For younger children, it is usually best for them to be accompanied by a parent, guardian, or trusted adult when going to and from school. This ensures their safety and well-being. As children get older and more responsible, and if their school is within a safe and familiar neighborhood, parents may gradually give them more independence to walk or bike to school on their own.
However, it's important to assess the child's maturity level, the safety of the route they will take, and any potential risks before allowing them to go to school alone. It is also important to establish clear rules and guidelines and to talk to your child about safety precautions they should take while walking or biking to school.
