At ITRC, we have developed a new approach to our educational programs with the creation of hybrid virtual/hands-on irrigation courses.  We offer both 100% online and 50-50 hybrid courses that combine web-based teaching with short-duration, hands-on laboratories at Cal Poly, San Luis Obispo.Our online courses combine the resources of online training videos, tutorials, reading material, and interactive assignments.  This new setting allows participants to access the theoretical materials for each subject from home and at their convenience before participating in the on-site field workshops. We currently offer a variety of online and hybrid course series:
