Alternative paths exist if you already have a degree in another field. Many states offer lateral entry programs that allow you to teach while completing certification requirements. For postsecondary roles, industry experience in fields like engineering or data science can sometimes substitute for formal education credentials, particularly at technical colleges or vocational schools.

Develop both technical proficiency in subjects like algebra, trigonometry, and statistics, and soft skills like clear communication and patience. Practice explaining complex problems through tutoring or peer mentoring. Join math clubs or volunteer as a teaching assistant to build these abilities. Coursework in child psychology, classroom management, and educational technology will prepare you for real-world teaching environments.

Secondary teachers need state certification, which usually involves passing exams like the Praxis Mathematics test. While postsecondary positions don’t require licensure, certifications in specialized areas like statistics or applied mathematics can strengthen your resume. Gain classroom experience through student teaching placements or substitute teaching roles—many degree programs include a semester-long practicum. Entry-level positions at community colleges may accept teaching assistantships or adjunct roles as sufficient experience.

Plan for at least four years to complete a bachelor’s degree, plus one to two additional years for certification or a master’s program. Full-time PhD programs typically take four to six years beyond undergraduate studies. Balancing coursework with hands-on practice through internships or part-time teaching roles will help you build the necessary skills efficiently.
