Are there any formal assessments (e.g. tests or exams) or certifications in Old English (e.g. Beowulf) or Middle English (e.g. Chaucer)? By Old English and Middle English, I am talking about the Medieval forms of English that are not always readily comprehensible to a speaker of Modern English.
Is there any way to get tested or certified in either of these languages (or any of their dialects) in any formal or meaningful way? This could involve testing reading comprehension skills, translation (e.g. translating from Old English to modern English), composition, knowledge of grammar or vocabulary, or something similar to that. I am not asking about university degrees in Medieval English Literature, Anglo-Saxon Studies, or similar programs unless the degrees are given out on the basis of passing language exams.
