After more than 25 years since the first editions, and as an evolution of the CASA-VLBI Workshops, the JIVE VLBI School https://www.jive.eu/jvs2025 was held from September 15-19, 2025. The school brought together 197 registered participants from 52 different countries at ASTRON/JIVE, U. Pretoria, and virtually. Participants had the opportunity to gain hands-on experience analyzing real-time e-EVN data observed during the school.

The school adopted a novel hybrid multi-hub format. Local groups convened in different hubs, including JIVE (the main hub with 45 participants), Pretoria (8), and Budapest (5). Additionally, approximately 60 participants joined the sessions online. The JVS also included streamed tours of the Hartebeesthoek telescope and the EVN correlator room, as well as tours to the Dwingeloo and Westerbork telescopes. Structured tutorials allowed students, in small groups of five with dedicated tutors, to experience the entire VLBI data lifecycle, from observation to calibration and imaging. At the end of the school, each group presented their results and experiences.

We express our greatest thanks to all lecturers, tutors, local individuals, and everyone who contributed to the success of the school and the visits to the telescopes at ASTRON, JIVE, Pretoria, HartRAO, CAMRAS, and all those who participated!
