Upsan is correct that if you want to prepare for theological seminary (which is all graduate level degrees), most bachelor's degrees will be sufficient for admission to a seminary if the GPA is good enough.
In most churches, degrees, especially seminary, are needed for ordination and employment as a minister. There are exceptions.
As for youth ministers...like JSF said, not all youth ministers have specific theological and ministry training, but it gives a candidate an advantage if they have a degree in ministry.
Some undergraduate schools have bachelor degrees in ministry related fields, including youth ministry specializations. Maybe this is what Kendall is wanting to pursue. Or maybe he's involved in a church in Georgia where he can get on the job training.
It's possible for someone to prepare for ministry while at Ohio University, but if somebody wants to start taking related courses on the undergraduate level, you can't do it.
