Our school belongs to the Cheshunt Extended Schools Service (ChExs). They run a range of courses for parents and after school activities for children at schools in their consortium area. They publish a booklet with details of available activities which is distributed to parents and also regularly send out flyers advertising activities. Some of the activities that they regularly run at our school are Art & Craft sessions.
