CNA

What CNA does

CNA Idiomas (legal entity: Editora CNA Cultural Norte Americano S/A) is a privately held Brazilian language and education company founded in 1973 and headquartered on Avenida Paulista in São Paulo. The company operates a franchise network of 700+ schools distributed across all regions of Brazil, offering in-person instruction in English and Spanish to age cohorts spanning children (3-10 years), pre-adolescents, teenagers, adults, and active seniors (50+ years). CNA is the only language school network in Brazil authorized to administer all major international proficiency certifications (Cambridge, IELTS, TOEFL, TOEIC, and SIELE), having reached Cambridge English Platinum status (one of only four institutions in Brazil to do so) and having issued 135,000+ certifications over the past decade.

The company's product portfolio extends beyond language into technology education: programming and robotics courses for ages 7 through adult (delivered through the Ctrl+Play sub-brand), an artificial intelligence course, and an Influencer/Creator Economy online course, with new product launches continuing through 2025-2026. Technology infrastructure centers on the CNAGO/CNA Net learning platform combining synchronous live video (Zoom-based Live Class) with asynchronous content and AI-powered personalization, secured via Auth0, OAuth2, and JWT with TLS/SSL encryption. Exclusive content partnerships include Disney for children's English materials (up to age 8) and Edelsa for advanced Spanish conversation content. The company has accumulated 30+ national and international awards including 10 Cannes Lions (for the Speaking Exchange program), 33 consecutive ABF franchise excellence seals, and ELTons finalist recognition.

CNA's revenue model combines franchise licensing, recurring course tuition (subscriptions), per-stage teaching materials sales through Shopping CNA, exam registration fees from international certifications, and corporate/institutional programs (CNA na Empresa for B2B and CNA na Escola for schools). Go-to-market is primarily franchise-driven with direct-to-consumer online enrollment, supplemented by paid search, social media, blog/content marketing, the free Conversation Club community, and free experimental classes as top-of-funnel acquisition. The company reports compliance with ISO 27001, SOC 2 Type 2 security practices, GDPR, and CCPA, and is privately controlled by its founding/management group with no disclosed institutional investors.
