Many fictional worlds show a hero working his way to fight and stop some great evil. Sometimes they're princes or knights fighting to save a damsel in distress, maybe they're mercenaries fighting evil for a paycheck or a regular person relying strictly on his wits and luck? Either way, they were defined as heroes on their respective stories.
But what if being a hero alone is to be considered a job?
Hero Academy refers to a organization, or part of an organization, that trains people to develop the skills and knowledge, usually both (or either) combat-related or otherwise, needed to be able to do heroic deeds, unlike Superhero School, it usually trains regular people with little to no superpowers and teaches their students the skills they need rather than picking out students that already have extraordinary abilities, though they may pick out individuals that they believe show potential. A subtrope of Extranormal Institute: one thing a Hero Academy has in common with Superhero School and Wizarding School that may separate it from Military School or Military Academy is that they function as a society as much as a training program. Compare Adventure Guild, which can be a faction that focuses more on having individuals go on quests than on tutoring students how to successfully go through them. The Evil Counterpart is the Academy of Evil.
- Tiger & Bunny, being a show about corporate superheroes, has one of this. Not all students have gifts that are suitable for hero-ing, however.
- Palaestra in Saint Seiya Omega, which makes the training of Saints more formalized than in the original series where training is done on master-disciple basis.
- DWMA in Soul Eater could be considered this, as they teach and train relatively normal children to become effective 'meisters' and 'weapons'. (The weapon children are naturally born with the ability to transform, but it's a trait common enough in the world to not be considered a 'super power'.) In the spinoff Soul Eater Not! it is stated that DWMA is recognized as a school that produces heroes of the world and its graduates are respected by the society.
- Garderobe in some incarnations of Mai-Otome functions as this. Healthy, normal young girls are brought in to be educated in both ettiquette and combat skills so that they may serve their patrons or nations as one woman armies. The latter part is due to technology rather than any inborn superpowers.
- Pretty Cure All Stars New Stage 2 introduced the Fairy Academy, which trained fairies for the opportunity to be mascots to future Pretty Cure.
- No points for guessing what My Hero Academia is about. The series focuses on U.A., one of many such academies in the setting. While it acts as a Superhero School for those aspiring to be pro heroes, it also has General Education, Hero Support, and Management courses taught so that non-pros can effectively navigate the setting post-graduation.
- The Hero Association in One-Punch Man serves to scout and rank heroes, coordinate their efforts by sending them to where they're most needed, as well as paying them for their efforts. Unfortunately, it leads to a lot of We ARE Struggling Together when heroes form their own cliques and actively jockey for position, not to mention being entirely incapable of recognizing King as a powerless figurehead.
- Beacon in Forged Destiny, as opposed to the one in RWBY which is just an Extranormal Institute, acts as this. It and its counterparts in the other kingoms train members of the Hero Caste to become Heroes capable of defending mankind against the forces of Grimm. Dropouts are regulated to the Soldier Caste, a group that is loyal to the kingdoms themselves rather than to mankind itself.
- The Stone Prince in Enchanted Forest Chronicles went to one of these.
- GameWorld: The Hero School used to train adventurers and knights, now it trains politicians and accountants (aka, the people who actually run the world nowadays).
- The Collegium in the Heralds of Valdemar series, at least for Herald-trainees. Students in other disciplines train there too, but for Heralds this is where they learn to master their Gifts (magical or psychic powers) and is the one place they can really call home.
- The Assassins' Guild School in the Discworld teaches its pupils to do some pretty extraordinary things - at the price of what is reputed to be a very high drop-out rate...
- The Institutes of The Mortal Instruments and The Infernal Devices teaches and trains its students to become Shadowhunters, the warriors who protect mundanes and keep them blissfully unaware of the Shadow World.
- Fable shows an academy called the Hero's Guild, as in the Fable Universe, Heroes gifted human beings that carry potential of carrying amazing combat skills with Melee, Ranged, and Magic abilities. Fully-trained Heroes in the Fable universe usually show extremely impressive skills in the area of combat they specialize.
- In Codename: Kids Next Door, when kids want to become Kids Next Door Operatives, they have to sign up for the KND Cadet Academy for training and studying on being a KND Operative. What separates it from a Military Academy is that, though KND is modeled as a military organization, as explained on the description above, it's as much of a society as it is a military group, which cause it to fit more into the Hero Academy trope.
