Electronics Technology (IELT), Certificate

At Dunwoody College of Technology, the Electronics Technology certificate provides evening students with the entry-level skills and theoretical knowledge needed to design and troubleshoot circuits utilizing the latest semiconductor devices, biomedical devices, microprocessors, and microcontrollers. Graduates from this program are prepared to enter the industry as assemblers, troubleshooters, calibration technicians, and field service technicians.

The course of study includes: basic electricity and electronics; digital electronics; microprocessors; and microcontrollers.

Arts & Sciences curriculum supports the technical coursework by enhancing the students' communication, mathematics, and critical thinking skills.

Credits earned in the Electronics Technology certificate directly transfer into Dunwoody's Industrial Controls & Robotics (ICON) or Electronics Technology (IELT) associate's degree programs.
