In Texas, you generally need more than just a bachelor's degree to teach elementary school. While a bachelor's degree is a requirement, you'll also need to complete a teacher certification program. This usually involves passing the required teacher certification exams (like the TExES exams), completing student teaching, and possibly additional coursework depending on your specific degree and chosen certification path.
Therefore, a bachelor's degree alone is insufficient to qualify you for a teaching position in Texas elementary schools. You need to pursue and obtain the appropriate teaching certification. Check the Texas Education Agency (TEA) website for the most up-to-date and specific requirements.
