We identify three eras in the history of special education: Early Reform (1800 – 1870), Stagnation and Regression (1870-1950), and Contemporary Reform (1950 – present). Next we examine parallels between eras and consider implications for people with disabilities today, highlighting the importance of the systematic study of historical perspectives in preparation programs for special educators.
