Developed for the chemistry dept. at the University of Utah, this is a visually minimal, highly efficient SaaS solution for online exams in a controlled context., designed to scale to thousands of users. The system allows for the administration and proctoring of timed exams, either remotely or within a testing center. Features include multiple question types, retries for partial credit, full control over user access and course registration, and consolidated analysis of exam results. The software employs a novel concept called item response theory in addition to the usual analysis of exam data, enabling the system to quantify both the aptitude of the test taker and the quality and difficulty of the question itself, allowing for automated rating of questions in the question bank for difficulty-based selection and offering the instructor and other admins details on which concepts lack adequate understanding among students. The software is currently being used by thousands of students at three universities and a handful of high schools. Tech: LAMP stack with SlimPHP, Twitter Bootstrap, and jQuery.
