"Assassination Classroom" and "Cross Road" are both anime that involve a school setting and was sponsored by Z-KAI - a Japanese company running cram schools and correspondence courses for students.
These two works teach the importance behind a good education as well as how efforts must be put in by both the educator and the student for a good learning experience.
