MIAMI, Fla. -

It's been nearly 10 years since federal officials recommended mental health screenings for students.

However, with no requirements, an Associated Press national review shows there's a fractured approach among schools.

State to state, there is no consistency with whether schools actually screen students' mental health, what age at which they're screened, for what they're screened, or what treatments are used.

We're told the federal government does not keep track of school mental health screenings, so it's impossible to say how many states do or don't offer tests.

Because problems typically start during adolescence, if left untreated they can lead to substance abuse, school drop-outs, and difficulty maintaining steady jobs.
