About Us

Cass Technical High School celebrates over 100 years of Excellence in Public Education!

We continue to prepare students to pursue their goals and fulfill their highest destinies.  Unquestionably, our new building, which has earned several architectural awards, serves as a catalyst toward sustaining and strengthening our status as a progressive and educationally-efficient institution.  These recognitions join our existing distinctions of being twice recognized as a “Blue Ribbon School” by the U.S. Department of Education, twice recognized as one of America’s Best High Schools as featured in Redbook Magazine, earned the title of being a “Grammy” Signature High School,” and named a “Demonstration School” by NABSE (National Alliance of Black School Educators).

Other notable accomplishments that add to our enviable record of excellence in public education include being selected for National ACT/Education Trust Study, awarded the   Green Flag by the US Department of Environmental Justice of IPM Implementation, honored twice as a recipient of Michigan’s Governors Cup and the National Excellence in Education Awards, and cited by U.S. News and World Report as an Outstanding School and awarded a Bronze Medal for 2009.  Additionally, we have earned numerous yearly academic and curriculum awards:  8 Merit Finalist and 13 Achievement Finalist in the last six years, 1st Place Coca Cola Art Award for 3 consecutive years, 6 consecutive years of our Architecture students chosen for Charettes, 10 consecutive years of National Art Awards, 13 consecutive years National Academic Games Awards, 14 consecutive years of Grand Awards at Metro Science and Engineering Fair, and our students earned 16  Bill and Melinda Gates Millennium Scholarships in the last five years!


School of the Week: Cass Technical High School

Posted on January 12, 2015

An International Baccalaureate World School

For the first 10 years of her academic career, LoReal Harris attended a private school. Her prekindergarten through eighth grade years were paid for out of pocket by her mother, Annie Blackmon.

“Every single month, my mom paid tuition for 10 years… wow. That’s a lot of money,” recalls Harris, who is now a 17-year-old high school senior. “My mom instilled in me at a very young age the importance of education. My mom always told me, ‘You will not have a job, you will have a career.’ And the way to achieve this is to excel academically.”

For her daughter’s high school career, Ms. Blackmon decided to switch gears from private schooling to public and placed her trust in Cass Technical High School.

Cass Tech is one of Detroit Public Schools’ premier application schools. The newly authorized International Baccalaureate World School – the first school in the city of Detroit to earn this designation – is a two-time, nationally-recognized School of Excellence ranked in the top 5% of all high schools in the state by the Michigan Department of Education; a top-10 ranked high school by the Mackinac Policy Conference; and is ranked as one of the best high schools in the country by U.S. News and World Report.

Needless to say, Ms. Blackmon made the right choice. And her decision has paid off – literally.

Thanks to Cass Tech’s notable Dual Enrollment Program with Wayne County Community College District – the largest program of its kind across the city that allows students to earn college credits while in high school – Harris will walk in two commencement ceremonies in the spring. In May, she will graduate from WCCCD with her associate’s degree. In June, she will accept her high school diploma.

“Technically, I’ll be a college graduate before I graduate from high school!” says Harris, who plans to study pre-law at the University of Toledo in the fall. “I’ve always wanted to pay my mom back somehow for all that she’s given me. Now, I kind of get the chance to do just that.”

What exactly does this mean for mom and Harris?

  • Two years of college tuition that she will not have to pay for because Harris will enter the University of Toledo as a junior in the fall;
  • A tuition-free undergraduate degree as Harris has already secured scholarships to cover the final two years;
  • Graduating in two years with a bachelor’s degree, as opposed to four; and
  • Starting and potentially completing law school two years earlier than her peers.

“Cass Tech: No. 1. Second to None.”

There are dozens of similar success stories at Cass. Students like Harris are the norm, says Principal Lisa Phillips, which is why students, staff and alums frequently share the popular slogan: “Cass Tech: No 1. Second to None.”
