Many languages have many reputable ways to get certificates, which makes it easy for employers or schools to access the knowledge of the applicant (e.g. Cambridge and TOEFL for English, Goethe for German).
Are there currently any options to get certifications at any level of Esperanto (A1-C2 or any other scale)?
Are any of the tests for higher levels (the ones that require assessment of comprehension and speaking) available online?
