Can degrees be "established"?

I wanted to convey that a university degree is true and valid, but I am not sure if the word "established" can be used for the degree itself.

1. Any suggestions on which words I can use to convey that same meaning for a "degree"?

2. Can I check if it is the word "established" can be used for an educational program?

Solution 1:

I don't think claiming a PhD is an established degree will convey any valuable information to the reader.

I believe the words you're looking for are recognized, reputable, prestigious. You may also pick nouns that are directly related to degrees: Graduates, diplomas.

Solution 2:

You can establish the validity or legitimacy of a degree. You can also state that a degree is authentic, legitimate, genuine or bonafide. You can also use similar adjectives to describe the institution which conferred the degree.

You can find related synonyms in a thesaurus.
