The Precision Instruments Department focuses on professional training by following the "Measurement and Control Technology and Instruments", a characteristic program in higher education. Passing the Engineering Education Professional Certification in 2013, it adopted a credit system with flexible learning years for undergraduate education. Students who complete and meet the program requirements are awarded a Bachelor of Engineering degree. Outstanding graduates can directly pursue master and doctoral degrees. Since 2013, the "Cultivating Outstanding Talents" program has been implemented, assigning a mentor to each new undergraduate student.

Renowned professors, including academicians and Chang Jiang Scholars, teach undergraduate courses, and foreign professors from well-known universities are invited to teach short courses. Among the courses offered, there are 2 national-level excellent courses, 3 Beijing municipal excellent courses, and 9 Tsinghua University excellent courses. Three courses have become massive open online courses at Tsinghua University. In 2020, four courses—"Fundamentals of Testing and Measurement Technology", "Fundamentals of Optical Engineering", "Fundamentals of Control Engineering", and "Optoelectronic Instrument Design"—were recognized as the first batch of national first-class undergraduate courses. In recent years, faculty members have published over 30 undergraduate textbooks. The textbook series "Fundamentals of Control Engineering (3rd Edition)", "Fundamentals of Control Engineering (3rd Edition) Exercise Solutions", and "Fundamentals of Control Engineering Laboratory Guide" were selected into the second batch of the "12th Five-Year Plan" for national-level undergraduate planning textbooks by the Ministry of Education. In 2020, the department won the Tsinghua University Annual Teaching Excellence Award and the Young Teacher Teaching Excellence Award. In 2021, it won the Tsinghua University Teaching Achievement Award and the National Excellent Textbook Second Prize, and four courses were rated as Tsinghua University excellent courses. In 2022, we won first, second, and third prizes in the engineering group of the 10th Tsinghua University Young Teacher Teaching Competition. In 2023, one course was newly recognized as a Tsinghua University excellent course. In 2024, we won the first prize of the China Instrument and Control Society Higher Education Teaching Achievement Award, the Tsinghua University Annual Teaching Excellence Award, two Tsinghua University excellent courses (re-evaluation), and three first prizes in the engineering group of the 11th Tsinghua University Young Teacher Teaching Competition. The department provides opportunities for outstanding students to excel through programs like the "Top-notch Innovative Student Training Project" and various science and technology competitions.
