Erasmus University Rotterdam OMPT Requirements: Variant & Minimum Score by Program

Erasmus University Rotterdam, and specifically the Erasmus School of Economics (ESE), is one of the most prominent adopters of OMPT-style math placement testing among Dutch universities. Because ESE runs several distinct bachelor's programs with different quantitative demands, the required test variant and minimum score are not identical across the school — a detail that trips up a lot of applicants who assume "one OMPT score fits all."

International Bachelor Economics and Business Economics (IBEB)

For IBEB, Erasmus School of Economics accepts either of two variants: OMPT-A with a minimum score of 70%, or OMPT-B with a minimum score of 60%. Only your first attempt is considered — ESE does not accept resit scores for this requirement, which makes a single, well-prepared attempt far more important than it would be at a university that allows retakes.

Erasmus's own published case study on its use of OMPT confirms that the Econometrics-track programs use the OMPT-B variant, reflecting the heavier quantitative demands of an econometrics curriculum compared to a general economics degree. A higher-level OMPT-D option is also referenced as suited to STEM-adjacent quantitative programs. Erasmus has not published an exact minimum score for these tracks in the sources we could verify — if you're applying to one of these programs, confirm the current minimum score directly on your program's official admission page before you finalize your preparation target.

Why the "no resit" rule for IBEB matters so much

Most students preparing for a math placement exam assume they'll get at least one more shot if the first attempt goes poorly. Erasmus's IBEB policy removes that safety net entirely for this particular exam. Practically, this means your preparation timeline should front-load a full diagnostic mock exam weeks in advance — not days — so you have real time to close gaps before the one attempt that counts.

How to prepare given these specifics

Because IBEB accepts either OMPT-A at 70% or OMPT-B at 60%, it's worth understanding which variant plays to your strengths before you commit your single attempt: OMPT-B generally reaches slightly further into quantitative material than OMPT-A, so a student who is comfortable with the full topic range but not perfectly polished may find the lower percentage threshold on OMPT-B more achievable than a higher threshold on OMPT-A.

Exam.ify's practice tests are organized by difficulty level so you can rehearse at the level closest to your target variant, with full timed mock exams and worked solutions for every question. As with any admission requirement, always confirm the current variant and minimum score directly on Erasmus University Rotterdam's official admission pages before your exam, since requirements can be updated between intakes.
