San Juan Academy has developed a unique approach to dealing with underachieving students.

Instead of doling out punishment for incomplete assignments, or assigning extra hours of tutoring for bad grades, the academy provides failing students with a reward. Through the Computers for Success program, San Juan Academy students who fall behind their classmates in reading and mathematics are given their own computers. For nine weeks, the students get to keep a personal computer with a printer and software in their homes. They can work and play with the computer whenever they like and as often as they like.

Is this a prize for being bad in school？ "It may look that way to an outsider," says school principal Edna Seymour, "but this approach is actually well backed up by research. Studies show that students who are computer literate do much better in school. The figures rise for students who actually have a computer at home, and are even higher for students from homes where most of the family members are comfortable using a computer."

Because of this, when a student is given a computer to take home, families are encouraged to get into the act, too. Students in the Computers for Success program are required, together with their parents and siblings, to attend a weekend computer seminar. This way everyone in the family becomes familiar with the use of the computer. This is an investment in the students' educational future. "It is widely accepted that parental involvement makes all the difference in a child's school success," says Principal Seymour. "We are extending that idea to involve families in our computer literacy program. As part of that program, we make it possible for families to buy refurbished computers at an affordable price. Many of our families have already taken advantage of this opportunity. On the whole, we have been very pleased with the Computers for Success program."
