How to Become a Biology Teacher in Texas

If you’re passionate about biology and education, becoming a biology teacher in Texas offers an exceptional career path with abundant opportunities. The Lone Star State’s growing student population and strong emphasis on quality education create the perfect environment for aspiring educators to thrive and make a meaningful impact.

The demand for qualified teachers in Texas, especially in STEM fields like biology, is substantial and growing. The Texas Education Agency projects adding 68,000 elementary and 65,000 middle school teaching positions in the next decade, with science subjects among the highest-need areas. This growing demand creates promising opportunities for aspiring and current educators. Teachers in Texas can look forward to several key advantages:

  • Strong job market with competitive salaries and benefits in Texas’s robust economy (second largest in the U.S.)
  • Supportive teaching communities and professional development opportunities
  • Significant job security due to growing student enrollment (19% increase over the last decade)
  • A diverse cultural environment that welcomes educators from all backgrounds

As a biology teacher, you’ll do more than teach science concepts; you’ll inspire the next generation of scientists, healthcare professionals, and informed citizens. Your guidance will help students understand the natural world and prepare them for future opportunities in rapidly expanding STEM fields.

  1. Obtain a Bachelor’s Degree: Earn a bachelor’s degree from an accredited college or university, ideally with a major in biology or a related science field. You’ll need a minimum GPA of 2.5 to qualify for most educator preparation programs.
  2. Apply to an Educator Preparation Program (EPP):  Choose and enroll in an approved EPP, such as TeacherBuilder’s online alternative certification program. Submit your official transcripts for review and select Life Science (7-12) as your certification area.
  3. Complete Required Training and Field Experience: Engage in self-paced, competency-based coursework through your chosen program. You must also complete at least 50 hours of field-based experience, which provides hands-on classroom exposure through activities like small group instruction and lesson planning.
  4. Pass Certification Exams: Prepare for and pass the TExES Life Science (7-12) Content Exam (238) and the Pedagogy and Professional Responsibilities (PPR) Exam (160). These exams are required specifically for biology teacher certification in Texas.
  5. Apply for State Certification and Complete Background Check: Once all requirements are met, submit your application for certification to the Texas Education Agency. You’ll also need to complete fingerprinting as part of a national criminal background check, which is mandatory for all first-time applicants

Certification Exams and Preparation Tips for Aspiring Biology Teachers

As you progress through your journey to become a biology teacher in Texas, certification exams represent a critical milestone. For biology teachers, you’ll need to pass two key exams: the TExES Life Science (7-12) Content Exam (238) and the Pedagogy and Professional Responsibilities (PPR) Exam (160).

The Life Science Content Exam evaluates your knowledge of biology concepts, laboratory practices, and science teaching methodologies. This exam ensures you possess the subject-matter expertise necessary to effectively teach biology to secondary students. Meanwhile, the PPR Exam assesses your understanding of teaching principles and practices across four domains:

  • Designing Instruction and Assessment to Promote Student Learning (34%)
  • Creating a Positive, Productive Classroom Environment (13%)
  • Implementing Effective, Responsive Instruction and Assessment (33%)
  • Fulfilling Professional Roles and Responsibilities (20%)

The PPR exam consists of 100 selected-response questions and allows 5 hours for completion, reflecting its comprehensive nature.

Preparation Strategies for Success

Effective exam preparation is essential for certification success. Most Educator Preparation Programs provide test preparation materials upon enrollment. To maximize your chances of passing on the first attempt:

  • Utilize all test preparation resources provided by your EPP
  • Form study groups with fellow candidates to share insights and strategies
  • Practice regularly with sample questions to familiarize yourself with the exam format
  • Create a study schedule that allocates time for both content knowledge and pedagogical concepts
  • Take advantage of free test preparation materials that may be available through your program

Remember that success on these exams requires mastery of both biology content knowledge and effective teaching strategies. While your science background provides the foundation for the content exam, developing strong pedagogical skills is equally important for both your certification exams and your future classroom success.
