    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 920 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. We hope that you find it informative and easy to use. Welcome to Diamond!

    Annual Team T-Shirt Sale

    To commemorate the 2018-2019 school year, we are starting our annual Team T-Shirt Sales event. Each T-shirt will display our Diamond DRUM logo on the back and a student-designed team logo on the front and sleeve. Samples of each design are available with team teachers.

    We hope all of our Diamond community will participate. There are many activities in the spring for teams to come together and wear their Diamond shirts. Eighth graders are also encouraged to participate, especially so they can wear them for upcoming year-end trips to DC, Quebec, and Canobie Lake, as well as on local field trips.

    T-shirts are $11.00 each and can be purchased at the Diamond PTA online store, available by logging into your MySchoolAnywhere account.  Please note that all sizes are adult sizes: Small, Medium, Large or X-Large.
