Most states prompt schools to teach about 9/11, but the details differ, AP finds

For three days in late summer, educators gathered at the Flight 93 National Memorial in rural Pennsylvania to discuss how best to teach 9/11 to future generations. Teaching about the 2001 terrorist attacks is now a priority for over one-third of U.S. states, though the specifics of how to approach the subject vary greatly. Some states have comprehensive guidelines, while others merely suggest a passing mention of the event.

A decade after the attacks, the majority of states no longer ignore 9/11 in their education standards, but the depth of coverage ranges from a brief mention to an extensive curriculum unit. State laws and education standards mandate or recommend 9/11 instruction in 25 states, with another 13 offering optional coverage. The ways states approach the topic do not always align with their political leanings.

For example, while states with conservative political climates tend to include discussions about balancing national security and civil liberties, states with more liberal policies also incorporate the 9/11 attacks into their social studies curriculum.
