  <p>As for your student, there's no rule that you are not allowed to simultaneously move two pieces at once, and since <a href="https://www.fide.com/fide/handbook.html?id=208&amp;view=article" rel="nofollow noreferrer">the rules</a> do not describe exactly <em>how</em> the king and rook reach their final squares, this is up to the player.

  That's actually illegal:

  As for your student, there's no rule that you are not allowed to simultaneously move two pieces at once, and since [the rules](https://www.fide.com/fide/handbook.html?id=208&view=article) do not describe exactly *how* the king and rook reach their final squares, this is up to the player. In any case, this is *not* a violation of rule 4.4.2:
  
  > 4.4.2 [If a player having the move:] deliberately touches a rook and then his king he is not allowed to castle on that side on that move and the situation shall be governed by Article 4.3.1
