This research brief details six programs that have been shown through careful evaluation to either delay sex, improve contraceptive use, and/or reduce teen pregnancy. Some of the programs were designed specifically for Latino teens and some were not; those that were not designed specifically for Latinos included Latino teens as part of the program evaluation or were found to be particularly effective among Latino teens. Four promising programs—those that have not been as rigorously evaluated but have shown some encouraging results—are also briefly discussed. This list of programs is a starting point for those interested in helping Latino teens avoid too-early pregnancy and parenthood. More effective programs designed specifically for Latino youth are needed as are additional strategies for reaching parents, families, policy makers, and other community leaders.
