Which German universities currently use the dMAT score as an actual admission selection criterion?

As of the first India cycle, only two universities formally weigh the dMAT score in admissions decisions: RWTH Aachen University for its MSc Battery Science and Technology in Engineering program, and Georg-August University Gottingen for its MSc Data Science program.

The Two Universities That Count It

RWTH Aachen weighs dMAT at roughly 80% of the admission decision for MSc Battery Science and Technology in Engineering, with the remaining 20% from your Bachelor's CGPA. Georg-August University Gottingen uses it for its MSc Data Science program. Every other German university does not currently treat the dMAT score as a stated selection factor for admission, though the result still appears on your APS certificate, and this list may expand as more universities adopt the dMAT going forward.

An Important Note for Indian Applicants

Note: for Indian (non-EU/EWR) applicants specifically, RWTH Aachen requires the GRE in place of the dMAT for this program; the 80/20 dMAT weighting applies to EU/EWR applicants. Confirm which applies to you via the program's official admissions page before prioritising either test. If your target program is not one of these two, redirect the time you would spend chasing a dMAT score toward your SOP, LORs, or language scores instead.

My Advice

Check this list against your actual shortlist before deciding how much prep time your dMAT score deserves. If you are targeting RWTH Aachen's Battery Science track specifically, prioritise your Subject Module practice heavily; for everyone else, treat the score as a documentation requirement, not a competitive one.
