Our verdict on IMathAS
IMathAS is an open-source, web-based mathematics assessment and course-management system for educators and institutions. It is designed for homework, tests, and course activities that need algorithmically generated questions and automatic grading of numerical or mathematical-expression answers. Its audience includes instructors and institutions seeking control over deployment, reusable math content, and learning-management-system connectivity rather than a general-purpose programming assessment platform.
The product’s strongest depth is in math assessment. Educators can build question libraries and reusable question sets, display math and graphs, provide calculator-style entry, and allow graph creation. Supported formats include multiple-choice, matching, matrix, interval, multipart, graphing, and file-upload questions. A course gradebook can combine online and offline grades, while discussion forums and course-content posting extend the system beyond individual assignments. This breadth makes IMathAS suitable for structured mathematics courses with varied assessment formats.
IMathAS is distributed under the GNU GPL and is available as free, open-source software. It can be installed on an institution’s own web server using PHP and MySQL, and it connects with learning-management systems through LTI 1.1 and LTI 1.3 as both a consumer and producer. That deployment model fits organizations that can manage their own web infrastructure and want an adaptable math-focused system. Institutions looking for hosted convenience, broad subject coverage, or programming autograding should consider a different category fit; those prioritizing self-hosted algorithmic math assessment, course tools, and LMS integration should shortlist IMathAS.
