"Barnette and its progeny make clear that
any school district or state adopting a Pledge
of Allegiance policy or law should avoid
coercing participation and punishing refusal
to participate in any aspect of the flag ritual,
including, standing, saluting the flag, and
reciting the Pledge. Schools should consider
using permissive rather than mandatory language
to introduce the recitation of the
Pledge—“You may now stand to recite the
Pledge,” rather than, “Now we will all stand to
recite the Pledge.” Schools may require that
non-participants maintain order and decorum
appropriate to the school environment.
Schools may allow students choosing not to
participate in the Pledge to leave the classroom,
but they should not require them to do
so. By making participation voluntary, schools
not only will be avoiding First Amendment litigation,
but will also be teaching children that
tolerance of dissenting views does not threaten
American values, but rather strengthens
them."
