Sarah Arndt

Welcome to Aledo High School! My name is Sarah Arndt and I have been teaching high school science for the last 7 years. I have had the pleasure of being able to teach Human Anatomy Physiology, Earth Science, and Biology in the past. This is my first year with Aledo ISD, and I am so excited to join the community! I currently teach AP Biology and Forensic Science. I enjoy coming to work each and every day... and am blessed to be in such a fantastic school district. I'm energetic, patient, and willing to help each student reach their goals in our school. I can be reached at the following e-mail address: (please allow for 24hrs response time), or I can be reached by calling the school at 817-441-8711. I am available for tutorials/help during Flex period. Students need to schedule a time with me if they wish to meet before or after school. I look forward to a fantastic school year!

I use CANVAS as a way to communicate with each student .Please be checking parent Ascender portal, at least weekly, so that you are aware of the grades and progress they are making in every class they are in.
