Although perfect attendance is the goal, it’s not always possible. School districts are required to excuse a student’s absence for reasons listed in state law, such as to:

• Observe a religious holy day
• Attend a required court appearance 
• Serve as an election clerk
• Appear at a governmental office to complete paperwork required in connection with the student's application for U.S. citizenship
• Take part in a U.S. naturalization oath ceremony
• Sound "Taps" at a military honors funeral held in Texas for a deceased veteran (grades 6-12 are eligible)
• Attend a healthcare appointment (student must return to school on the same day of appointment)
• Visit college campuses (juniors and seniors)

The Texas Education Code describes these reasons in greater detail and lists additional statutorily excused absences.
