    Welcome to Diamond!
    Welcome to William Diamond Middle School’s website. One of two middle schools in Lexington, Diamond offers a rich and interesting program of study in traditional academic subjects, physical education, the arts, and technology. We serve about 850 students in grades 6, 7 and 8. We are proud to participate in the METCO Program, welcoming students from Boston as well as Lexington into our Diamond community.

    This website is designed to give you access to a range of information about Diamond, and about your child’s current and future experiences here. Among other things, you will find information about departments and courses, and links to teacher web pages, as well as information about clubs and activities.
