Which of the following is NOT a requirement for EMS certification in Texas?

The requirement for EMS certification in Texas does not include a condition stating that candidates must be at least 21 years of age. In fact, the minimum age requirement is typically 18 years old for EMT certification. This means that individuals who are 18 years old can apply for certification once they have completed the necessary training and examinations.

In contrast, the other options presented are indeed requirements for certification. Candidates must complete the jurisprudence exam to demonstrate their understanding of relevant laws and regulations. Additionally, successful completion of a Department of State Health Services (DSHS) approved course ensures that candidates have received proper training in emergency medical services. Finally, having a high school diploma or its equivalent is usually a prerequisite, ensuring that candidates have a basic educational background before undertaking the responsibilities of an EMT.
