“When the IIE set out to find a proctoring solution, we had very specific requirements that, until now, no platform on the market could meet. We needed something robust enough to handle very large student numbers without compromising stability, and accessible enough to work for students even when power supply or internet connectivity was unreliable. We wanted class-leading proctoring technologies to safeguard the academic integrity of every assessment, and—above all—a partner who would let us shape their product’s development roadmap, not just sell us a static, off-the-shelf solution. We needed someone agile, willing to tailor their offering to our needs, and ready to integrate with the other technologies in our EdTech ecosystem to deliver a seamless assessment experience. It was a tall order, but we’ve found all of this and more in The Invigilator App.” – Dr Mario Landman, Head Educational Technology and Innovation, IIE Advtech

They’ve already taken parts of the world by storm, and with this new Global funding, the stage is set for a truly global takeover!” – Dr Hendrik Botha, Head of Institution, Boston City Campus
