Outdoor Preschools: The "Forest School" Trend Explodes

Parents are increasingly trading bright plastic classrooms for mud, rain, and towering trees. The concept of “Forest School” or nature-based preschool has moved from a niche educational experiment to a mainstream movement across the United States. Driven by a desire for better health, resilience, and a disconnect from screens, this educational model is reshaping how we view early childhood development.

The Shift to Nature-Based Education

The premise of a forest school is radical in its simplicity: children spend the vast majority of their day outside, regardless of the weather. Unlike a traditional preschool with a scheduled recess, the outdoors is the classroom.

According to the Natural Start Alliance, the number of nature-based preschools in the United States more than doubled between 2017 and 2020, jumping from approximately 275 to nearly 600. This growth was accelerated by the COVID-19 pandemic, as parents sought safer, well-ventilated environments for their children. However, the momentum has continued because the results speak for themselves.

In these programs, children do not sit at desks. They count pinecones to learn math, track animal prints to learn biology, and navigate uneven terrain to build motor skills.

Washington State Leads the Licensing Charge

For years, a major barrier to the forest school movement was regulation. Most states require childcare facilities to have physical buildings with specific square footage, plumbing, and fire codes. This made it difficult for outdoor schools to operate full-day programs or accept state subsidies, effectively limiting these schools to wealthy families who could afford private tuition and partial-day schedules.

Washington State changed the game. In 2019, the Washington Department of Children, Youth, and Families (DCYF) became the first state agency in the country to permanently license outdoor preschools. This was a massive legislative victory. It meant that:

  • Outdoor schools could operate full-day programs.
  • Low-income families could use state subsidies to pay for nature-based education.
  • Standards regarding safety, sanitation, and ratios were specifically adapted for outdoor environments.

Other states, including Oregon and Colorado, have since begun looking at the Washington model to create their own licensing pathways, signaling a permanent shift in American education policy.

The Science of Resilience and "Risky Play"

The snippet provided mentions “boosting resilience,” and this is central to the forest school philosophy. A core component of the curriculum is something experts call “risky play.”

In a traditional setting, a teacher might stop a child from climbing a rock or jumping off a log due to liability fears. In a forest school, these activities are encouraged under supervision. Educators from established programs like the Fiddleheads Forest School in Seattle or the Cedarsong Nature School focus on teaching children how to assess risk themselves.

Benefits of Risky Play:

  • Confidence: Children learn the limits of their own bodies.
  • Executive Function: Navigating a slippery log requires focus, planning, and immediate decision-making.
  • Emotional Resilience: When a child falls in the mud, they learn to get up, brush off, and keep going rather than waiting for an adult to fix it.

Health Benefits: Beyond Fresh Air

The health arguments for outdoor school go beyond avoiding classroom germs. Pediatricians and researchers have noted several specific physiological benefits:

  1. Vision Health: Rates of myopia (nearsightedness) in children have skyrocketed. Studies suggest that exposure to bright outdoor light is crucial for healthy eye development and can slow the progression of nearsightedness.
  2. Motor Development: Walking on flat, carpeted floors does not challenge a child’s vestibular system. traversing uneven ground, roots, and rocks strengthens core muscles and improves balance.
  3. Immune System Diversity: According to the “hygiene hypothesis,” early exposure to diverse microbes in soil and nature helps train the immune system, potentially reducing allergies and asthma rates later in life.

Practical Logistics: Gear and Weather

A common question regarding these schools is: “What happens when it rains?” The forest school motto, borrowed from Scandinavia, is that “there is no such thing as bad weather, only bad clothing.”

Parents enrolling their children in programs like Tiny Trees (which operates in public parks) receive extensive gear lists. This is not about a simple raincoat. The requirement usually includes:

  • Base Layers: Merino wool or synthetic fabrics (never cotton) to wick moisture.
  • Mid Layers: Fleece for insulation.
  • Outer Shell: Heavy-duty waterproof gear from brands like Oaki, Reima, or Polarn O. Pyret.
  • Footwear: Insulated Bogs or similar neoprene boots rated for sub-freezing temperatures.

Schools do have safety protocols for extreme weather. High winds (risk of falling branches), lightning, or extreme cold thresholds will trigger a move to an emergency indoor shelter or a cancellation. However, for standard rain, snow, or cold, the class stays outside.

Frequently Asked Questions

Do children in forest schools learn to read and write? Yes, but the approach is different. Pre-literacy skills are taught through storytelling, identifying signs in nature, and drawing in the dirt or sand. Research shows that children who develop strong oral language and motor skills (needed to hold a pencil) in nature-based programs transition well to traditional kindergarten academics.

Is forest school more expensive than regular preschool? It varies. Because there is no building rent or maintenance, overhead is lower. However, safety ratios are strict. While a standard daycare might have one teacher for every ten students, forest schools often maintain a 1:4 or 1:5 ratio to ensure safety near water or during hiking. This labor cost often keeps tuition comparable to high-quality private preschools.

How do they handle bathroom breaks? This depends on the location. Schools located in state parks often use park facilities. Programs located on private land or in deep woods use portable camping toilets or teach children appropriate “nature potty” protocols, following Leave No Trace principles. Handwashing stations with warm water are standard requirements for licensing.

Is this safe for children with allergies? Outdoor schools can actually be beneficial for general immune health, but children with severe seasonal allergies or bee sting allergies require careful management. Schools carry EpiPens and staff are trained in wilderness first aid. Parents of children with severe environmental allergies should consult their pediatrician before enrolling.
