Question generation: Questions can be algorithmically generated, and numerical and mathematical expression answers can be computer graded.
Course tools: The system includes announcements, text items, attachments, discussion forums, and a gradebook.
Math display: It supports math and graph display, calculator-style math entry, and point-and-click graph creation.
Sharing: Questions can be shared between instructors and schools, and question sets can be exported and imported between systems.
Assessment types: Question types include multiple choice, matching, essay, matrix, interval, graphing, file upload, and multipart questions.
LMS integration: IMathAS supports LTI 1.1 as both a consumer and a producer.
Hosting: The software can be installed on a web server, and the maker says the most up-to-date code is available through GitHub.
License and cost: IMathAS is free, open-source software distributed under the GNU Public License.
Support: The maker states there is no official support; users can access support forums through MyOpenMath and email the maker with questions.
Training and documentation: The site provides training videos, use guides, question-writing guides, and detailed feature and question-language documentation.
Security: The documentation says sessions are cleared from the database after 24 hours if a user does not log out, and student answers are evaluated client-side rather than server-side.
Technical requirements: The documentation lists PHP and MySQL as requirements and says the system uses standard PHP and MySQL without special compilation options or external programs.
Intended users: The maker describes the system as designed specifically for mathematics assessment and says it was not intended to be multipurpose.
