Perhaps the best known of these is astronomer and computer security expert Clifford Stoll. The curriculum has been revamped and expanded continuously over the second half of the 20th century, for entrance into schools of engineering and or the training of technicians for entry-level positions in current technical fields. The programs the school now offers includes bio-chemical technology, computer technology, and engineering technology. Instruction in electricity and electronics is also provided. Hutch-Tech also offers a selection of college prep courses including Advanced Placement that both helped their major, and helped them meet their general education requirements that most colleges require. The courses include AP English Language and Composition, AP English Literature and Composition, AP Biology, AP Chemistry, AP Calculus, AP Spanish Language, AP Physics-C, and AP United States History.

The renovation took place from the summer of 2005 until the summer of 2007. The "New" building has more and updated classrooms with Promethean Ltd smart boards, a brand new gymnasium, new engineering and electrical equipment, and new science rooms. While the building was being renovated, school operations took place at Kensington High School on the city's East Side. At the end of the 2010 School Year, David Greco retired after nearly fifteen years of service as head administrator at Hutch-Tech, and nearly twenty-five years as a history teacher, and administrator elsewhere, including Bennett High School, Buffalo Traditional, and others. This is five years later than his original retirement date of 2005, but Greco made a promise to see the renovations through, and see the students back to the building on South Elmwood. Greco's successor was Sabatino Cimato. In November 2015, Sabatino Cimato was appointed to associate superintendent in charge of leadership for Buffalo Public Schools. Dr. Gabrielle Morquecho was named interim principal for the remainder of the school year. In July 2016, Dr. Morquecho was appointed Principal of Hutch-Tech.
