No, you just need to keep doing it until they level up.
The explaination of the mechanics I saw is that the chance of levelling starts out fairly low, and goes up every time you complete the mission. So, you might
get lucky and have someone level quickly, or you might be unlucky and have it take forever.
One reason why it's a very good idea to get the theme that doubles your chance of levelling allies in season 1... you have to level a fair number of them
for the season 2+ rank exams. I was stuck as a chunin for an annoying length of time this season because people wouldn't level...
