About the Project

The 2019 Building Excellence V (BEX V) Capital Levy will fund a new replacement school building for Mercer International Middle School. It will also provide technology equipment and services, such as computers, peripherals, printers, and other technology for teaching and learning.

Interim Location: During construction, Mercer International Middle School will be located at the Van Asselt School Interim Site, 7201 Beacon Ave. S. An addition is being constructed at that location to convert it to a site large enough for temporary use by middle schools.
