The iSchool Advising Team, along with other educational student services, encounter obstacles in delivering swift guidance due to outdated technologies and an ever-expanding student-to-adviser ratio. In response, we introduce ISAAC (Informatics Student Auto Advising Cyclopedia), an open-source information architecture that centralizes advising information. By incorporating advanced features like searchable indices and data analytics, ISAAC facilitates prompt assistance for basic student inquiries and enables advisers to prioritize complex student interactions. With its extensible nature, ISAAC revolutionizes advising with the potential to adapt to future student service requirements, guaranteeing enhanced efficiency and accessibility to advising information for everyone.
