What ExTH does
ExTH (Exameninstelling Toezicht en Handhaving, legal entity Stichting eXplain) is a Dutch non-profit foundation headquartered in Amersfoort that operates as the designated examination institution for Dutch public safety enforcement officers (Buitengewoon Opsporingsambtenaren, BOAs) and HTV vocational students. Its core function is administering legally-required certification examinations that gate entry to and continuation in the BOA profession, including the Boa Basisbekwaamheid (BOA Basic Competence), the Permanent Education and Training (PHB) cycle of four exams over five years across four enforcement domains (Openbare Ruimte, Milieu, Onderwijs, Openbaar Vervoer), HTV MBO diploma examinations, and Alcoholwet supervisor certification. Certificates issued by ExTH are formally recognized by Justis (Ministry of Justice and Security) as prerequisites for obtaining and renewing the akte van opsporingsbevoegdheid (enforcement credential), making ExTH a quasi-regulatory body with effectively mandatory demand from the entire Dutch BOA workforce.
ExTH's product platform combines a Computer-Based Testing (CBT) theory exam system built on the Questionmark platform (with secure browser, randomized item banks, and immediate provisional results) and a practical examination system using purpose-built exam street environments (examenstraten) staffed with trained actors, structured digital rubrics with weighted scoring criteria, and bodycam evidence for appeals. A new Amersfoort examination center opened in June 2026, supplementing existing Amersfoort facilities and certified external practical exam locations, with Lamark third-party CBT locations used for additional theory exam capacity. The MijnExTH portal enables individual candidate self-registration and iDeal payment, while educational institutions (ROCs) and employers register candidates in groups via invoicing.
Revenue is generated on a pure per-exam transaction basis (pay-as-you-go, no subscription model), with annual tariff schedules published as PDFs. Auxiliary fee streams include duplicate certificate issuance (EUR 27.50), appeal/complaint processing (EUR 48.40), and cancellation/rescheduling fees. The organization serves three primary customer segments: active BOAs across municipal, police, and public transport employers (recurring PHB demand), HTV MBO students pursuing vocational diplomas (one-time diploma demand with a 5-year PHB exemption), and Alcoholwet-designated municipal supervisors. Go-to-market is sales-led but relies almost entirely on its own website (exth.nl), the MijnExTH portal, and direct email communication, with no evidence of paid advertising or social media marketing. ExTH is governed by six examination committees drawing representatives from Nationale Politie, Openbaar Ministerie, municipalities, and public transport operators, reinforcing sector legitimacy. The organization has 25 employees and no disclosed funding, ownership changes, or institutional investors, consistent with its independent foundation status.

ExTH competitors and assessment
Company assessmentOthers
- Questionmark: Provider of the CBT platform (ondemand.questionmark.eu) that ExTH uses to deliver secure theory exams. Questionmark is comparable as the technology supplier enabling ExTH's computer-based assessment infrastructure rather than a direct competitor.
Regional players
- NCOI: Large Dutch vocational and higher-education provider serving working professionals. NCOI is comparable as a Dutch institution preparing students in regulated professions, though it operates as a training provider rather than examination body.
- ANVS (Autoriteit Nucleaire Veiligheid en Stralingsbescherming): Dutch regulatory authority that administers specialized credentialing for radiation and nuclear safety professionals. ANVS is comparable to ExTH as a Dutch quasi-governmental body that delivers sector-specific professional examinations tied to statutory authority.
Broad incumbents
- DUO (Dienst Uitvoering Onderwijs): Dutch government agency administering education-related registrations, funding, and credentialing. DUO is a broader incumbent in the Dutch education administration space with overlapping roles in credential verification and exam registration infrastructure.
- Pearson VUE: World's largest computer-based testing network, operating secure exam centers globally. Pearson VUE is comparable to ExTH's combination of Questionmark CBT delivery and the Lamark/external-location network that extends reach beyond a single owned facility.
- SBB (Samenwerkingsorganisatie Beroepsonderwijs Bedrijfsleven): Dutch organization governing vocational education (MBO), recognized by the Ministry of Education. SBB is directly comparable as the body that accredits ExTH's HTV programs and oversees the qualification framework within which ExTH operates.
- ETS (Educational Testing Service): Non-profit educational measurement organization administering high-stakes standardized tests (TOEFL, GRE, Praxis). ETS mirrors ExTH's model of developing, validating, and delivering standardized assessments whose results carry significant real-world consequences for test-takers.
- Prometric: Global computer-based testing and assessment delivery provider. Prometric is comparable as the infrastructure layer ExTH relies on (CBT delivery, multi-location exam administration), though at vastly larger scale and across many verticals.
Direct peers
- Cito: Dutch educational testing and assessment organization that develops and administers standardized tests for the Dutch education system. Cito is the closest analog as a Netherlands-based examination body operating with quasi-regulatory authority over credentialing outcomes.
- Bureau Wbtv: Dutch regulator administering credentialing and examinations for private security organizations under the Wbtv framework. Bureau Wbtv is structurally analogous to ExTH as a designated examination/registration body for a regulated Dutch public-safety-adjacent profession.
