How many times has Ash enrolled in Pokemon School? Throughout all the Pokemon TV series and movies, and anything else from the same canon/relevancy, what is the sum total of ashs enrollments in any kind of formal training regarding pokemon.
In the new-ish Sun &amp; Moon series Ash enrolls in Pokémon School, to my knowledge this is the only time he formally enrols into any school or long-term training program.



Other appearances of formal education in the anime include:


The Pokémon Trainers' School where Ash gives a guest lecture
Pokémon Ninja School where he goes to learn Jujutsu (which doesn't really directly apply to Pokémon)
Pokémon Tech where Jessie and James went to school
The Pokémon Summer Academy where Ash enrols in the Diamond &amp; Pearl era. I'd count it, but it's more of a summer camp / summer school thing that only lasts a week (or 4 episodes).
