Your little one is growing up so fast! With each new developmental milestone, they become more independent and learn about the world around them. It's your job to further their progress—and that might include signing them up for a preschool program.

If you're considering enrollment in preschool, you likely have plenty of questions. Is your little one ready for this major transition? What's the typical preschool age range? And how much will your kid learn in a preschool classroom, anyways? We spoke with early childhood education experts to break down these questions and more.

What's the Typical Preschool Age Range?

Enrolling in preschool is a big decision, says Carolyn Rubenstein, Ph.D., a licensed psychologist from Boca Raton, Florida. The Centers for Disease Control and Prevention (CDC) defines the preschool age range is 3 to 5 years old. That said, most kids start preschool between ages 3 and 4. It's important to consider your child's unique readiness signs when making the decision, though preschool staff and your pediatrician can also weigh in.

If they're considering preschool enrollment, parents should check the guidelines set forth by certain schools. Some preschools take kids who will turn 3 years old during a certain point of the academic year (such as October 1 or December 1). Other preschools will take even younger children—sometimes as young as 18 months. That's why calling preschools in your area is a good first step for parents.

Is Your Child Ready for Preschool?

When deciding whether your child is prepared for preschool, you can't rely on their age alone. Some kids are ready earlier than others based on certain developmental components, and that's completely normal.

Here are some factors to consider regarding your child's readiness for preschool. Note, however, that your child might also be "preschool ready" without hitting every milestone on this list, especially if they have developmental delays. Your local school district should be able to help with the decision.

Potty Training. Some preschools have a requirement that your child is potty trained before attending. All kids have occasional accidents, but they should be able to use the toilet and clean up by themselves.

Nap Schedule. If your child is still taking long morning naps, they might not cope with the pace of a busy preschool classroom. Most all-day preschools will have a rest period after lunch, but the transition to preschool can be exhausting for little ones, and it's normal if they return home feeling very tired, especially at the beginning.

Separation Anxiety. Preschool teachers are experts at redirecting and cheering children up when they have to say goodbye to their parents, but your child should have some prior experience leaving you and being in the company of other adults before attending preschool.

Transitions and Routines. The preschool day is built around dependable routines and a pretty rigid schedule. "Up to 60% of a preschooler's day is spent in transition, like home to school, circle time to center time, center time to clean up, handwashing to snack time, inside to outside, and lunch to rest time are all times when a child is expected to stop one activity and pivot to another," says Donna Whittaker, vice president of curriculum and education at Big Blue Marble Academy, who has over 40 years of experience in early childhood education. Before starting preschool, your child should already understand how to move from one activity to another without becoming too overwhelmed or having a meltdown.

Communication. It's important that your child can communicate with adults and their peers when they start preschool. This means they can talk about their feelings and needs (for example, if they need to use the restroom or drink water).

Following Directions. Early educators are experts at getting children to follow directions and making everyday routines fun. However, your child should have prior experience following directions and instructions. If they have already attended a daycare, they should be well-versed in these skills.

Playing With Others. Before starting preschool, your child should also be able to play nicely with other kids. Their social skills don't need to be fine-tuned, but some comfort with peer interaction is still important.

The Benefits of Preschool

Preschool has many benefits for young children. "A preschool experience capitalizes on these incredibly formative years," says Allison Wilson, the senior director of curriculum and innovation at Stratford School, who has more than 20 years of experience in early childhood education. "Generally, a preschool program will provide academic foundations, such as the alphabet, numbers, shapes, and colors." Preschool can help children develop their language skills by exposing kids to new words and encouraging self-expression.

Social skills will also form as children participate in sharing, taking turns, lining up for activities, and following directions. "Children will learn how to function in a group setting, and how to be social beings in a social world," says Whittaker. "These social-emotional skills are beneficial because children will need them to work, learn, and play in a classroom."

These social benefits also include learning acceptance and celebrating diversity. "In a preschool setting, children might have the opportunity to work and play with peers that look different, speak another language, have varying abilities, and bring their perspectives to the classroom," says Whittaker.

Another benefit of preschool is that children are exposed to different people, toys, learning resources, and situations than they would encounter in their familiar home. As Whittaker explains, "Preschool settings will have materials that differ from home-type toys as they are created and purchased with learning goals in mind. In a well-stocked blocked center, a child can build to their full potential while learning math, engineering, geometry, measurement language, and problem-solving skills."

Finally, preschool help kids gain independence and confidence and to make new friends. This sets the foundation for a successful Kindergarten experience.

Preparing Your Child For Preschool

After enrolling your kid in preschool, you can help them prepare by encouraging independence and autonomy. Purchase a backpack and lunchbox they can open, plus clothing they can easily put on themselves. Have them practice socializing with other kids at the park, at birthday parties, in playgroups, or on play dates. Get them acquainted with early skills like counting.

Wilson also suggests preparing for preschool the following ways:

  • Visit the school
  • Read books about starting preschool
  • Practice some simple self-help skills (asking the teacher for help, taking shoes on and off, washing hands)
  • Engage in pretend play to explore the concept of preschool (sharing, playing with others, etc.)

It's normal for both parents and kids to feel a little apprehensive about big changes. Take time to celebrate this transition as preschool represents an exciting time in your little one's life and their introduction to formal education.
