Starting between the ages of 2 1/2 and 3, you will have the option of placing your child in preschool. Some parents may ask, "Why preschool? Isn't my child learning enough at home or with a caregiver?" Of course nothing takes the place of a nurturing and loving home, and no one is more important to children than their parents. But research shows that kids who attend quality preschool have higher math and reading skills, are better prepared for kindergarten, behave better in class, and are more likely to graduate from high school and go to college.
