I think you're misremembering there.

Wakka: There's a room in there called the Cloister of Trials. Beyond is where the apprentice summoner prays. If the prayer is heard, the apprentice becomes a fully-fledged summoner, remember?

Apprentice Summoner - Learns about the Summoner Arts
Summoner - Successfully receives at least 1 Aeon
High Summoner - Defeats Sin with Final Aeon

They never go into it but I bet there have been at least a couple Summoners who got Final Aeons that weren't strong enough and they died fighting Sin.
