Project TND has been rigorously tested. More than 5,700 youth
from 42 high schools in Southern California, and over 2,800 youth
from 45 high schools outside of California across the U.S., have
participated in our research on the program. We have evaluated program effectiveness in
alternative (continuation) high schools as well as regular high schools.
The student populations in these schools have been ethnically diverse,
including African American (5-26%), Latino/Hispanic (28-46%), Asian
(1-7%) and White (36-45%) students.
To date, we have conducted six randomized experimental studies in which schools that received the program were compared to schools that did not receive the program.
