Learning and Assessment Software for eLearning

 Anand Software and Training, an innovative eLearning provider, released “Learning and Assessment Software  (LAAS)”  to help provide eLearning tools to students, institutes, and organizations.  The software is a complete solution for offering content and assessment exams online, be it an academic institute or an organization. The software consists of four modules as mentioned below:

      1. Author module
      2. Content module
      3. Exam module
      4. Reporting




The author module offers authors a means to create users, groups, exams, and content. The author may import or create a list of candidates and assign the select candidates to one or more groups. The groups may in turn be assigned one or more content/exam modules created by the author. Granular control of candidates, content, and exams is provided in the software. As may be seen in the figure above, it consists of  Author options, Exam Options, Group Options, Candidate Options, Content Options, and Import/Export. In a typical flow chart, the admin creates authors, and then the author(s) creates content, exams, and add groups (or classes) to one or more exams.  For complete features available with the authoring software, please check out the Author Engine home page.

Content module delivers content in various forms, including plain text, rich text, pdf, and multimedia. The content may be organized hierarchically. It is also possible to embed youtube videos in the content, without the need for reproducing or reformating the youtube videos. Also, Microsoft Office documents may be delivered with the content engine. For more information, please visit the Content Engine home page.


The exam module is responsible for delivering assessment tests to the candidates as chosen by the author. Questions may consist of simple text/html, pdf, exhibit-based, or multimedia. Several exam configuration options such as disabling some navigation buttons (for example, you don’t want the candidate to go back or provide a review) are provided.  As may be seen in the picture above, several features such as text resizing, full-screen view, night view, bookmarking, etc provided. For more information on exam engine features, please visit the exam engine home page.

The reporting module analyzes and provides the results in the format that is configured by the author. The overall pass, category wise or sub-category-wise scores may be displayed. It is possible to provide conditional pass criteria such as declaring an overall pass only if a candidate passes certain categories or sub-categories. The statistics are available on the server-side for further processing and analysis.

Note that the software is specifically designed for delivering content and assessments to students, and not a school management software that is widely available elsewhere. Rich features are built into the software for content creation, assessment, and reporting.  Download a free trial version of the software from the product home page, Learning and Assessment Software.
