North Bay History Day
National History Day engages students through authentic historical inquiry on a topic of their choice, fostering the amplification of the diverse voices of our past. North Bay History Day (Sonoma, Marin, and neighboring counties) connects students to local, national, and global history by engaging them in discovering how the historical, cultural, and social significance of the past is relevant. All resources available on the NHDCA.org website are free for any teacher to use with their students.
Student research, analysis, and interpretations are brought together to become their final projects, which may be displayed at school showcases. Student projects may be entered at the North Bay History Day contest, and winners at North Bay History Day advance to the state History Day competition.
