To age Teen Townies use similar steps to creating a household with neighborhood Sims in the college screen. Because Teen Townies cannot use the phone to apply for scholarships, they come only 500 in their pocket.
Teen Townies do not have to go through college if you do not want them to. Have them move into a dorm, and then use the phone to drop out of college. Or if they have an adult friend in the neighborhood, go to that friend's house and invite the Townie to move in. If the Sim inviting the Townie, graduated from college, the Townie will also be considered a college graduate.
