YES, WES takes 6th grade applicants.
The school is N-8. I know several people who have entered in 5th or 6th.
It is a religious school, but not directly associated with a parish, and has students from all types of faiths. It is worth a look. I mention it based on the description of your child.
Not sure what the hahaha is directed at, but I am happy to answer any questions you may have about the school.
Look at the 8th grade placements…see if you recognize any schools you would consider for high school for your child….the school has worked for our children and our entire family.
