Despite some initial concerns, the teacher is confident that her students mastered the lesson.

this is a sentence.
here the teacher is confident is the independent clause and that her students mastered the lesson is a dependent clause(noun clause) .

and therefore (that her students have mastered the lesson ) should be a adverbial clause as it behaves like an adverb by modifying adjective confident .
