Along with a fee, OWL participation includes parents signing up to set up, clean up after an OWL session, copying or prep materials or buy snack etc. We see this taking 1-2 hours. Sign up genius will be created in the fall for parents to sign up (separate volunteer hours are required for each child participating).
Children are also expected to have regular attendance during OWL unless in cases of illness, emergency or already prearranged absences.
