What are Nature and Environment Schools?

The Finnish Association of Nature and Environment Schools organizes and develops LYKE-network. The network offers environmental education services for schools and kindergartens on local level. It also promotes nature and environmental education in Finland. LYKE-network consists of centers governed by municipalities, governmental organizations, enterprises, and associations.

Our aims and means:

  • We are developing and expanding the LYKE-network, which enables different groups of children and youth to participate in high-quality nature and environmental school activities with their teachers and instructors.
  • We maintain the service so that more and more educators can find materials and services to support their environmental education work.
  • We provide training for educators so that more and more of them are prepared to carry out environmental education. The largest of the training events is a major Out-Ut-Out event developed in collaboration with six other partners of cooperation.
  • We give support to the members of LYKE-network, deliver good practices from professional to professional and help in co-operation with municipalities and schools.

There have been Nature Schools in Finland for over 30 years. Today there are 57 centers in the network. The resources for building the network has come from the Ministry of Environment and
the Ministry of Education and Culture. 

What does LYKE-network do?

The centers in LYKE-network work mainly with schools and kindergartens. The customers get help from the experts of LYKE-network for their daily job with pupils in the field of environmental education.

  • The day programs and trainings are based on the national core curriculum of compulsory education.
  • Learning is experimental, experience-based, hands-on learning in authentic learning environments.
  • The final goal is that every kindergarten and school in Finland have a possibility to get professional help with their environmental education from LYKE-network.


There is active quality work for constantly improving service that LYKE-centers provide. Each branch of the network develops their quality locally. The Finnish Association of Nature organizes the development work of collective quality criteria with the centers. The aim of the criteria is to maintain and improve the quality of the environmental education services. It also gives a certificate to the centers, which help centers to communicate about their quality work to the customers. There are two levels of certificate in the LYKE-network. LYKE Activity Center is the basic level, whereas LYKE Development Center is the highest level of certification.

The application process starts with self-auditing of the center. The Board of The Finnish Association of Nature and Environment Schools accepts the new members to LYKE-network. System of peer-auditing frequently verifies the meeting of the criteria.  During peer-auditing, staff members from a certified LYKE-center visit a predetermined peer center, where they go through the auditing procedure, which enables reciprocal development, learning from each other and sharing good practice.
