STEM Course Pathways

Mater Dei’s Science and Math Departments offer a wide variety of STEM courses to meet students’ individual needs and interests. All Science and all Math courses include STEM projects to prepare students for success in college and future careers in both STEM and non-STEM fields. Additionally, students with an interest in STEM can choose to participate in the STEM electives along with their Science and Math courses.

We have designed the following sample pathways to help students plan their progression through STEM courses at Mater Dei:

Animals (e.g. Zoology or Veterinary)
Aviation
Chemistry
Coding and Computer Science
Crime Scene Investigation or Criminal Law
Engineering
Environmental Science
Marine Biology
Medical
Physical Science

The pathways are considered samples- we can plan unique course progressions for students with different needs and interests.

Most students take one Math and one Science course per year and courses cannot be taken twice.
