It has a nice variety of reports, a fire register (for display on desktop computers or handheld devices, such as mobile phones), simple configuration, and a dedicated Web site for all documentation. It is available for download for experienced Linux users, and there is also a subscription service available for those who just want to use it without the hassle of daily administration.
Open School Admin (OSA) is a Web-based school administration system primarily focused on ease of use and access to school information. It has been in continuous use and development for the past 7 years. It manages all aspects of school administration: student enrollment, class scheduling, mark reporting, attendance, user accounts, and room booking. Through the use of various plugins, it also manages email announcements (including automated attendance notices), government reporting, dorm room management, Alumni relations, etc. It is a standalone application written using a Perl/MySQL back end. It requires a Web server (Apache/Lighttpd tested) and should run out of the box on any Unix system. While OSA itself is very mature, the installation and setup is still a young and evolving process.
