The Mentoring Initiative was created to address challenges faced by urban youth. Such challenges include alcohol and/or drug abuse, teen pregnancy, educational failure, gangs, and violence. The average cost per youth participant in a mentor program is $315 annually. There are currently 65,000 to 70,000 mentors providing support to these historically underserved youth through 139 mentor programs. However, there are 78,000 youths on waiting lists for mentor program participation, and it is anticipated that current mentor programs will experience an average increase of 12.5 percent in their participation rates over the next 12 months. Mentoring programs have proven themselves to be logical, cost-effective methods of assisting today's historically underserved youth in becoming productive, contributing members of our society. Studies document the powerful impact of a caring adult in a young person's life. A study of Big Brother/Big Sister programs involving 1,482 young people ranging in age from 8 years to 17 years found a 46 percent reduction in the initiation of drug use and a 27 percent reduction in the initiation of alcohol use. Additionally, a study of 546 youths participating in the Youth Free Program found that grades in school improved for 59 percent of the students as a result of help received from mentors. Further research conducted with 387 youths participating in the Give a Little, Get a Lot program shows 53 percent of youth participants credited their mentors with improving their ability to avoid drugs. A study conducted with 584 youths participating in the Friends Now program shows 62 percent of the program participants believe they had improved their ability to stay out of trouble as a result of their mentoring experience.

 According to the information above, which mentor program had the greatest impact on improving the school grades of its youth participants?

According to the information above, if the number of youths on waiting lists for mentor programs was equally divided among current mentor programs, what proportion of waiting youths would each of the mentor programs service?
