Here in California it does a year or two going all out. Once you get it, you may or may not teach writing poetry. For the most part, don't expect to teach children to write poetry.
Most school administrators have nothing to do with that thought.
Their sophistry about their tensions and restrictions babble throughout society. What an opportunity to talk about responsible reporting, writing, storytelling, etc. In one case, a parent saw a teenager in a trenchcoat. That entire school was locked down as a precaution. The reactions are clearly because many school and security people are working with a heightened sense of awareness in the wake of last week's school tragedy.
