Thacher students use technology regularly in their daily lives. All dorm rooms have Internet and e-mail access, and students have their own personal folders on the School network where they can store data. Academic areas are wireless accessible. The Mudd Math-Science Building contains a computer lab as well as a media lab, where students can operate digital editing equipment for media and audio projects. Multimedia classrooms and laboratories allow teachers and students to integrate audio/visual presentations into daily classroom learning.

In the academic realm, students can pursue AP Computer Science, both the A and the AB course. This course uses the computer language Java and provides a good grounding in object-oriented programs with data structures and algorithms. This class is typically offered to juniors and some seniors. Students who complete this class may move to a post-AP level course called Java and Engineering, where they learn about Internet programming, which involves writing servlets and database applications. They also cover introductory artificial intelligence programming, as well as build and program autonomous vehicles and robotic devices.

Students can also learn about technology through their extracurricular endeavors. Those who choose to work on the School yearbook (El Archivero) or newspaper (The Thacher Notes) learn how to produce each publication entirely through digital technology. Other students may choose to join the Network Consultants, a group of five to ten students of mixed grade levels who help students and faculty with technology issues. The group also meets periodically to discuss campus technology issues and policies, and the Head Network Consultant sits on the Student Life Committee.
