Mr. Coxe examined The "Steigerschulen", which were secondary technical institutes, while studying mining engineering in that country.
[3] Twenty-nine male applicants, ranging in age from 12 to 24 walked into a small two-story building in Drifton, PA, seeking an education.
They studied spelling, reading, writing, grammar, composition, algebra, bookkeeping, geometry, trigonometry, mechanical drawing, physics, chemistry, mineralogy, drafting, mining, and other courses.
Within five weeks, the board of directors decided to lease eight more rooms in another building to accommodate increasing enrollment.
In 1914, Mrs. Coxe funded the construction of the rear wing of the existing building, which housed the chemistry and physics laboratories.
The night school briefly reopened between 1940 and 1950, but after World War II, it was closed again for lack of enrollment.
The Century II Building, containing the cafetorium, computerized library, science labs, and modern classrooms, opened in 1979.
In 1999, work began on a $4.6 million expansion project that added a new Science/Technology wing and a new Athletic and Drama Complex.
The building project was funded through a bond issue secured through the Hazleton Industrial Development Authority, as well as private donations.
This project marked the largest, single private investment made in the local area at that time.
In 2009, MMI announced its plans to build a $3 million privately funded sports complex on 29.5 acres (11.9 ha) of undeveloped land in Foster Township.
The complex, which consists of high school regulation-size baseball, softball and soccer grass turf fields as well as several nature trails that also serve as cross country courses,[8] was completed in 2011, and was used for sports games beginning in the 2011-2012 school year.
[9] Every core course offered at MMI holds the Honors distinction, demonstrating the coursework is in-depth and comprehensive.
In addition, MMI offers multiple Advanced Placement courses designed to prepare students for college-level classes.
