Nearly 10-years ago federal health officials recommended universal mental health screenings for students, but according to an Associated Press review, there are no requirements to provide services.
Screenings vary widely from state to state and within school district.
There's no consistency on whether schools screen, what age they screen, or what they screen for.
Treatments also vary.
Some experts worry mass screenings will over-diagnose students.
Health experts say mental health problems typically start during adolescence.
If un-treated, it can lead to substance abuse, school drop outs, and difficulty maintaining steady jobs and relationships.
