Please don't take this wrong, yet I think you left "in which" out of the thread title.
Public School Districts don't raise teenagers.
Families (especially parents) and Neighborhoods have a chance at so doing.
And even that statement isn't exactly correct.

I only say this because I worked at an education and training facility for "at-risk" youth for a number of years.
The youths that "slipped through the cracks" of regular, Public Education.

The job was rewarding and challenging.
Attempting to fix other peoples' mistakes usually is.

A teenager is essentially already raised . . . The challenge is to direct the individual in a positive direction in every sense of the word positive.
No Public School District can be expected to achieve that goal.
In fact, there is no 100% effective answer to the implied question posed.
