Before I begin, let me point out that my problem with how they handled Wesley Crusher is not with the concept of a commissioned officer still in his teens. Personally, I believe it was designed to show that like in most of the cultures on this planet, by the 24th century society, if not the law, sees people fifteen and older basically as adults. My problem is how they handled this specific character.
1. How he got his brevet appointment in the first place.
At first when I was ten and I saw "Where No Man Has Gone Before", I thought it was cool. I'm an adult now and I think "wait a second. The Traveler has basically admitted that he was lying his way into Starfleet's confidence so he could use them as a cheap source of transportation and to indulge his curiosity, and you still grant someone a field commission to even an acting Ensign on his recommendation? No, he should've earned that rank himself. Let him prove his abilities in a situation during a crisis i.e. like he mans a station and remains cool during a battle or other crisis. Or have him foil a plot against the ship on his own initiative. That would've been a better story.
2. Ignoring His Input or opinions
If you trust someone enough to give him/her a provisional officer's rank, shouldn't you give that man or woman the respect you give the other commissioned officers in his or her grade and listen to their reports and not automatically dismiss them. They should've at least stopped to listen when he tried to warn them about Lore masquerading as Data and talking with the Crystalline Entity.
3. Make his rank official and still send him to the Academy.
What was the point of giving him a full Starfleet commission as an ensign on the command track, complete with the red uniform, and still sending him to the Academy? If he's already proven he can do the job enough to formally make him an officer, there's no point.
