The District is comprised of 20 elementary schools, five middle schools, three high schools, four alternative schools, and one early childhood education center.
Community support for schools has always been strong in McKinney and residents consistently rate strong public schools as their top priority as the community continues to grow. A testament to this commitment to education was the most recent school bond election, held in 2005. Nearly 90 percent of voters supported the bond program that funded expansion of McKinney Boyd High School, one new middle school, four new elementary schools, and dedication of over $25 million towards technology over the next four years.
Schools in McKinney ISD have received recognition from the American Institute of Architects, School Planning and Management Magazine, the American Association of Administrators, the National School Boards Association and other prestigious organizations for innovative design and for being superior learning environments.
