Naklada Slap

What Naklada Slap does

Naklada Slap d.o.o. is a privately-held Croatian scientific and professional publisher founded in 1992 (with the operating brand claiming continuity since 1985), headquartered in Jastrebarsko with a business office in Zagreb. The company operates four product verticals: (1) scientific and professional books across psychology, medicine, veterinary, stomatology, methodology, history, and therapeutic children's literature; (2) psychodiagnostic instruments — both adaptations of international tests (WISC-IV-HR, WAIS-IV-HR, MMPI-2, PAI, NEO, 16PF, ADOS-2, RCFT, Bender-Gestalt II, etc.) and locally-developed tools; (3) three peer-reviewed journals (Klinička psihologija, Suvremena psihologija, Časopis za socijalne djelatnosti); and (4) professional education and certification workshops in psychology, speech therapy, and Montessori methods.

The company has built a digital testing ecosystem comprising four platforms: e-Test (web-based, supports supervised and video-supervised remote testing), ePONS (desktop scoring program on a credit-based model), e-POTJEH (electronic language-screening tool for children), and mTestiranje (LAN-based network testing for organizations). Distribution is multi-channel: a direct-to-consumer e-commerce storefront at nakladaslap.com, a partner-bookstore network across Croatia, Slovenia, Bosnia and Herzegovina, and Serbia, and direct B2B sales of instruments to credentialed professionals.

The business model combines one-time book sales, one-time licenses for psychodiagnostic instruments, recurring journal subscriptions, usage-based electronic-testing credits (1 credit = 1 paper-pencil application), and professional-services revenue from training workshops. Customer segments span clinical and counseling psychologists, university medical and psychology programs, healthcare providers, speech therapists, and parents seeking therapeutic children's literature. The company holds membership in the International Test Commission (ITC), European Test Publishers Group (ETPG), and Association of Test Publishers (ATP), and its editor-in-chief holds leadership positions in the Croatian Psychological Society and Croatian Psychological Chamber.
