When a candidate appeals, the score is not the evidence. The record is.

Certification and professional exam delivery software with proctoring and audit trails

High-stakes certification lives or dies on defensibility: evidenced item quality, documented marker agreement, proportionate integrity measures, and a record of who decided what and when. NUADU runs the whole chain and keeps the file.

Item banking with classical item statistics per item.
Layered, configurable integrity: identity check, lockdown browser, AI proctoring detecting 10 violation types, live and post-review.
Proctoring reports usable as evidence in appeals proceedings.
Tamper-resistant digital certificates, independently verifiable by the receiving employer or institution.
Live support during the session — the highest-stakes hour is not one you spend alone.

NUADU is the platform on which exams are authored, delivered, marked and reported. It does not issue official national certificates and does not present any third-party exam brand as a NUADU product.

Questions we get asked

What does a defensible record contain?

The item and its quality statistics, the delivery conditions, every integrity flag and its review, the proposed score with its evidence, and the named approver with a timestamp.

Can proctoring evidence be used in an appeal?

Yes. Proctoring produces reviewable reports rather than automatic failures; nothing is auto-failed without human review.

Is the integrity level configurable per exam?

Yes — measures are layered and matched to the stakes of the exam, from identity check only to lockdown browser plus live proctoring.

How are certificates verified?

Certificates are tamper-resistant and independently verifiable by the receiving employer or institution, linked back to the underlying record.
