Activist teachers formed a national committee and prevailed on the National Education Association to adopt a resolution of endorsement. Thus was conceived the BLM at School National Week of Action, to be held annually the first week of February to set the tone for Black History Month. The following year, school districts in more than 20 major cities, including New York, Chicago, Los Angeles, Washington, D.C., Boston, and Seattle incorporated BLM at School Week into their curricula.
