1. Preschool is an opportunity for growth.
It’s an opportunity to learn to share, follow instructions, and begin the foundation for learning that will occur in elementary school.
2. Preschool prepares children for kindergarten.
As kindergarten becomes more academic, many parents look to preschool to launch their child on the path to success in school. 
3. Preschool promotes social and emotional development
Young children learn social skills and emotional self-control through their experiences. Good teachers make time for those “teachable moments” when they can help children learn to manage frustrations or anger.
4. The preschool environment is structured, although it may not appear that way.
A highly structured environment helps young children learn to make friends and play well with others.
5. Children get to make choices.
Children have several choices of activities; a child who is wandering aimlessly is encouraged to choose one that interests him.
6. Children learn to take care of themselves and others.
Children’s sense of competence and self-worth grow as they learn to take care of themselves and help others. 
7. Preschool promotes language and cognitive skills.
Between the ages of 3 and 5, a child’s vocabulary grows from 900 to 2,500 words, and her sentences become longer and more complex.
