Should Well Educated Be Hyphenated?

Thanks. No. A hyphen in well educated, well read, well informed, etc., is necessary only when the phrase functions as a modifier.

Is well educated one or two words?

well-educated and well-dressed are hyphenated adjectives from the adverb well, referring to a participle adjective like educated or dressed. It should be taken as a unit. Therefore if you say "better educated" you break the unit.

Should well studied be hyphenated?

To summarize, well requires a hyphen when it functions as part of a compound adjective (generally when it precedes a noun). There is no hyphen when well functions as an adverb (usually following the noun being modified and a linking verb, such as to be), or when it is qualified (as in extremely well groomed).
