What Technology School Electronic Systems (TUES), associated with Technical University-Sofia does

TUES (Технологично училище „Електронни системи" към Технически университет – София / Technology School Electronic Systems at Technical University-Sofia) is a public specialized technology secondary school in Sofia, Bulgaria, institutionally integrated with the Technical University of Sofia. Founded in 1988 and operating across grades 8–12, it admits students through competitive entrance exams and produces roughly 60 graduates per cohort, with 2,846 graduates cumulatively over a 35-year history. The school offers four IT specializations — Software Development (Разработка на Софтуер), Communications and Computer Networks (Комуникационни и Компютърни Мрежи), Intelligent Systems (Интелигентни системи, focused on AI and machine learning), and Robotics (Роботика) — supplemented by a Cisco Academy, AI & Software Club, Embedded Club, the student-run Hack TUES hackathon, TUES Talks podcast, Inspiration Talks lecture series, and the TUES Summer Camp Career Track.

The school's core operating model is a tri-institutional school-university-business integration: 40% of its teaching staff are university professors from TU-Sofia, 20% are TUES alumni, and students complete mandatory two-week summer internships at leading Bulgarian IT firms, culminating in a professional diploma thesis on emerging technologies. TUES is physically located on the TU-Sofia campus, students gain access to university labs and clubs, and top graduates receive direct admission to TU-Sofia without entrance exams. The Association of TUES Graduates (AZTUES / АЗТУЕС), founded in 2014, formalizes the alumni ecosystem and underwrites events, mentorship, and teaching support. TUES is consistently ranked 2nd in Sofia by entrance-exam score and is regarded as Bulgaria's #1 technology high school.

Commercially, TUES has no revenue model in the conventional sense: it is state-funded through the Bulgarian Ministry of Education, charges no tuition, and is not an investable entity. Its only paid offering is an optional extracurricular outdoor school program (Green School in Semkovo at ~300 EUR per student, covering transport, meals, accommodation, and insurance). Distribution is by academic merit (entrance exams), and growth vectors are qualitative — curriculum expansion (AI/ML), internationalization via Erasmus+ and INVESTech, and ecosystem formalization through AZTUES — rather than quantitative scaling.
