About JDJ International Open Schools
JDJ International Open Schools (JDJ IOS) is an international educational ecosystem developed within the JDJ Bachalski framework, in collaboration with accredited curriculum providers and a growing network of educational partners worldwide.
JDJ IOS was established during the COVID-19 pandemic as a response to the accelerating global shift toward flexible, online, and internationally aligned education. It represents a new model of learning — designed specifically for the needs of 21st-century students.
The foundation behind JDJ IOS is JDJ Bachalski — an international education brand built over more than three decades.
Since 1990, JDJ Bachalski has supported more than 200,000 clients across Central and Eastern Europe through study-abroad programs and language education — both overseas and within Poland.
Until 2011, JDJ Bachalski operated approximately 30 offices and branches across Poland and selected international locations, including a network of language schools, establishing one of the region’s most recognized private education brands.
JDJ Bachalski is part of the Bachalski Business Group — a family-owned group with activities across multiple sectors, including education (JDJ), media (Gorzow24.pl), and healthcare (Medi-Raj). The group was founded by Dariusz Jacek Bachalski.
JDJ International Open Schools represents the next stage in this long-term development — transforming decades of experience in international education into a globally accessible, flexible model.
JDJ IOS is co-founded and led by Wojciech Bachalski, who is responsible for the development and international expansion of the project.
