Each existing JEM has a minimum of six and a maximum of 11 students in the same grade who live within either the West San Fernando Valley or the Conejo Valley. If there is room in a JEM, your child my join. When a JEM reaches 12 students, it splits into two separate JEMS and another host is identified.  

A minimum of six students in the same grade within a geographic area are needed to start a new JEM. Typically, a few families will recruit their friends and together with other parents who inquire through the education department, a new JEM can be formed.
