It appears that there are no activities available for middle school or high school students, according to the school website:
At the time of writing, we checked with several sources who indicate that the website is simply not up to date. We are assured that the Director of Activities keeps a full slate of activities available to all ages, and even spends time at the school on most weekends maintaining this effort. On another note, “Day 6,” “Day 1,” “Day 2,” “Mini NESA,” and “Day 3” are not really student activities or athletics in the first place. Let’s hope that whoever maintains the website can add the appropriate information to reflect all of the activities that are available to students in each of the three schools.
It looks like there is a second calendar on the website (click here). This seems to confirm what our sources tell us: The Director of Activities is a very busy man. At least someone in building-level administration is a hard-worker.
