No problem... I'm pretty short on time today, too.
I guess the short answer would be that the C of E would likely recognize the brown scapular as integral to the Christian faith, as it was an established tradition long before their split with Rome. You'd have to ask an Anglican Bishop for a more official ruling.
I question whether an exemption should be necessary, however. It is unusual to wear the scapular outside of clothing — the Pope doesn't. A scapular worn under clothing would not violate the school's policy. Insisting that it must be worn visibly would be an act of scrupulousness.
Have you worn a scapular for a long time? Unless it’s pinned, they end up creeping out. You see them constantly at my parish, and ladies adjusting them.
We have actual Scapular Medals. Our Lady of Mt. Carmel on one side, Sacred Heart on the other with our small chains attached to the slide.
But the problem with this is that someone could see it as simple jewelry. It’s not. I would have to get the exemption. It’s silly. If they allow headscarves, which ARE optional to Muslims.

“Further, unless one lives in a restrictive, theocratic country, wearing head scarves is optional. Many Muslim women also find it saves time to don a scarf rather than to style the hair. They argue that women who must spend so much time before a mirror each morning to style their hair are experiencing oppression by fashion dictates.”
