eX:plain is a Dutch certification body which started (by its predecessor) in 2002 using Questionmark. It certifies vocational training across security, finance and health. Candidates include people already in work and students looking to enter the relevant field. In both cases, the certifications give employers and customers confidence that successful candidates have the modern skills they need to do the job well.

Given its volume of assessments, eX:plain needs the efficiency of computer-based testing. eX:plain’s team needs an assessment platform that can store over 1,000 questions. Crucially, they need a partner that can cater for a range of question types and formats.


By working with Questionmark eX:plain has fully digitalized its testing process.

It can quickly deliver a diverse range of assessments using videos, graphics and animations as well as a variety of question types.

The process is quick and efficient. The Questionmark platform instantly marks papers and compiles results. The reporting tool makes it easy to analyze those results.

It is agile. Questionmark’s wide range of functionality helps eX:plain adjust quickly to new scenarios. The item bank function makes it easy to store questions and use them for future assessments.
