Numerus Clausus and Selection for Competitive BSc Programs at TU Delft

Several of TU Delft’s most popular Bachelor’s programs operate under a numerus clausus (limited seats) system, making admission highly competitive for international applicants, including students from India. For the 2026-2027 cycle, programs like BSc Aerospace Engineering and BSc Computer Science and Engineering remain limited.

With applications for the September 2026 intake now closed (deadline was January 15, 2026), here's a guide to understanding the system, based on official TU Delft procedures, to help future applicants prepare.

What is Numerus Clausus?

Numerus Clausus (NC) caps the number of students admitted to high-demand BSc programs at Dutch universities, including TU Delft. Instead of automatic admission for qualified applicants, candidates undergo a competitive selection to fill fixed spots. This ensures the program can handle enrollment without compromising resources like labs and faculty. At TU Delft, it's applied to programs where application numbers far exceed capacity, especially in engineering fields.

For 2026:

• Aerospace Engineering is capped at 440 spots.
• Computer Science & Engineering has 590 spots total (345 for English-taught track; 245 for bilingual Dutch-English track)

Other TU Delft BSc programs with NC include Nanobiology and Clinical Technology, but Aerospace and CSE are among the most competitive for internationals.

The Selection Process: Step-by-Step

All steps for international applicants can be completed remotely, which is a plus for students from India or elsewhere. The process combines motivation checks, aptitude tests, and academic performance to rank candidates.

Aerospace Engineering:

1. Application (Closed for 2026): Register via Studielink by January 15 (23:59 CET), then finalize in Osiaan (TU Delft's portal) for international qualifications.
2. Matching Phase (January-February): Access the Digital Learning Environment for mandatory assignments, including a Math & Physics level test and self-reflection exercises. This assesses fit but doesn't count toward ranking.
3. Academic Aptitude Assessment (by early March): A personality test on study scenarios- no preparation is needed.
4. Selection Exam (March 11, 2026): A timed online proctored exam testing mathematics, physics, and introductory Aerospace topics. Study materials and syllabus are provided post-application.
5. Ranking (April 15, 2026): Based on aptitude assessment + exam scores, the ranking is done. The top 440 get offers; others may reapply next year.

Once you are ranked within the top 440, a seat is offered. You must confirm by July 1, 2026, for the same for timely visa processing (takes 4-6 weeks).

Computer Science and Engineering

1. Application (Closed for 2026): Studielink by January 15; choose the English track for internationals.
2. Matching Elements: Assesses motivation/ fit (no ranking impact).
3. Selection Tests: On Mathematics and Systematic Reasoning & Logical Thinking.
4. Ranking (April 15, 2026): Test scores determine lottery categories (e.g., top performers in Category 1). 590 spots filled via ranking + draw.

Tips for Success for Indian Students

• Prepare Early: Use TU Delft's syllabus for exams.
• Apply Strategically: Deadlines are strict; next cycle opens October 2026 for September 2027.
• Alternatives: Apply to non-NC programs (e.g., Mechanical Engineering), where admission is based only on requirements. The deadline is April 1.
