It’s never too early or too late for a parent to become a teacher. In this age of teacher accountability, endless school testing, increased pressure and competition, and the proliferation of "educational" toys, too many people forget that success begins at home.

Freeman A. Hrabowski Ⅲ, president of the University of Maryland, Baltimore County, and co-author of Beating the Odds: Raising Academically Successful African American Males and Overcoming the Odds: Raising Academically Successful African American Young Women, says that in the interviews he and his co-authors conducted, the overwhelming factor in their children’s academic achievement was that parents inspired and envisioned their children’s success. They thought and talked about what would be required to have a .successful child.

"It just makes such a difference when there’s someone in that house working to relate to that child and inspire that child," Hrabowski says. "These parents (of the high achievers discussed) are really inspirational in their commitment to their children."

Professor Barbara T. Bowman, one of the faculty founders of Chicago’s Erikson Institute, an independent institution of higher education that prepares child development professionals for leader- ship, says that Black children must learn in two different cultures-the African-American culture in which they live and the mainstream culture on which school and education are based.

Bowman also says the relationship between children and their parents is critical. "It is the early responsive ness of the caregiver to the infant’s behavior that creates a sense of well-being and optimism that affects the child’s interest in learning," says Bowman, who served as president of the institute from 1994 to last year. "Children who like and want to please the adult learn better what the adult wants them to learn."

In this day of highly competitive testing and the stress of getting high SAT or ACT scores, it’s important also to avoid pressuring or overexposing your child. Your son or daughter is probably already facing stress at school and on the playground. Your role is to help him or her relieve and manage that stress. Help them to understand that life does not end or begin with a test. And while academic success is important, it’s also important to keep everything in perspective. Failure is a relative term in the grand scheme of things. If your child did poorly on a test, but answered a particularly tough question correctly, stress the positive. On the other hand, if schoolwork comes too easily to your child, find other ways to challenge him or her so they understand that life won’t always be that way.
