IcfesBot — ConsiliumBots' WhatsApp AI Guidance Chatbot Reaches 430,000+ Colombian Students; National RCT Finds No Enrollment Gain

ConsiliumBots, a US/Colombia-based education-technology nonprofit, built IcfesBot, an AI-powered WhatsApp chatbot that helps Colombian secondary-school graduates understand and act on their own ICFES ('Saber 11') exam results. Distributed in partnership with ICFES, Colombia's national testing agency, the chatbot answers questions about eligible degree programmes, admission requirements and financial-aid options, using generative AI (including OpenAI's GPT-4 via an API partnership) to interpret each student's specific score profile rather than sending generic information.
Since ConsiliumBots began operating in Colombia in 2018, the WhatsApp-based service has scaled to reach more than 430,000 students nationwide in 2023. The project was supported by a $200,000 grant from The Agency Fund and a $110,000 research contract with Harvard University in 2023, and ConsiliumBots has stated plans to extend similar chatbots to Chile and the Dominican Republic.
A national-scale randomised controlled trial by economists Eric Bettinger, Michael Kremer, Felipe Lizarazo, Christopher Neilson, Christian Posso and Juan Saavedra — 'Moving Attention but Not Enrollment: Nudging College Information Search at National Scale in Colombia,' prepared as a working paper for the Journal of Development Economics (2026) — found that the nudge-based chatbot intervention shifted students' information-seeking behaviour without producing a detectable increase in actual college enrollment. The finding is a useful caution for similar low-cost nudge chatbots: reach and engagement do not automatically translate into changed enrollment decisions.
