  • Quality universities are asking: “Are you an IB student?”

Where did IB originate?

A group of talented, forward-thinking teachers at the International School of Geneva, with assistance from several international schools, created the IB Diploma Program in 1968. What started as a single program for internationally mobile students preparing for university has today grown into four programs for students aged 3 to 19 with schools in 159 countries offering IB programs to almost two million students worldwide. Mercyhurst Prep is the region’s premier IB school.
