What Vereniging van psychodiagnostisch werkenden does

VVP (Vereniging van psychodiagnostisch werkenden) is a Dutch professional membership association founded in 1970 that represents psychodiagnostic workers (pdw'ers) — practitioners who perform neuropsychological assessments, intelligence testing, symptom-validity testing, and developmental diagnostics across healthcare, youth care, education, and other sectors. The association's stated mission is to promote the quality of the profession and represent the interests of its members regardless of their work sector. Its service portfolio includes the annual VVP-congres, a recurring webinar program, accredited continuing-education courses (Nascholing), a Cognitief Trainer course co-developed with Fontys Hogeschool, a job board (Vacatures), news and columns (VVP-Nieuws), the Beroepscode VVP, and the Kwaliteitsregister Psychodiagnostisch Werkenden administered through Registerplein.

VVP does not operate a proprietary technology platform; its website (devvp.nl) runs on WordPress and membership registration is handled through the external Banster platform (ledenvvp.banster.nl). The core infrastructure is a content and events engine layered on top of a credentialing function delivered in partnership with Registerplein. The association is a federation partner of FBZ (Federatie van Beroepsverenigingen in de Zorg), which negotiates Dutch healthcare collective labor agreements (cao GGZ and others) on behalf of VVP members.

The business model rests on annual membership dues, congress and webinar ticket sales (members free or discounted; non-members €7.50-€120), and partnership-driven training revenue (e.g., Fontys Hogercognitief trainer, RINO Groep courses, Pearson/Hogrefe test webinars). Member benefits include accreditation points via Registerplein, quality-register certification, access to congresses and webinars, professional networking, and tax-deductible union contributions through FBZ. Geographic scope is single-country (Netherlands); the headquarter address is not publicly disclosed, though the annual congress is held at Cursus- en vergadercentrum Domstad in Utrecht.

Others

• RINO Groep: Dutch training provider for psychologists and psychotherapists whose continuing education courses VVP promotes (with a 10% member discount). Functions as a content/training supplier to VVP members, not a membership competitor.
• Registerplein: Dutch external platform that administers the Kwaliteitsregister Psychodiagnostisch Werkenden on VVP's behalf and accredits VVP's events. Functions as enabling infrastructure rather than a competitor, but is integral to VVP's value proposition.
• FBZ — Federatie van Beroepsverenigingen in de Zorg: Dutch federation of healthcare professional associations that VVP is a member of; FBZ negotiates collective labor agreements for ten cao's. Functionally an upstream federation partner — comparable as a Dutch association infrastructure layer serving similar professional bodies.
• European Federation of Psychologists Associations (EFPA): Umbrella federation of European national psychology associations. Functions as an enabling layer above VVP and similar national bodies; comparable as a professional-association infrastructure tier rather than a direct competitor.

Emerging players

• Nederlands Jeugd Instituut (NJi): Dutch knowledge institute focused on youth, with partial overlap with VVP members working in youth healthcare diagnostics (e.g., ADHDcentraal Jeugd posted vacancies on VVP). Indirect overlap through shared practitioner audience rather than direct competition.

Direct peers

• Nederlandse Beroepsvereniging voor Toegepaste Psychologie (NBTP): Dutch professional association for applied psychologists with overlapping membership base and congress programming that VVP actively promotes. Comparable membership-association business model, similar Dutch-only scope, and similar use of continuing education events as a core member benefit.
• Landelijke Vereniging van Vrijgevestigde Psychologen & Psychotherapeuten (LVVP): Dutch membership association for independent practitioners in psychology and psychotherapy. Comparable structure: membership fees, accreditation, continuing education, and advocacy for self-employed professionals in adjacent disciplines.
• Vereniging voor Gedragstherapie en Cognitieve Therapie (VGCT): Dutch professional association for behavioral and cognitive therapy practitioners. Similar membership-association model with congresses, accredited training, and quality registers for a psychotherapy-adjacent specialty.

Broad incumbents

• Nederlands Instituut van Psychologen (NIP): Largest professional association for psychologists in the Netherlands; overlapping mandate in psychodiagnostiek (runs its own Psychodiagnostiek congress and the AST-NIP standard that VVP members reference). VVP is more narrowly specialized, making NIP a broader umbrella incumbent rather than a head-to-head competitor.

Regional players

• British Psychological Society (BPS): UK chartered professional body for psychologists; comparable role as a national membership and standards-setting association. Not in VVP's geography but is a structurally similar organization serving an adjacent professional community.
