras test administered by the Ministry of Education (MEC) assesses proficiency in Libras, a language that has its own celebration day (24 April) in Brazil!
